IPS in drive!<br />

The Annual Assembly held in Hanover,<br />

Germany was extremely successful.<br />

The IPS National Committee of<br />

Germany had arranged a splendid<br />

program for us and a pleasant meeting<br />

place at the Hotel Jägerhof just<br />

outside the city. So it was no wonder<br />

that about eighty IPS members decided<br />

to get together for three days – it was<br />

defi nitely worth coming! During the<br />

whole time I sensed a relaxed and open<br />

atmosphere although there were important<br />

elections to be held and many<br />

decisions to be taken.<br />

At the Annual Assembly, the new<br />

Wim Tonnis <strong>Peat</strong> Award had its fi rst<br />

prize winners and what kind of winners!<br />

Dr Hans Joosten and Mr Donal<br />

Clarke were duly awarded for their<br />

distinguished contribution to peat and<br />

peatland science and industry, especially<br />

in the promotion of Wise Use.<br />

They both have had a great impact in<br />

developing the concept of wise use of<br />

peat and <strong>peatlands</strong> in open interaction.<br />

Once again, congratulations to the<br />

winners! IPS received very many excellent<br />

nominations for the award and<br />

they will be valid for two more years.<br />

In addition to this, the IPS Secretariat<br />

welcomes all new proposals for the<br />

next Award which will be conferred at<br />

the Annual Assembly 2007.<br />

The IPS Executive Board has now<br />

three new members and I want to<br />

welcome Håkan Bjur of Råsjö Torv<br />

from Sweden, Valerijs Kozlovs of the<br />

Latvian <strong>Peat</strong> Producers Association<br />

and Jutta Zeitz of the Agricultural<br />

Faculty of Humboldt University Berlin<br />

Editorial<br />

4 PEATLANDS <strong>International</strong> 1/2006<br />

to the Board. Also I want to thank all<br />

other candidates who stepped forward<br />

and accepted the nominations by their<br />

member countries. This open election<br />

system, in which candidates are<br />

known well in advance of the election,<br />

evidently makes IPS more interesting<br />

and transparent.<br />

I would also like to welcome Gerald<br />

Schmilewski from Klasmann-Deilmann<br />

GmbH, Germany as the new chairman<br />

of Commission II on the Industrial<br />

Utilization of <strong>Peat</strong> and <strong>Peat</strong>lands, and<br />

Bruno Berken of the growing media<br />

association CAS from France as the<br />

new Coordinator of the Horticultural<br />

<strong>Peat</strong> Working Group. At the same time,<br />

I want to express my warmest thanks to<br />

the retired Executive Board members<br />

Gerfried Caspers, Bernt Hedlund and<br />

Matti Hilli as well as to Donal Clarke,<br />

former Chairman of Commission II,<br />

for their devoted work in IPS.<br />

The Annual Assembly accepted the<br />

proposal of the Executive Board that<br />

Sweden should host the IPS <strong>International</strong><br />

<strong>Peat</strong> Congress 2012. There was<br />

a fair and challenging competition<br />

between Estonia, Latvia and Sweden to<br />

host the event. All candidate countries<br />

and their proposals were evaluated very<br />

carefully. The IPS Congress, which is<br />

held every fourth year, is an excellent<br />

and advanced event for all peat and<br />

peatland experts. I hope that Ireland in<br />

Tullamore 2008 and Sweden in Stockholm<br />

2012 are even able to enlarge our<br />

main event, time after time.<br />

The Round Table Discussion of<br />

National Committees before the<br />

Jaakko Silpola<br />

Annual Assembly dealt with many<br />

issues among which the future of IPS<br />

was raised several times. We heard<br />

very good descriptions of why some<br />

countries have adopted new rules for<br />

National Committees in order to open,<br />

activate and enlarge the peat society<br />

within their countries.<br />

I strongly believe that each National<br />

Committee is able to signifi cantly<br />

increase its membership by attracting<br />

researchers, students, businessmen and<br />

consultants, company experts, teachers,<br />

journalists, artists and active citizens.<br />

Why should we gather new members?<br />

The answer is that open access is one<br />

of our key values and communication<br />

is another. An IPS National Committee<br />

is a perfect platform for all kinds<br />

of experts and stakeholders related to<br />

peat and <strong>peatlands</strong> who together can<br />

promote and advance the fruitful and<br />

wise use of peat and <strong>peatlands</strong> as well<br />

as the objectives of the IPS.<br />

The next Annual Assembly of<br />

National Representatives will be hosted<br />

by the Latvian National Committee<br />

on 24- 26 May 2007. The program<br />

will certainly be interesting, including<br />

a study tour and several unoffi cial and<br />

offi cial meetings. IPS will maintain its<br />

efforts to organize topical and wellprepared<br />

events in which it is easy for<br />

all people to participate. See you again!

From the President’s Desk<br />

Climate Change Working Group:<br />

The next big exercise for IPS<br />

More than one year ago, on 20 February<br />

2005, the IPS Executive Board held<br />

a sauna meeting aboard a ferry on the<br />

Baltic Sea. There was only one item on<br />

the agenda. What next after the Wise<br />

Use Guidebook, an exercise of several<br />

years between the <strong>International</strong> <strong>Peat</strong><br />

<strong>Society</strong> and the IMCG, the <strong>International</strong><br />

Mire Conservation Group. After<br />

the second round in the steam room, a<br />

topic emerged, not a new one but the<br />

highly important, debatable and timely<br />

current issue of <strong>Peat</strong>lands and Climate<br />

Change.<br />

The topic was then discussed thoroughly<br />

within the recently established<br />

Scientifi c Advisory Board (SAB) of<br />

IPS at its second meeting in Warsaw,<br />

Poland. Having accepted the topic<br />

unanimously, SAB was asked to draft<br />

terms of reference for an Expert<br />

Group to be invited to develop the<br />

idea and work out an action plan for<br />

dealing with the complex issue of<br />

<strong>Peat</strong>lands and Climate Change. Each<br />

of the eight IPS Commissions then<br />

nominated a representative for the<br />

Participants of the fi rst IPS <strong>Peat</strong>lands and Climate Change Working Group meeting on 1 February in Helsinki: Matti Saarnisto, Kari Minkkinen,<br />

Expert Group in order to incorporate<br />

expertise from different sub areas and<br />

viewpoints. On the fi rst day of February<br />

2006, 16 invited experts assembled<br />

in the House of Estates in a pretty<br />

cold Helsinki, where there was no sign<br />

of global warming.<br />

In my opening remarks, I called to<br />

mind that, in late November of the<br />

last year of the previous millennium,<br />

IPS and IMCG urged the contracting<br />

parties to the UNF Convention on<br />

Climate Change, better known as the<br />

Kyoto Protocol, to include the actions<br />

mentioned in a joint position paper<br />

of IPS/IMCG, the so called Freising<br />

Statement, in the Convention. As, since<br />

then, nothing of what the position paper<br />

emphasizes has changed, I take this<br />

6 PEATLANDS <strong>International</strong> 1/2006<br />

opportunity to repeat the statement<br />

here, from the present president’s desk.<br />

The CC-WG kick-off meeting in<br />

Helsinki was preceded by an “<strong>International</strong><br />

Seminar on Greenhouse impacts<br />

of the use of peat and <strong>peatlands</strong> in<br />

Finland” on 31 January, organized by<br />

the Finnish Forest Research Institute.<br />

In the seminar, ten highly professional<br />

papers were presented, describing<br />

results of a four-year project on<br />

greenhouse impacts of the Finnish<br />

<strong>peatlands</strong>. The seminar, chaired by Professor<br />

Jukka Laine, formed, together<br />

with the Freising Statement, an excellent<br />

basis for the discussions of the<br />

CC-WG meeting on the next day.<br />

Professor Laine, co-chaired by<br />

professor Matti Saarnisto, Secretary<br />

The Freising Statement<br />

The role of <strong>peatlands</strong> in man-induced climate change<br />

Position paper of IPS/IMCG addressed to the IPCC<br />

I. Introduction<br />

1. <strong>Peat</strong>lands contain about 35% of the global terrestrial surface carbon store;<br />

2. Development of pristine <strong>peatlands</strong> for agriculture and peat extraction stops<br />

carbon sequestration and leads to a decrease of the peat carbon pool on these<br />

sites; drainage of <strong>peatlands</strong> for forestry negatively affects peat carbon sequestration,<br />

but increased biomass may temporarily (1-2 centuries) compensate for sequestration<br />

losses; the rewetting of disturbed <strong>peatlands</strong> can contribute to carbon<br />

sequestration;<br />

3. Large scale fi res in <strong>peatlands</strong> cause substantial carbon release;<br />

4. The role of <strong>peatlands</strong> in the global carbon balance and climate change is presently<br />

not taken into account by the UN FCCC, Kyoto Protocol.<br />

II. Aims<br />

5. The UNF Convention on Climate Change should include actions designed to:<br />

• Promote the maintenance of existing carbon stores in <strong>peatlands</strong>;<br />

• Prevent the uncontrolled release of carbon from <strong>peatlands</strong>;<br />

• Maintain the carbon sequestering role of pristine <strong>peatlands</strong>;<br />

• Promote the restoration of disturbed <strong>peatlands</strong> for carbon sequestration;<br />

• Reduce, by wise use, the emissions of greenhouse gases from <strong>peatlands</strong> currently<br />

being used;<br />

• Promote further studies on carbon balance in <strong>peatlands</strong> and its role in global climate<br />

change.<br />

III. Action plan<br />

6. Create a data base on size and utilization of <strong>peatlands</strong> in order to obtain information<br />

about the carbon pool and its changes;<br />

7. Minimise the drainage of pristine <strong>peatlands</strong>;<br />

8. Reduce the emissions from existing agricultural, forestry, and peat extraction activities<br />

by wise use;<br />

9. Mitigate losses through restoration and other appropriate measures;<br />

10. Avoid the introduction of perverse incentives for climate protection matters,<br />

(such as peatland drainage for afforestation for the sole purpose of acquiring<br />

carbon credits).<br />

The contracting parties to the UNF Convention on Climate Change (Kyoto Protocol)<br />

are urged to include the above mentioned actions in the Convention.<br />

Freising, November 28, 1999<br />

Jens Dieter Becker-Platen Richard Lindsay<br />

General of the Finnish Academy of<br />

Sciences and Letters, conducted the<br />

CC-WG kick-off meeting through<br />

discussions on the purpose of the<br />

working group, on outcomes of the<br />

preceding seminar, other related research<br />

and working groups currently in<br />

operation in the fi eld of <strong>peatlands</strong> and<br />

climate change as well as the relation<br />

of the scientifi c activities and results to<br />

the IPCC and climate effect accounting<br />

methods in general. An important<br />

topic was the positioning of the IPS<br />

<strong>Peat</strong>lands and Climate Change Working<br />

Group towards other networks.<br />

In order to ensure the success of the<br />

two years work of CC-WG, a lot of<br />

emphasis was given at the Helsinki<br />

kick-off meeting to the objectives,<br />

methodology, timetable and the budget<br />

of the project.<br />

As a concluding outcome of the<br />

meeting, the working group decided<br />

that it would prepare an assessment<br />

report on “<strong>Peat</strong>lands and Climate<br />

Change”. Professor Jukka Laine will<br />

chair and coordinate the exercise.<br />

Invited CC-WG members will act as<br />

authors and contact points within their<br />

own fi elds of science. Funding of<br />

the CC-WG will be provided through<br />

the IPS budget, an issue which was<br />

handled at the IPS Convention in early<br />

May in Hanover, Germany. The CC-<br />

WG work was initiated without delay<br />

by asking authors to provide their topic<br />

proposals to Professor Laine, who will<br />

coordinate the content of the report.<br />

As an appetizer of the topics to<br />

be handled in the assessment report,<br />

this issue of <strong>Peat</strong>lands <strong>International</strong><br />

contains a short sample entitled “A lot<br />

of under 300-years-old peat layers in<br />

Finland“ by Dr. Markku Mäkilä of the<br />

Geological Survey of Finland. �<br />

A lot of under 300-year-old peat layers<br />

in Finland Text: Markku Mäkilä<br />

Markku Mäkilä from the<br />

Geological Survey of Finland<br />

analyzes the carbon storage<br />

abilities of Finnish mires<br />

according to their age, type<br />

and location.<br />

Geological peatland covers an area<br />

of 5.1 million ha in Finland, having<br />

a mean depth of 1.4 m. The Finnish<br />

national peat reserves total 69.3 billion<br />

m 3 in situ, while the carbon storage of<br />

Finnish mires is 3.2 billion t (627 t per<br />

hectare). The original peatland area<br />

covered ca. 10 million hectares.<br />

The long-term peat increment of<br />

Finnish mires has been calculated on<br />

the basis of 520 dated peat columns.<br />

The calibrated radiocarbon ages<br />

correspond to the present time, as<br />

50 years were added to them. The<br />

long-term peat increment in Finnish<br />

mires varies considerably, depending<br />

on many factors. For example, the rate<br />

of increment is higher in geologically<br />

young mires than in old ones (Fig. 1),<br />

higher in southern and western than<br />

in eastern and northern Finland, and<br />

higher in ombrotrophic bogs of southern<br />

Finland (Sphagnum area) than in<br />

minerotrophic mires (sedge area) of<br />

northern Finland (Fig. 1).<br />

The highest recorded rates are 2-3<br />

mm yr -1 in young coastal bogs and the<br />

lowest, under 0.1 mm yr -1 , in the uplands<br />

of northern and eastern Finland,<br />

where the bottom soil topography is<br />

sloping. The average peat increment<br />

rate is 0.32 mm yr -1 . The rate in areas<br />

of peat deeper than 2 metres is 0.4<br />

mm yr -1 , when northern aapa and palsa<br />

areas are excluded.<br />

The vertical peat increment rate<br />

was determined from 39 dated peat<br />

columns mainly representing the thickest<br />

peat layers of mires. Several datings<br />

were performed from separate levels<br />

in each column. The rate has varied<br />

greatly during the last 10 000 years<br />

(Fig. 2). Variations in peat increment<br />

rates can mainly be explained by the<br />

changes in vegetation composition and<br />

decomposition rates due to natural<br />

mire succession and variations in local<br />

conditions, especially moisture and<br />

nutrient conditions. However, the role<br />

of the climate cannot be ignored. Usually,<br />

about 5-20% of the plant biomass<br />

production is deposited as peat. Most<br />

of the biomass decays in the oxic peat<br />

layer at the surface and returns to the<br />

atmosphere as carbon dioxide (CO 2) .<br />

The proportion of the carbon<br />

store of mires contained in the surface<br />

peat layer (age 50-430 years, average<br />

250 years) was<br />

examined in 25<br />

peat columns of<br />

known age, dry<br />

bulk density and<br />

carbon content.<br />

This proportion<br />

was found to<br />

vary considerably<br />

(2-37%),<br />

approximately<br />

corresponding to<br />

the proportion of<br />

virgin peat but not<br />

the proportion of<br />

the energy content<br />

in the surface<br />

layer. However,<br />

due to the natural<br />

conditions, especially<br />

the moisture<br />

and nutrient<br />

conditions, areal<br />

differences were<br />

substantial and the<br />

proportion differed<br />

greatly even<br />

between adjacent<br />

mires. In addition<br />

to the age of the<br />

surface peat layer,<br />

the carbon store<br />

also depends on<br />

many other fac-<br />

tors such as the thickness of both the<br />

surface (0.1-1.0 m) and the total peat<br />

layer (0.5-7.8 m), and the age (710-10<br />

440 years) and carbon store of the<br />

total peat layer (180-2790 t ha -1 ).<br />

The highest proportions of carbon<br />

in the surface peat layer (>20%) were<br />

found in quite young mires under 1000<br />

years old in the coastal bogs of the<br />

highest uplift area. For example, in this<br />

type of bog the carbon content of surface<br />

peat layers aged 160 years was 114<br />

t ha -1 on average. The carbon accumulation<br />

(g m -2 yr -1 ) of this type of young<br />

bog can be compared to the annual<br />

carbon accumulation of young birch<br />

<strong>International</strong> Symposium on<br />

<strong>Peat</strong> in Horticulture - <strong>Peat</strong> in the<br />

Stranglehold of Interest Groups<br />

Amsterdam<br />

30 October 2006<br />

8 PEATLANDS <strong>International</strong> 1/2006<br />

The 5th <strong>International</strong> Symposium on “<strong>Peat</strong> in<br />

Horticulture” will be held in Amsterdam, the<br />

Netherlands on Monday, 30 October 2006.<br />

Traditionally, the Symposium will take place<br />

one day before the well-known <strong>International</strong><br />

Horti Fair, which is held on 31 October -<br />

3 November 2006.<br />

In 2003, the Symposium dealt with “Additives<br />

in Growing Media”. Discussed were additives<br />

like wetting agents, microbials, lime, growth<br />

regulators etc.<br />

This time, we will have lectures and discussions<br />

about PEAT. We will try to get answers<br />

on questions like:<br />

•<br />

•<br />

•<br />

•<br />

Is there an impact on our climate because<br />

of the use of peat?<br />

Can peatfi elds be transformed into nature?<br />

Are there rules and regulations concerning<br />

the extraction of peat?<br />

Is peat necessary in horticulture?<br />

The symposium is being coordinated by<br />

the Horticultural <strong>Peat</strong> Working Group of IPS<br />

(HOPE), Sympo <strong>Peat</strong> and the IPS Dutch<br />

National Committee.<br />

All details about the venue, the registration<br />

fees and speakers will be announced soon.<br />

sapling stands in cut-away peatland that<br />

is ash fertilized. The carbon content of<br />

surface peat layers aged 250 years in all<br />

25 dated columns was also 114 t ha -1<br />

on average. The lowest proportions<br />

were found in old mires with a thick<br />

peat layer (3-5%) and in old but quite<br />

thin mires with a low surface carbon<br />

content, especially in the northern aapa<br />

mire area (4-7%).<br />

Determining the average proportion<br />

of the total carbon store of mires<br />

contained in the surface peat layer is<br />

therefore diffi cult. However, recent<br />

accumulation rates of peat per unit<br />

time are generally higher than the apparent<br />

long-term carbon accumulation<br />

rates. This difference is mainly due<br />

to the longer period for decomposition<br />

as well as losses from mires due<br />

to fi res during the accumulation of<br />

the older peat. It is, however, possible<br />

that the carbon accumulation rate has<br />

increased due to the climate in recent<br />

years. Thus, the comparison is not so<br />

straightforward.<br />

The time scales relevant for the<br />

stabilisation of the CO 2 concentration<br />

in the atmosphere are, according to the<br />

IPCC Third Assessment report (IPCC<br />

2001), in the order of 100-300 years.<br />

About half of the emitted amount of<br />

CO 2 will be present in the atmosphere<br />

ered for the stabilisation of the atmospheric<br />

concentration, these biomass<br />

sources can be regarded as renewable<br />

for climate consideration.<br />

Generalizations based<br />

on our results must be<br />

treated with caution and<br />

it would be preferable to<br />

perform further tests and<br />

to examine thinner peat<br />

layers.<br />

More samples from<br />

different parts of Finland<br />

are needed to determine<br />

the exact amount and<br />

proportion of carbon<br />

found in under 300-year<br />

old peat layers. �<br />

2005), a very committed and active IPS<br />

member and former Chairman of the<br />

IPS Dutch National Committee who<br />

promoted and participated in many<br />

important peat projects.<br />

On 6 May 2006, before the Annual<br />

Assembly of National Representatives<br />

in Hanover, the Wim Tonnis<br />

<strong>Peat</strong> Award was conferred for the<br />

fi rst time. The IPS Secretariat had<br />

received seven nominations from<br />

IPS Secretary General Jaakko Silpola, Laureates Hans Joosten and Donal Clarke and IPS President<br />

Markku Mäkelä (left to right) in the garden of Hotel Jägerhof in Hanover-Langenhagen after the Wim<br />

the IPS Executive Board made<br />

a fi nal decision on who should<br />

receive the award. This year,<br />

the Board decided to confer<br />

two awards instead of one as<br />

Hans Joosten and Donal Clarke<br />

together were the driving force<br />

behind the most extensive<br />

exercise of IPS which involved<br />

compiling, editing and publishing<br />

the Wise Use Book as well<br />

as close cooperation between<br />

IMCG and IPS.<br />

In their acceptance speeches,<br />

the recipients emphasized<br />

particularly the need for further<br />

cooperation between the two<br />

organizations and their members.<br />

All nominations for the<br />

Award submitted in March/<br />

April 2006 will remain in force<br />

until 2008. Further nominations<br />

for 2007-2009 can be<br />

sent to the IPS Secretariat until<br />

31.12.2006. We warmly congratulate<br />

the laureates! �

25 Years Mire Conservation<br />

Programme in Germany’s Lower<br />

Saxony Text: Eckhard Schmatzler, Gerfried Caspers<br />

Translation: Susann Warnecke<br />

The Annual Assembly 2006<br />

of IPS was held in Hanover,<br />

the capital of Lower Saxony.<br />

Now it is time to talk about<br />

the efforts of all stakeholders<br />

in the Federal State who<br />

have been combining conservation<br />

and utilization of<br />

their <strong>peatlands</strong> in a truly<br />

wise manner.<br />

Historical development<br />

– Conflicts between<br />

agriculture, peat extraction<br />

and nature conservation<br />

In previous centuries, the development<br />

of the <strong>peatlands</strong> of Lower Saxony was<br />

characterised by different approaches,<br />

the aims of which were, respectively,<br />

their use as settlement areas and to<br />

produce food and fuel for the local<br />

population.<br />

In the 70s of the last century,<br />

however, the public more and more<br />

arrived at the view that the remaining<br />

Sphagnum as a renewable raw material: Sphagnum papillosum<br />

has established itself twelve months after its application in a<br />

large-scale fi eld trial. The mosses were spread and covered<br />

with straw in autumn 2004. Photo: Gerfried Caspers<br />

14 PEATLANDS <strong>International</strong> 1/2006<br />

raised bog areas of<br />

Lower Saxony should<br />

be preserved. At that<br />

time, about 60% of<br />

the raised bog area<br />

(155,000 ha) were<br />

in agricultural and<br />

forestry use, whereas<br />

bout 30,000 ha were<br />

used for peat extration.<br />

At that time,<br />

it was also planned<br />

to extract the peat<br />

from the last remaining<br />

raised bogs. In<br />

those years, it seemed<br />

to be impossible to<br />

overcome the different<br />

opinions of<br />

conservationists on<br />

the one side, and the peat industry on<br />

the other.<br />

On 1 April 1972, the Soil Extraction<br />

Act (Bodenabbaugesetz) came into<br />

force. The law determined how nature<br />

conservation bodies at rural district<br />

government level should<br />

deal with applications for<br />

peat extraction. The new<br />

application procedure and<br />

the documents required to<br />

obtain planning consent<br />

required, for the fi rst time,<br />

an overall plan for the<br />

use of the bogs according<br />

to the aims of nature<br />

conservation. Until 1972,<br />

agriculture had been the<br />

main after-use for <strong>peatlands</strong><br />

once peat harvesting<br />

had fi nished.<br />

By this means, the<br />

1970s brought about new<br />

Map of Lower Saxony. Source: Landesvermessung und<br />

Geobasisinformation Niedersachsen<br />

approaches on how to<br />

deal with Lower Saxony’s<br />

raised bogs, which became<br />

recognised as “wetlands<br />

of international importance” in the<br />

minds of the public, as designated by<br />

the Ramsar Convention in 1972. The<br />

aims for their maintenance were and<br />

are: the conservation of the near-natural<br />

<strong>peatlands</strong>, the preservation of the<br />

wet meadow areas and the rewetting of<br />

near-natural and partly extracted raised<br />

bogs.<br />

Working Group on <strong>Peat</strong>land<br />

Use – Land Management<br />

A Working Group, consisting of representatives<br />

of nature conservation<br />

and soil research bodies, was founded<br />

on 11 January 1977 following an order<br />

of the Ministry of Agriculture which<br />

was, at that time, responsible for nature<br />

conservation. Its purpose was to ease<br />

the continuously increasing confl ict between<br />

peat extraction and nature conservation<br />

by an intensive exchange of<br />

thoughts and experiences, among others,<br />

with the peat industry, agricultural<br />

stakeholders and the nature conservation<br />

authorities.

To achieve this, a state-wide survey<br />

and evaluation of the raised bog areas<br />

was initiated. Emphasis was laid, fi rstly,<br />

on giving advice and cooperation in<br />

carrying out the survey from a geological<br />

and nature conservation view.<br />

Survey and Evaluation of all<br />

Raised Bogs<br />

Within the framework of two research<br />

projects, all raised bogs of Lower Saxony<br />

were surveyed and evaluated. This<br />

inventory included mapping and evaluation<br />

of about 2,500 km 2 of raised<br />

bogs, as defi ned geologically.<br />

In 1980, an expert report dealing<br />

with more than 88 raised bog complexes<br />

used for industrial peat extraction<br />

was presented, entitled “Analysis<br />

of Lower Saxonian peat deposits to<br />

evaluate the resources worth extracting<br />

and their conservation value with<br />

regard to their optimal utilisation”<br />

(Untersuchungen an niedersächsischen<br />

Torfl agerstätten<br />

zur Beurteilung der abbauwürdigen<br />

Torfvorräte und der<br />

Schutzwürdigkeit im Hinblick<br />

auf deren optimale Nutzung).<br />

In 1983, all remaining 263<br />

raised bog complexes of the<br />

plains were surveyed and<br />

published in a report entitled<br />

“Analysis of Lower Saxonian<br />

raised bogs to evaluate their<br />

conservation value including<br />

a survey and evaluation<br />

of all remining near-natural<br />

raised bogs“ (Untersuchungen an<br />

niedersächsischen Hochmooren zur<br />

Beurteilung ihrer Schutzwürdigkeit für<br />

den Naturschutz einschließlich einer<br />

Bestandsaufnahme und Bewertung<br />

aller noch verbliebenen naturnahen<br />

Hochmoorfl ächen).<br />

Mire Conservation<br />

Programme Part I, Part II<br />

and Update<br />

The survey and evaluation reports<br />

presented led to the Lower Saxonian<br />

Mire Conservation Programme, which<br />

was adopted by the government of<br />

the Federal State on 1 December 1981.<br />

The Programme was published in two<br />

parts:<br />

• Part I (1981) for the raised bogs<br />

with importance for the peat<br />

industry and<br />

• Part II (1986) for the remaining<br />

raised bogs of the plains<br />

and Sphagnum cuspidatum have re-established in the area. Photo: Gerfried Caspers<br />

An update of the Programme was initiated<br />

by the Ministry of the Environment<br />

in 1994.<br />

Aims and Realisation of<br />

the Lower Saxonian Mire<br />

Conservation Programmes<br />

The Federal State of Lower Saxony<br />

accepted the Mire Conservation Programme<br />

and its commitment towards<br />

the country’s government to protect<br />

raised bogs. As the other Federal States<br />

of Germany do not, by far, have as<br />

many raised bogs as Lower Saxony,<br />

the conservation of these <strong>peatlands</strong> is<br />

especially important in this part of the<br />

country.<br />

The Mire Conservation Programme<br />

defi nes the following goals:<br />

•<br />

•<br />

•<br />

Conservation of the remaining<br />

natural and near-natural raised<br />

bogs<br />

Protection of small raised bogs<br />

Re-wetting of raised bogs after<br />

peat extraction and of disturbed,<br />

drained raised bogs with the aim<br />

of restoration as raised bogs<br />

To reach these goals it was decided to:<br />

•<br />

•<br />

•<br />

designate all current natural raised<br />

bogs and buffer zones, totalling<br />

540 km 2 , as nature protection<br />

areas and to maintain and improve<br />

them by support and development<br />

measures<br />

designate about 150 small raised<br />

bogs in a near-natural state as<br />

nature protection areas or natural<br />

monuments<br />

rewet peat production areas on<br />

raised bogs of about 300 km 2 , renaturate<br />

them and designate them<br />

as nature protecion areas.<br />

Conclusion<br />

On 1 December 2006, the Lower Saxonian<br />

Mire Conservation Programme<br />

will turn 25. On this occasion, it is time<br />

to take stock of its achievements, to<br />

present its success and to reward those<br />

involved in the project, but also to<br />

evaluate what is left to do.<br />

Today, all near-natural raised bog<br />

areas and small <strong>peatlands</strong>, altogether<br />

covering more than 50,000 ha, are<br />

15


protected and maintained as “Lower<br />

Saxonian landscape“.<br />

<strong>Peat</strong> production areas are required<br />

to be prepared for nature conservation.<br />

This means that, usually, they<br />

are rewetted and restored when peat<br />

extraction has fi nished. Today, about<br />

12,000 ha of former peat production<br />

sites are on their way to become mires<br />

and wetlands. The areas currently<br />

under production, amounting to about<br />

30,000 ha, will be prepared for a natural<br />

development afterwards.<br />

The valuable wet meadows threatened<br />

by intensive agricultural use shall<br />

be maintained, developed and integrated<br />

with the protection areas. Today,<br />

the large wet meadows are managed<br />

in a way so as not to disturb meadow<br />

birds. For instance, the populations<br />

of the curlew (Numenius arquata),<br />

the redshank (Tringa totanus) and the<br />

black-tailed godwit (Limosa limosa) were<br />

strengthened in recent years.<br />

One more example is the re-settlement<br />

of the crane, that has found its<br />

regular nesting areas in the <strong>peatlands</strong>.<br />

Water fowl, such as the teal (Anas crecca),<br />

is a regular guest in the re-wetted<br />

areas. Also butterfl ies and dragonfl ies,<br />

but also reptiles, can often be seen.<br />

The high importance of the raised<br />

bogs as habitats of very valuable bioeconosises<br />

(species thriving together)<br />

of typical peatland plants and animals<br />

has led to the designation of representative<br />

and important conservation<br />

areas in Germany and in Europe.<br />

Areas restored after peat-production<br />

also belong to this group.<br />

The raised bogs have been made<br />

accessible and thereby tangible and<br />

understandable for all people interested<br />

in them by creating bog walks,<br />

look-outs, information centres and<br />

peat trains. The conservation of the<br />

<strong>peatlands</strong> is widely accepted within the<br />

local population.<br />

Wise Use for 25 years<br />

In many regards, the mire conservation<br />

programme of Lower Saxony<br />

already carries the central ideas of the<br />

Wise Use of Mires and <strong>Peat</strong>lands, long<br />

before these were formulated by Hans<br />

Joosten and Donal Clarke in 2002.<br />

Not without reason, the initial meeting<br />

for the Wise Use concept among<br />

16 PEATLANDS <strong>International</strong> 1/2006<br />

Rewetted peat extraction area. Photo: Eckhard Schmatzler<br />

IMCG and IPS members was arranged<br />

in Lower Saxony’s Surwold in 1997.<br />

Especially, the guidance principles<br />

for Wise Use are inherent in the Mire<br />

Conservation Programme of Lower<br />

Saxony, for example:<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

the preparation and guidance work<br />

of the working group on mire<br />

utilization and land management,<br />

and the guidance by the German<br />

<strong>Peat</strong> <strong>Society</strong> (principle of public<br />

participation),<br />

the research projects surveying the<br />

raised bogs (principle of careful<br />

decision-making),<br />

the benefi ts for the society (principle<br />

of motivation),<br />

the publicly accessible basics<br />

(principle of public access to<br />

information),<br />

the protection of habitats (principle<br />

of species integrity) and<br />

the compensations<br />

(principle of<br />

compensation).<br />

Also in its dimension,<br />

the Lower<br />

Saxonian Mire<br />

Conservation<br />

Programme is<br />

one of the largest<br />

projects of its<br />

kind. Particularly,<br />

the areas of restored<br />

<strong>peatlands</strong><br />

are, with their<br />

12,000 ha, so far unique even on a<br />

worldwide scale.<br />

Future distribution of Mires<br />

in Lower Saxony<br />

It is estimated that, with the Mire Conservation<br />

Programme, about 112,000<br />

of the former 250,000 ha raised bog<br />

area of Lower Saxony can be restored<br />

to growing raised bogs. This area consists<br />

of:<br />

•<br />

•<br />

•<br />

•<br />

•<br />

current natural and near-natural<br />

raised bogs: 50,000 ha<br />

today’s restored areas: 12,000 ha<br />

industrially utilized areas, to be<br />

restored after peat extraction:<br />

30,000 ha<br />

future peat production areas, to be<br />

restored afterwards: 20,000 ha<br />

= total future raised bog area in<br />

Lower Saxony: 112,000 ha<br />

Restored and near-natural bogs in Lower Saxony.


Continuation of<br />

the Lower Saxonian<br />

Mire Conservation<br />

Programme<br />

The Mire Conservation Programme<br />

does not have any<br />

limited duration and its aims<br />

will also be valid in future.<br />

However, the agricultural use<br />

of the <strong>peatlands</strong> of Lower<br />

Saxony has already overstepped<br />

its peak. The areas are still used,<br />

but, because of microbiological<br />

decomposition, the fi elds are<br />

literally run down. In future,<br />

water-logged areas, bad drainage<br />

and other problems will<br />

make work for the farmers even<br />

more diffi cult and/or force them to<br />

abandon these fi elds.<br />

In Lower Saxony, the peat industry<br />

has at its deposal only the peat under<br />

the fi elds and meadows in agricultural<br />

use. Today, these <strong>peatlands</strong>, which have<br />

often been in agricultural use for more<br />

than 100 years, are, due to nutrient<br />

accumulation and soil modifi cation, no<br />

longer directly restorable into growing<br />

mires, even if they were rewetted<br />

properly.<br />

Most of the agriculturally-used<br />

former raised bogs have already transformed<br />

to marginal revenue sites, on<br />

which agriculture can not be carried<br />

out effi ciently anymore. Therefore,<br />

the industrial extraction of the peat<br />

from these wet meadows can produce<br />

restoration areas which, in the long<br />

term, can be transformed to new mire<br />

areas. The survey and documentation<br />

of these “returned areas”, guidance<br />

in their preparation and their fi nal<br />

inspection will be one of the most<br />

important tasks of mire conservation<br />

in the future.<br />

The regional development plan of<br />

Lower Saxony designates preferred areas<br />

for peat extraction. These resources<br />

will be suffi cient until the middle<br />

of the present century. Already today,<br />

extraction permissions until 2030 and<br />

further on have been issued.<br />

One special project is the research<br />

on how to cultivate Sphagnum mosses<br />

to be used as fresh biomass instead of<br />

white peat in horticultural substrates.<br />

First trials to initiate the growth of<br />

Sphagnum mosses on cut-over peat-<br />

Restored area after peat extraction at Gnarrenburger Moor. Photo: Gerfried Caspers<br />

lands have started and promise to be<br />

successful. The use of fresh Sphagnum<br />

mosses as an additive in horticultural<br />

substrates has shown encouraging<br />

results.<br />

Mire Conservation<br />

Programme also for Fens<br />

The Mire Conservation Programme of<br />

Lower Saxony originally covers only<br />

raised bogs. However, only if fens are<br />

also considered, will a complete mire<br />

conservation programm be achieved.<br />

Besides the raised bogs, fens are also<br />

typical of the landscape of Lower<br />

Saxony. Often both peatland types are<br />

connected and appear as a spatial unit.<br />

Compared with raised bogs, it has<br />

turned out<br />

that the<br />

protection<br />

and development<br />

of<br />

fens presents<br />

a more<br />

complex and<br />

sophisticated<br />

problem, not<br />

least because<br />

they are fully<br />

under agricultural<br />

use.<br />

While raised<br />

bogs, having<br />

their own<br />

water balance,<br />

can be seen<br />

seperately,<br />

as islands in<br />

the landscape, fens form an integrated<br />

part of the surrounding areas. Their<br />

effective conservation must therefore<br />

extend the area of the fen itself and<br />

also involve the surrounding landscape.<br />

The great success of the mire<br />

conservation in Lower Saxony shall encourage<br />

all stakeholders to move on in<br />

this direction and direct their attention<br />

also to the conservation of the fens in<br />

the Federal State. �<br />

Change (APN); the joint project of<br />

and CIFOR.<br />

The workshop noted that peat is<br />

one of the world’s most important<br />

carbon stores (storing about 30% of<br />

global soil carbon) and tropical<br />

<strong>peatlands</strong> are an extremely<br />

important component – storing<br />

30% of peatland carbon.<br />

The most extensive tropical<br />

<strong>peatlands</strong> are in SE Asia and<br />

cover about 30 million ha of<br />

which over 20 million ha are<br />

in Indonesia and 4 million ha<br />

in Riau province.<br />

Tropical <strong>peatlands</strong> play an<br />

extremely important global<br />

role for carbon storage and<br />

climate moderation as well as<br />

providing a range of other<br />

benefi ts such as biodiver-<br />

sity, water management, and<br />

livelihood support to local<br />

communities. The fundamental<br />

component of <strong>peatlands</strong><br />

is water. As water level decreases in<br />

<strong>peatlands</strong> so does capacity for sequestering<br />

and storing carbon.<br />

Current management practices<br />

in <strong>peatlands</strong> combined with climate<br />

change and variability are having a<br />

major negative impact on <strong>peatlands</strong>. In<br />

the past 10 years about 3 million ha of<br />

peatland in SE Asia have been burnt<br />

releasing 3-5 billion tonnes of carbon.<br />

In addition, the drainage of peat for<br />

oil palm and timber and pulpwood<br />

plantations as well as other agriculture<br />

and unsustainable logging is estimated<br />

to have affected more than 6 million<br />

ha and released an additional 2 billion<br />

tonnes of carbon over the same<br />

period. Thus the emission of carbon<br />

dioxide from <strong>peatlands</strong> in SE Asia<br />

represents one of the largest single<br />

sources of GHG emissions globally<br />

and is equivalent of 10% of the average<br />

global fossil fuel emission over the<br />

same period. This is accelerating global<br />

climate change.<br />

It is recognized that unsustainable<br />

management practices of <strong>peatlands</strong><br />

Pekanbaru, 26th January 2006<br />

are the main cause of peat fi res and<br />

associated transboundary smoke haze<br />

in SE Asia, which have massive health,<br />

social, economic and environmental<br />

impacts.<br />

Subsequent El Niño events will<br />

increase likelihood of drought and<br />

associated fi res which will have a<br />

major negative impact on <strong>peatlands</strong><br />

carbon stores and people in the SE<br />

Asia region. The next El Niño event is<br />

predicted within four years. The predicted<br />

changes to climate over the next<br />

50 years as a result of increasing GHG<br />

emissions, including hotter temperatures<br />

and changes in rainfall patterns<br />

combined with land use change and<br />

deforestation, will lead to increased<br />

degradation of <strong>peatlands</strong>, increased<br />

emissions of GHGs and further acceleration<br />

of climate change.<br />

The workshop proposed the<br />

following target: All stakeholders<br />

(including government, non-government,<br />

research, private sector and local<br />

communities) should urgently work in<br />

partnership to prevent peatland fi res<br />

and degradation. In addition, promote<br />

rehabilitation and sustainable use of<br />

<strong>peatlands</strong> in SE Asia to provide multiple<br />

benefi ts to the people in the region<br />

and safeguard the global environment.<br />

The workshop recommended<br />

relevant stakeholders to regionally and<br />

globally (targets particularly for Riau<br />

are available from the author):<br />

• Expedite the implementation of<br />

the ASEAN <strong>Peat</strong>land Management<br />

Strategy and associated National<br />

Action Plans. These should<br />

be complemented by plans at the<br />

provincial and local level in regions<br />

with extensive <strong>peatlands</strong>.<br />

• Strengthen policies and institutional<br />

arrangements for peatland<br />

management and strictly enforce<br />

policies and rules for the management<br />

and conservation of <strong>peatlands</strong>.<br />

• Stop the further conversion and/<br />

or drainage of deep peat and peat<br />

domes and maintain and restore<br />

the hydrology of peatland systems<br />

to prevent fi res, minimize GHG


•<br />

•<br />

emissions, and maintain ecological<br />

services.<br />

Improve current forestry, agriculture<br />

and plantation management<br />

practices to ensure that they<br />

contribute to the sustainability of<br />

<strong>peatlands</strong>.<br />

Promote international cooperative<br />

studies to assess the role of <strong>peatlands</strong><br />

in mitigating climate change<br />

and the potential future impacts<br />

•<br />

of climate change and land use on<br />

the peatland carbon pool.<br />

Undertake an assessment of the<br />

vulnerability of <strong>peatlands</strong> to climate<br />

change and extreme events.<br />

Effectively disseminate the knowledge<br />

generated by the scientifi c<br />

community for use by decision<br />

makers and to support the assessment<br />

processes and later develop<br />

adaptation strategies to guide<br />

Dutch Government Fights Fires in Kalimantan<br />

Almost annually, fires in<br />

Kalimantan destroy enormous<br />

areas for ever and<br />

cause shocking air pollution<br />

throughout the region. A<br />

network of NGO’s will start<br />

working to protect and restore<br />

these threatened areas.<br />

A major project aimed at the conservation<br />

and restoration of the peat<br />

swamps and their forest of Central<br />

Kalimantan has received the green<br />

light from the Netherlands’ Ministry<br />

of Foreign Affairs. The government of<br />

the Netherlands will be investing 5 million<br />

Euros in the coming two years on<br />

the basis of the “<strong>Peat</strong> Forest Amendment”<br />

which was passed in the Dutch<br />

parliament on November 14, 2004.<br />

The Central Kalimantan <strong>Peat</strong>lands<br />

Project (CKPP) will be implemented<br />

by four locally operating NGOs (Wetlands<br />

<strong>International</strong>, WWF, CARE and<br />

BOS), the provincial planning agency<br />

in Kalimantan (BAPPEDA) and<br />

the University of Palangkaraya. The<br />

project will be managed by Wetlands<br />

<strong>International</strong> head quarters based in<br />

Wageningen, the Netherlands.<br />

The network of environmental<br />

NGOs will focus on four key activities:<br />

1) fi re prevention, 2) restoration<br />

of the peatland hydrology (closing<br />

drainage channels to prevent drying of<br />

the peat soil), 3) reduction of poverty<br />

through small-scale developments and<br />

4) biodiversity conservation. Concrete<br />

examples of the project work are the<br />

closing of drainage canals to re-wet<br />

and re-green degraded fi re-prone areas.<br />

Large parts of Kalimantan consist<br />

of <strong>peatlands</strong>, originally mostly forest-<br />

ed. These tropical peat swamp forests<br />

are the living area for many threatened<br />

species. In this regard, the project will<br />

focus on the Sebangau National Park<br />

and the Mawas area which hold the<br />

largest remaining population of Orang<br />

Utan. In recent years, a large proportion<br />

of the peat swamp forests have<br />

been turned into wastelands as a result<br />

of deforestation, over-drainage and<br />

badly planned agricultural development.<br />

These developments made the<br />

area very vulnerable for fi res. Almost<br />

annually, huge fi res take place, destroying<br />

both internationally important<br />

nature areas and important agricultural<br />

and forestry assets. The fi res cause major<br />

air pollution problems in surrounding<br />

countries. In 1997 alone, peatland<br />

fi res in Indonesia contributed over 1<br />

giga ton of carbon dioxide, compara-<br />

The economic damage by smoke<br />

Knowledge Transfer Workshop for the<br />

Restoration of <strong>Peat</strong>lands, Québec<br />

On the sometimes cold and<br />

oftentimes windy days<br />

between 3 and 10 October<br />

last year, the <strong>Peat</strong>land<br />

Ecology Research Group of<br />

Université Laval in Quebec<br />

City played host to the<br />

latest Knowledge Transfer<br />

Workshop for the Restoration<br />

of <strong>Peat</strong>lands.<br />

Participants from many countries<br />

around the world were present, including<br />

Canada, the United States, Sweden,<br />

Finland, Estonia, France and Ireland.<br />

Included in these were representatives<br />

from universities right through<br />

to industry. Breaking from tradition,<br />

the working language for the workshop<br />

was English, in an effort better to aid<br />

the diffusion of ideas and information<br />

gathered as a result of the research carried<br />

out by the PERG.<br />

The main focus of the workshop<br />

was the Canadian approach to peatland<br />

restoration as described in <strong>Peat</strong>land<br />

Restoration Guide: Second Edition by<br />

20 PEATLANDS <strong>International</strong> 1/2006<br />

François Quinty and Line Rochefort<br />

(available to download from www.<br />

peatmoss.com/pm-restguide.php).<br />

However, many other interesting topics<br />

were discussed during other presentations<br />

given during the course of the<br />

workshop, such as those on cloudberry<br />

(Rubus chamaemorus) production<br />

(Guillaume Théroux-<br />

Rancourt and Mireille Bellemare),<br />

tree and berry bush<br />

plantations on residual peat<br />

substrates (Julie Bussières,<br />

Gabriel Caisse and Stéphanie<br />

Boudreau), the problem<br />

of invasive species (Claude<br />

Lavoie and Emmanuelle Fay),<br />

the restoration of fens (Martha<br />

Graf), peat policy and<br />

management in New Brunswick<br />

(Jacques Thibault),<br />

involvement of the peat industry<br />

The participants of the workshop learned from Francois Quinty (front) how the straw cover<br />

must be applied on the Sphagnum spreadings to guarantee the best growing conditions.<br />

While not in the conference halls,<br />

fi eld trips were made to <strong>peatlands</strong><br />

and to peat production facilities. At<br />

Premier Horticulture and Tourbières<br />

Berger, participants were given a tour<br />

of the factories and shown the methods<br />

used from harvest to packaging.<br />

Participants were also treated to an<br />

example of restoration procedures in<br />

practice following the Canadian approach<br />

on <strong>peatlands</strong> owned by Premier<br />

Horticulture at Verbois site. In addi-<br />

Line Rochefort, <strong>Peat</strong>land Chair of the Canadian <strong>Peat</strong>land<br />

Industry, was very happy to fi nd such large lumps of<br />

tion, <strong>peatlands</strong> that had already undergone<br />

these restoration practices were<br />

visited at Chemin du Lac, Bois des Bel<br />

and Sainte-Marguerite-Marie <strong>peatlands</strong>.<br />

Here, the successes attained using the<br />

Canadian approach were showcased<br />

and all seemed to agree that much<br />

progress has been made by the PERG.<br />

It was also aggreed that the Canadian<br />

approach could be used to create possible<br />

donor sites for future Sphagnum<br />

peatland restoration projects.<br />

The grandeur and resplendency of<br />

Quebec’s maple trees shone in myriad<br />

shades of gold and red intermingled<br />

with the deep greens of various coni-<br />

fers along the cliff<br />

tops and mountains<br />

that lined the road<br />

toward Lac St. Jean.<br />

The hills themselves<br />

seemed to mirror a<br />

carpet of Sphagnum<br />

and Polytrichum,<br />

albeit on a larger<br />

scale. The timing of<br />

the conference could<br />

not have been better,<br />

some were overheard<br />

saying!<br />

An appreciation<br />

of the merits of<br />

Many students of the <strong>Peat</strong>land Ecology Research Group of Université<br />

Laval (GRET) had joined the workshop.<br />

Jacques Gagnon explained how Sphagnum mosses and other mire<br />

vegetation is extracted at a donor site.<br />

the Canadian<br />

approach was instilled<br />

in all. Another<br />

aspect that<br />

was greatly appreciated<br />

by one<br />

and all present<br />

were the meals in<br />

restaurants and<br />

snacks in the fi eld<br />

provided by the<br />

Canadian Sphagnum<br />

<strong>Peat</strong> Moss<br />

Association,<br />

Fafard & Frères, Premier Horticulture,<br />

Les Tourbes Nirom and Tourbières<br />

Berger. These kept the spirits (and<br />

more importantly, the energy levels)<br />

topped up. The workshop was a great<br />

success and many ideas and opinions<br />

were given and shared as well as new<br />

contacts and links established. The<br />

next workshop is eagerly awaited. �<br />

More than 130 people from<br />

13 European countries met<br />

during workshops and field<br />

excursions in the Netherlands<br />

in October 2004 and in<br />

Latvia and Estonia in August<br />

2005 to exchange expertise<br />

on the restoration of raised<br />

bogs and coastal dunes.<br />

Both meetings were organized by the<br />

University of Nijmegen and by local<br />

organizers within the framework of<br />

the LIFE Nature Co-op project “Dissemination<br />

of ecological knowledge<br />

and practical experiences for sound<br />

planning and management of raised<br />

bogs and sea dunes”. The main aim of<br />

this project, funded by the European<br />

Commission, is a better international<br />

exchange of expertise to help optimise<br />

nature conservation and restoration<br />

measures.<br />

LIFE Co-op: Project for<br />

Restoration Management<br />

of Bogs and Dunes<br />

of ecosystem functioning as well as<br />

experience in carrying out restoration<br />

projects. There are, however, several<br />

problems and pitfalls in nature management<br />

that seriously hamper the<br />

process of increasing success.<br />

Apart from e.g. fi nancial, legal and<br />

spatial constraints, a considerable<br />

problem is the limited availability of<br />

international experience and up-to-date<br />

knowledge on ecosystem functioning<br />

to site managers who plan restoration<br />

measures. For instance, rewetting a<br />

peatland can result in further degradation<br />

of the area, if insuffi cient knowledge<br />

is available about local conditions<br />

or important biogeochemical processes<br />

affecting nutrient availability.<br />

Moreover, it is quite complicated<br />

to integrate all available information<br />

about the consequences of restoration<br />

measures for ecosystem functioning<br />

and for particular plant and animal species,<br />

let alone apply this information to<br />

a specifi c project area. Applying a similar<br />

restoration strategy in highly natural<br />

and heavily degraded sites will not<br />

always yield the optimal result and may<br />

have undesirable<br />

side-effects, e.g.<br />

on characteristic<br />

species that are<br />

still present.<br />

Integrated<br />

knowledge about<br />

the functioning<br />

of ecosystems<br />

and the demands<br />

plant and animal<br />

species pose to<br />

their habitat is<br />

required.<br />

Consequently,<br />

site managers<br />

may have<br />

diffi culty in<br />

determining the proper measures and<br />

the ‘fi ne-tuning’ necessary to bring<br />

about the desired habitat conservation<br />

or restoration in their project area. The<br />

results of a multi- and interdisciplinary<br />

approach (hydrology, biogeochemistry,<br />

vegetation and animal ecology) should<br />

be readily available for site managers to<br />

enable them to work with an optimal<br />

restoration strategy.<br />

Workshop and excursions<br />

People involved in nature management,<br />

policy making and scientifi c research in<br />

different disciplines participated in the<br />

workshops and fi eld excursions. The<br />

second workshop started on 22 August<br />

2005 in Jūrmala, Latvia, with welcome<br />

and opening addresses by Ivars Kabucis,<br />

chairman of the board of the<br />

Latvian Fund for Nature and Robert<br />

Schuddeboom, ambassador of the<br />

Netherlands in Latvia. Both stressed<br />

the importance of international cooperation.<br />

The second and third days were<br />

spent on fi eld excursions. The ‘dune<br />

people’ spent both days at sites along<br />

the Latvian west coast that are included<br />

in the LIFE-Nature project “Protection<br />

and management of coastal habitats<br />

in Latvia”, led by Brigita Laime,<br />

Vija Znotiņa and their colleagues from<br />

the University of Latvia. The ‘bog<br />

people’ visited Cena Mire and Ķemeri<br />

Mire on 23 August, led by Māra Pakalne,<br />

project leader of the LIFE-Nature<br />

project “Implementation of mire<br />

habitat management plan for Latvia”,<br />

and her colleagues of the Latvian Fund<br />

for Nature.<br />

The next day was dedicated to<br />

conservation and restoration of bog<br />

landscapes in the transboundary area<br />

of North-Livonia. Here, the Estonian


Ramsar sites at Nigula and Sookuninga<br />

Nature Reserves were visited, guided<br />

by Agu Leivits, Anneli Roosalu and<br />

their colleagues from Nigula Nature<br />

Reserve Administration.<br />

On 25 August, the bog and dune<br />

people re-united in Kabli, Estonia,<br />

for the plenary and parallel sessions<br />

in which site managers and scientists<br />

presented their practical experience<br />

and current ecological knowledge.<br />

These presentations are available at the<br />

project website. Various topics were<br />

discussed: threats leading to degradation<br />

of bog or dune habitats (e.g.<br />

increased atmospheric nitrogen deposition,<br />

drainage and fragmentation),<br />

practical use of scientifi c knowledge,<br />

setting proper objectives in restoration<br />

projects, planning and performance of<br />

conservation and restoration measures,<br />

and alternative strategies to restore<br />

habitats.<br />

The last joint part of the program<br />

was the Friday afternoon excursion<br />

to Luitemaa Nature Reserve, led by<br />

Marika and Mati Kose of the Estonian<br />

Ornithological <strong>Society</strong>. This area includes<br />

both coastal dunes and a raised<br />

bog. Here, restoration measures were<br />

undertaken within the framework of<br />

the LIFE-Nature project “Restoration<br />

and management of the Häädemeeste<br />

wetland complex”.<br />

Thirty-four people participated in<br />

the post-workshop-tour on the beautiful<br />

Estonian islands Saaremaa and<br />

Hiiumaa that was organized by Elve<br />

Lode, Urve Ratas and Kadri Vilumaa<br />

from the Institute of Ecology Tallinn.<br />

Discussing effects of drainage on hollow vegetation in Cena mire.<br />

Table 1. The PROMME-approach, a checklist containing six essential steps for nature<br />

restoration projects in order to avoid pitfalls.<br />

The workshops have also contributed<br />

to further cooperation and exchange<br />

of expertise in other projects.<br />

Last year, for example, people involved<br />

in the Polish LIFE-Nature project<br />

“Conservation of Baltic raised bogs<br />

in Pomerania” visited Latvian and Estonian<br />

bogs and Dutch experts joined<br />

their Lithuanian colleagues to discuss<br />

optimal restoration strategies for the<br />

degraded bog landscape in Zuvintas<br />

Nature Reserve. Danish, English and<br />

Dutch site managers and scientists did<br />

the same last March at the bog landscape<br />

of Lille Vildmose in Denmark.<br />

Decision support system<br />

In addition to both workshops and<br />

succeeding meetings, experience and<br />

ecological knowledge is disseminated<br />

by means of a digital decision support<br />

system, with practical guidelines for<br />

measures to help site managers and advisers<br />

take the proper steps in planning<br />

and restoration management. Without<br />

23


Participants of the workshop in Jurmala.<br />

ignoring the importance of socio-economic<br />

aspects, the system and guidelines<br />

focus on the ecological aspects of<br />

restoration management.<br />

Based on common sense and experience,<br />

the PROMME-approach (Table<br />

1) was adopted by the participants of<br />

both workshops as a useful framework<br />

for the setting-up of restoration<br />

projects. PROMME is meant to check<br />

for pitfalls in the restoration process<br />

and the decision support system gives<br />

access to information that shows how<br />

to avoid them.<br />

Although this system can not itself<br />

provide a complete design for each<br />

specifi c situation, it does provide the<br />

user with the ecological information<br />

necessary to design and carry out a<br />

restoration project on a specifi c site.<br />

First, the system encourages the user<br />

to make a profound analysis of the<br />

problem and its causes. If there is<br />

insuffi cient knowledge to defi ne the<br />

problem and the causal factors behind<br />

it properly, the system helps to identify<br />

knowledge gaps and suggests how to<br />

fi ll these gaps.<br />

Based on the problems and their<br />

causes, as well as the opportunities<br />

and limiting factors in and around the<br />

24 PEATLANDS <strong>International</strong> 1/2006<br />

project area, the user has to defi ne<br />

clear and realistic restoration objectives.<br />

Again, the support system helps<br />

to avoid pitfalls. Sometimes the measure<br />

itself (e.g. raising and stabilising the<br />

water table) is presented as an objective.<br />

In such projects there is a risk that<br />

restoration is declared successful when<br />

the measure is carried out in the right<br />

way (the water table is raised and more<br />

stable), irrespective of the effects on<br />

the functioning of the ecosystem and<br />

biodiversity.<br />

In the next step, potential restoration<br />

measures are presented, with<br />

information on positive and negative<br />

(side-) effects. Recommendations for<br />

monitoring programs are given and<br />

fi nally practical information necessary<br />

for the implementation of the measures<br />

is presented. This includes notes<br />

on the intensity and spatial scale of<br />

the measures adopted and feedback<br />

between monitoring results and the<br />

implementation of the measures introduced.<br />

An easy access to the essential<br />

literature or practical examples is provided<br />

at different steps in the decision<br />

support system.<br />

Sphagnum and more<br />

Restoration of degraded raised bogs<br />

generally focuses on retaining rain<br />

water to create suitable conditions for<br />

Sphagnum recovery. However, the success<br />

rate of rewetting methods (inundation<br />

or paludifi cation, rain water or<br />

groundwater) depends on the baseline<br />

conditions. The growth of Sphagnum<br />

depends not only on stable, high water<br />

tables, but also on nutrient poor water<br />

that contains enough carbon dioxide.<br />

Restoration measures will fail unless all<br />

essential conditions are met.<br />

Although a well developed Sphagnum<br />

vegetation is a prerequisite for a<br />

functioning raised bog, a bog system<br />

is more than wetness and Sphagnum.<br />

Research has shown that populations<br />

of rare and characteristic invertebrate<br />

species that have been able to persist<br />

in degraded bog remnants can respond<br />

negatively to rapid and large-scale<br />

rewetting. If such relic populations<br />

are still present in a project area, the<br />

restoration strategy should safeguard<br />

them, as they are the remaining sources<br />

for colonisation of rewetted sites.<br />

Furthermore, large-scale rewetting<br />

that is limited to retaining rain water<br />

generally results in similar changes on<br />

a large scale, leading to environmental<br />

homogeneity. Restoration of the<br />

regional hydrological system, including<br />

groundwater, may rehabilitate the<br />

heterogeneity in both ombrotrophic<br />

and more minerotrophic parts of<br />

bog landscapes. This heterogeneity is<br />

required to rehabilitate the plant and<br />

animal diversity of raised bogs. This<br />

kind of considerations is included in<br />

the decision support system. It is freely<br />

accessible at the project website.<br />

Do you have additional expertise,<br />

information, literature or practical<br />

examples that could help further to<br />

improve restoration projects? Please inform<br />

Wise Use and Restoration of<br />

<strong>Peat</strong>lands in Poland<br />

Invitation to a fi ve-day excursion in August 2006<br />

Following the 5th European<br />

Conference on Ecological<br />

Restoration, which will be<br />

held in Greifswald between<br />

22 and 25 August 2006,<br />

there will be a unique opportunity<br />

to travel across<br />

Poland focusing on peatland<br />

and mire landscapes.<br />

The organisers of the trip, “Wise Use<br />

and restoration of <strong>peatlands</strong> in Poland”,<br />

have included in the programme<br />

sites representative for almost all-possible<br />

stages of development, management,<br />

degradation and restoration of<br />

Central European <strong>peatlands</strong>.<br />

The trip has been organised by the<br />

Polish NGO “Save Wetlands”, with the<br />

patronage of <strong>International</strong> <strong>Peat</strong> <strong>Society</strong><br />

(IPS), <strong>International</strong> Mire Conservation<br />

Group (IMCG) and <strong>Society</strong> for<br />

Ecological Restoration <strong>International</strong>,<br />

Chapter Europe (SERI), all of whom<br />

have also been involved in the organi-<br />

sation of the conference sessions<br />

on peatland restoration.<br />

Programme in short<br />

The trip starts in the country<br />

of scattered bogs and<br />

fens in the hilly landscape of<br />

north-west Poland, where<br />

well-preserved mires neighbour<br />

degraded ones, and active<br />

restoration projects have<br />

been ongoing for a number<br />

of years. Then you will see<br />

the Noteć River Valley with its<br />

large areas of fens that have<br />

been reclaimed for more than<br />

200 years and, since then, managed<br />

by relatively intensive<br />

agriculture. What are the measures to<br />

minimise the environmental losses in<br />

such systems?<br />

The next points of the trip are the<br />

pearls of Polish mires: virgin fens<br />

of the Rospuda Valley and the best<br />

preserved seminatural fens of the Bie-<br />

Meadow with Polygonum bistorta at Calowanie Fen, habitat for one of the largest populations<br />

of the butterfl y Lycaena helle in Poland.<br />

The stork (Ciconia ciconia), here on a Calthion meadow<br />

near the village of Podbiel, is a rare species in Western<br />

Europe, but a common bird in Poland.<br />

brza Valley. Here, the organisers raise<br />

important conservation questions: why<br />

do some areas maintain high biodiversity<br />

without any human intereference,<br />

whereas others require high-cost<br />

vegetation management to prevent<br />

succession? How should this management<br />

be organised and implemented?<br />

What costs should the community pay<br />

to preserve such sites?<br />

We continue the excursion passing<br />

through the reclaimed Wizna fen<br />

– one of the largest land reclamation<br />

projects carried out in Poland during<br />

the communist time. What is the fate<br />

of such systems, designed for largescale<br />

collective farming, in the contemporary<br />

Poland? What are the effects<br />

of past drainage on biodiversity and<br />

agricultural use? What are the restoration<br />

prospects?<br />

The excursion concludes near<br />

Warsaw, where peatland biodiversity<br />

suffers not only from the past drainage<br />

and intensive use but also from the<br />

current pressure of the growing city.<br />

What should be the conservation and<br />

restoration strategies in such land-<br />

25


scapes? Are they different from those<br />

in remote areas? In Całowanie Fen, we<br />

will see the effects of pilot restoration<br />

projects and discuss their ecological<br />

and economical feasibility.<br />

Sightseeing included<br />

During the trip, the organisers also offer<br />

cultural and historical attractions.<br />

Visits in the Osowiec Fortress in the<br />

Biebrza Valley and sightseeing in Warsaw<br />

are some of them. For those keen<br />

on water adventures there is canoeing<br />

in the Rospuda river, whereas for mire<br />

walkers there are wet-foot hikes on the<br />

wild tracks in Biebrza Fens.<br />

Aim of the excursion<br />

The organisers hope to enhance onspot<br />

discussion on the limits of human<br />

interference in <strong>peatlands</strong> and on the<br />

prospects for their sustainable future,<br />

especially in the context of their multifunctional<br />

use and multiple needs of<br />

the society. The fi eld guidance will be<br />

offered by restoration practitioners and<br />

peatland scientists.<br />

26 PEATLANDS <strong>International</strong> 1/2006<br />

In memoriam<br />

Dr. Roy L. Ingram<br />

Roy Lee Ingram, Chapel Hill, North Carolina, USA, died October 3, 2005.<br />

Dr. Ingram was a long time member of the IPS and was well known in the<br />

United States for his research and publications dealing with North Carolina<br />

<strong>peatlands</strong>.<br />

He was born March 12, 1921 in Mamers, North Carolina. He attended<br />

the University of North Carolina at Chapel Hill from 1937-1941, graduating<br />

with a B.S. in Geology. He then went to the University of Oklahoma, earning<br />

a M.S. in Geology in 1942, before entering the U.S. Army Air Corps. After<br />

serving as a captain in the European Theater of Operations, he returned<br />

to the United States, attending the University of Wisconsin, attaining a Ph.D.<br />

in Geology in 1948.<br />

He began his career as a Professor of Geology at the University of North<br />

Carolina at Chapel Hill in 1947 where he remained until retiring in 1991.<br />

During that time he served two terms as chairman of the Department.<br />

From the mid-1970s through the mid-1980s, Dr. Ingram devoted much<br />

of his time to estimating and characterizing the peat resources of North<br />

Carolina. His background in sedimentology added much to the development<br />

of methods of investigating peat deposits. The culmination of his peat efforts<br />

appear in “<strong>Peat</strong> deposits of North Carolina,” published by the North<br />

Carolina Geological Survey.<br />

Dr. Roy Ingram will remain in our memory as an excellent colleague who<br />

contributed much to the understanding of the nature and properties of<br />

<strong>peatlands</strong> in the southeastern United States.<br />

Henry W. (Harry) Fraser<br />

Henry “Harry” Walker Fraser, 66, of Fort Gratiot, passed away at home,<br />

Tuesday, January 17, 2006, in the company of his family, after a lengthy battle<br />

with cancer. He was born in Southampton, England July 31, 1939. Harry<br />

spent his early years in Glasgow, Scotland. He married Elizabeth “Beth”<br />

McBain in 1963. Harry and Beth with their two daughters, Amanda and Gillian<br />

moved to Canada. They have lived in Fort Gratiot for the last twenty<br />

years. With his wit and “off-beat” sense of humor, Harry touched the lives<br />

of all who knew him. He was well loved and will be sadly missed. He is survived<br />

by his loving wife, Beth; and daughters, Amanda and Gillian, as well as<br />

extended family in Canada and Scotland.<br />

Harry Fraser was former Operations Manager of the Michigan <strong>Peat</strong> company<br />

and previous to that an operation Manager for the past Western <strong>Peat</strong> Moss<br />

Company in one of their operations located east of Winnipeg, Manitoba,<br />

Canada. He attended many IMPS functions starting with the 6th Congress in<br />

Duluth. On a post Congress trip to the Winnipeg area, we visited the operation<br />

that he managed. Some of the participants, might remember him. He<br />

attended the two Symposiums held in Duluth as well as those held in Athlone,<br />

Ireland and Sheffi eld, England and others. As Michigan <strong>Peat</strong> had one<br />

operation in Minnesota, Harry was a frequent visitor and also a member of<br />

the Minnesota <strong>Peat</strong> Association. As his obituary stated, he had a great sense<br />

of humor and his Scottish accent was great. He will be sadly missed.<br />

The nature guide to the<br />

Polish Biebrza Marshes<br />

The Biebrza Marshes, the best-preserved<br />

extensive peat bog area in<br />

Central Europe, is surely worth the attention<br />

of all lovers of unspoilt nature.<br />

Low moors, in the form of woodless<br />

mires as well as sedges and rushes,<br />

dominate the wetland valley of the<br />

Biebrza River (NE Poland). Raised and<br />

transitional moors as well as marshy<br />

forests and meadows can also be found<br />

there. Over 950 species of vascular<br />

plants testify to the richness of the<br />

fl ora, which includes 59 species under<br />

protection as well as 50 species entered<br />

in the “Polish Red Data Book of<br />

Plants”. Since 1993, this area has been<br />

protected as the Biebrza National Park<br />

– the largest National Park in Poland<br />

(59 223 ha), and in 1995 it was entered<br />

on the list of areas subject to protection<br />

under the Ramsar Convention.<br />

The Biebrza Marshes are already well<br />

known among professional ornithologists<br />

and amateur bird watchers. The<br />

book described here proves that this<br />

area also has many more natural attractions<br />

related to the non-regulated<br />

“wild” river and extensive <strong>peatlands</strong>.<br />

The nature guidebook under discussion<br />

is a joint publication of members<br />

of the Crossbill Guides Foundation<br />

from Nijmegen in the Netherlands<br />

(main author – Dirk Hilbers). The<br />

foundation began publishing guidebooks<br />

on the most interesting natural<br />

regions in Europe with this volume<br />

(2005). Aside from “Biebrza Marshes”,<br />

“The nature guide to the Bialowieza<br />

Primeval Forest (Poland)”, “The nature<br />

guide to the Coto Doñana and surrounding<br />

coastal lowlands (Spain)” and<br />

“The nature guide to the Extremadura<br />

(Spain)” were also published, and work<br />

is underway on subsequent volumes<br />

(Camargue, La Crau and Les Alpilles,<br />

France).<br />

The purpose of this new series of<br />

guidebooks is to provide reliable and<br />

Text: Andrzej Lachacz<br />

current information to various types of<br />

ambitious tourists and nature enthusiasts.<br />

However, the authors had more<br />

in mind than simply describing natural<br />

occurrences, as they also took on the<br />

challenge of clarifying the quintessence<br />

of ecosystem processes. They show<br />

the interrelations between abiotic and<br />

biotic environmental components by<br />

means of practical examples, as well<br />

as relations between certain species of<br />

plants and animals.<br />

The book has 107 pages, is light<br />

and can be easily taken along even on<br />

lengthy hikes. The book is divided into<br />

three sections: landscape, fl ora and<br />

fauna, followed by a practical section.<br />

The fi rst part (41 pages) provides basic<br />

information on the Biebrza Marshes<br />

and their surroundings (landscape,<br />

Biebrza river hydrology, various types<br />

of peat bogs, forests and other ecosystems,<br />

as well as history, historical<br />

buildings and monuments and nature<br />

protection). A detailed description is<br />

provided of peat bog ecosystems and<br />

their relation to hydrology as well as<br />

the characteristic diagonal (transversal)<br />

and longitudinal ecological zonality of<br />

the Biebrza River valley. This zonality,<br />

with water conditions unchanged by<br />

human activity, represents the uniqueness<br />

of the Biebrza Marshes.<br />

The next 17 pages describe fl ora<br />

and fauna. In addition to mammals and<br />

birds, for which this region is wellknown,<br />

amphibians, reptiles, insects<br />

and other invertebrates are also included.<br />

The third section of the book<br />

provides practical information on,<br />

among other things, accommodation<br />

and transport related to sites worth visiting<br />

as well as recommendations with<br />

respect to the behaviour of tourists in<br />

contact with nature. The book then<br />

describes 9 routes, including 5 tracks<br />

for walkers, 2 canoe routes, 1 to be<br />

covered by car and 1 possible to cover<br />

on foot, by bike or by car. All routes<br />

are described in a uniform manner and<br />

include a description of the course<br />

with the most important nature attractions<br />

indicated on schematic maps.<br />

The book includes a glossary<br />

clarifying diffi cult terms, as well as a<br />

list of animal and plant species names,<br />

which include their scientifi c names<br />

and equivalents in English, German<br />

and Dutch. The book includes many<br />

interesting colour photos presenting<br />

landscape as well as plants and animals.<br />

These pictures are an encouragement<br />

to visit the described locations. Due<br />

to the small format of the book, it is<br />

not a photo album, but the photos are<br />

a practical help in identifying areas of<br />

natural value.<br />

The guidebook will undoubtedly<br />

help increase interest in the Biebrza<br />

Marshes, which are permanently included<br />

on the map of Europe’s nature<br />

attractions. It also fulfi ls an educational<br />

role by familiarizing tourists with various<br />

aspects of the functioning of peat<br />

bog ecosystems. It is a good example<br />

of how much information can be gathered<br />

and presented in an attractive and<br />

concise form. �<br />

Symposium “Mountain and Upland<br />

<strong>Peat</strong>lands” in Poland<br />

A symposium on “Mountain<br />

and Upland <strong>Peat</strong>lands” was<br />

held in Kielce - Biale Lugi<br />

on 21 to 22 June 2004. The<br />

main objective of the event<br />

organized by the Institute<br />

of Geography and the Institute<br />

of Biology of the<br />

Swietokrzyski University in<br />

Kielce, was to introduce the<br />

results of studies conducted<br />

in the Biale Lugi <strong>Peat</strong> Reserve<br />

to a broad group of Polish<br />

peatland researchers, all<br />

members of the Polish National<br />

Committee of the IPS.<br />

During plenary and poster sessions,<br />

the participants had an opportunity to<br />

present the results of their studies in<br />

different regions: the Sudety Mountains,<br />

Roztocze, Lublin Upland, Volyn<br />

Upland, Przedborz Upland, Silesia<br />

Upland, Miechów Upland, Racibórz<br />

Basin, Tuchola Forests, Polanowska<br />

Plateau and Bialystok Plateau. A few<br />

studies of mires outside of Poland<br />

were presented either as a lecture - the<br />

Upper Harz region, or as published ab-<br />

30 PEATLANDS <strong>International</strong> 1/2006<br />

stracts - the Petersburg region (Kobak<br />

K., Krankina O.), the Gulf of Finland<br />

(Smagin V.A.), the Ukrainian Beskid<br />

Mountains (Kalinovych N.) and the<br />

carbonate bogs of Poland and Slovakia<br />

(Wolejko L.).<br />

Three presentations covered more<br />

general issues, such as the terminology<br />

used to defi ne wetlands (Bajkiewicz-<br />

Grabowska E.), high and transitional<br />

moors of southern Poland (Wozniak<br />

N.), and an assessment of the accumulation<br />

rate of Holocene biogenic<br />

deposits (Krupinski K.). On 21 June<br />

2004, four plenary and one poster sessions<br />

took place in the Senate Hall of<br />

the Swietokrzyski University, followed<br />

by an informal evening meeting around<br />

the dinner table.<br />

Field trip<br />

On 22 June, a trip to the Biale Lugi<br />

bog was organized. At the top of the<br />

dune, towering over a fl at-toppedmound<br />

of a raised bog dominated by<br />

phytocenoses of Ledo-Sphagnetum<br />

magellanici and Sphagnetum magel-<br />

Biale Lugi bog, a Sphagnetum magellanici association. In the central part, S. Zurek and P.<br />

Gwiazda are boring in the mire. On the right is Dr D. Urban.<br />

Text and photos: Slawomir Zurek<br />

lanici, the botanists and zoologists of<br />

the Swietokrzyski University reviewed<br />

the current state of the fl ora and fauna<br />

of the mire: vegetation (Przemyski A.,<br />

PhD), lichens (Prof. Cieslinski S.), fungi<br />

(Luszczynski J. PhD), bumble-bees<br />

(Bak J., PhD), amphibians and reptiles<br />

(Ichniowska-Korpula B., PhD) and<br />

mammals (Wypiórkiewicz J., PhD).<br />

The stratigraphy of the peatland<br />

was presented by Prof. S. Zurek<br />

followed by the presentation of P.<br />

Gwiazda, MSc, a member of the Student<br />

Geographers’ Scientifi c <strong>Society</strong><br />

of the Swietokrzyski University, who<br />

described the studies of two stratigraphic<br />

cross-sections, one from the<br />

central part of a raised bog, and the<br />

other from a region of fen with alder<br />

woods and riverside carrs. The latter<br />

cuts across the Czarna River, which<br />

overfl ows due to fl ooding caused by<br />

beaver. A 3.5 m deep bore, in the<br />

central part of the mire, disclosed the<br />

characteristic strata of the profi le:<br />

slightly decomposed raised bog peat<br />

(0.4 m), highly decomposed cottongrass<br />

peat (70-80% decomposition)<br />

with layers indicating fi res (0.7 m),<br />

medium decomposed transition bog<br />

peat (1.4 m) and slightly decomposed<br />

sedge-moss peat (0.8 m) deposited in<br />

the Younger Dryas (315-320 cm layers,<br />

dated 10880±250 BP acc. to radiocarbon<br />

dating) overlying a layer of loam<br />

and sand with gravel. After the presentation,<br />

the participants walked around<br />

the peatland and searched for familiar<br />

species of plants. The seminar ended<br />

in the afternoon and the participants<br />

were transported to Kielce.<br />

All printed materials, including the<br />

book “Biale Lugi <strong>Peat</strong> Reserve”, were<br />

handed out before the lectures.<br />

Presentations<br />

The presentations on 21 June took<br />

place during four plenary sessions, two<br />

in the morning and two in the afternoon,<br />

followed by a poster session.


During the fi rst session, E. Bajkiewicz-<br />

Grabowska lectured on terminology<br />

such as “swamp”, “marsh”, “wetland”<br />

and “peatland” from the point of<br />

view of a hydrologist. K. Szczepanek<br />

brought to attention issues related to<br />

the Biale Lugi peat bog, which need to<br />

be further investigated: interruptions in<br />

peat sedimentation, burning and plant<br />

succession. M. Nita and K. Wójcicki,<br />

from the Institute of Geography,<br />

Silesian University, presented a paleohydrological<br />

reconstruction of the<br />

Holocene in the Racibórz Basin based<br />

on pollen analysis and C-14 dating<br />

of old river-bed profi les of the Ruda,<br />

Klonica and Osloboga Valleys and distinguished<br />

the phases of ground water<br />

lowering during the Atlantic period<br />

and the rise in the Subboreal period.<br />

K. Tomaszewska dealt with the results<br />

of stratigraphic studies of Izera Valley<br />

mires, the subject of her post-doctoral<br />

(habilitation) dissertation. Most of the<br />

subfossil phytocenoses are identical<br />

with the current communities in this<br />

area. The initiation of swamping is an<br />

effect of invasion of swampy spruce<br />

associations.<br />

The second session was opened<br />

with a very interesting lecture by K.<br />

Tobolski on the Upper Harz mountain<br />

mires, based on the works of Jensen<br />

and Beug and on his own observations.<br />

The geological structure of <strong>peatlands</strong><br />

and pollen analyses were strongly emphasized.<br />

J. Klementowski described in<br />

detail the role of cryogenic processes<br />

in the morphogenesis of subalpine<br />

mires in the Karkonosze Mountains,<br />

and disputed their classifi cation as<br />

palsa mires by Czech researchers.<br />

During the fi rst afternoon session,<br />

A. Cedro presented the results of<br />

dendroclimatic studies of pine-wooded<br />

raised bog and pinewood morasses of<br />

Biale Lugi. The width curve of pinetree<br />

radial growth of the 1851 to 2001<br />

period showed that precipitation and<br />

temperature conditions during winter<br />

and at the beginning of spring shaped<br />

annual growth. L. Wolejko characterized<br />

carbonate habitats of northern<br />

Poland and Slovakia such as: carbonate<br />

mires, montane alkaline mire-springs<br />

and petrifi cating springs.<br />

N. Wozniak, a PhD student of the<br />

Silesian University, investigated 40<br />

profi les of raised<br />

bogs and 6 profi les<br />

of transitional<br />

bogs from uplands<br />

and mountains in<br />

Poland, using dates<br />

based on pollen<br />

analysis and C-14<br />

dating. He identifi<br />

ed 5 basic types<br />

of succession for<br />

raised bogs and 2<br />

types for transitional<br />

bogs. He<br />

described the process<br />

of initiation of<br />

raised and transitional<br />

deposits,<br />

which started in<br />

the Atlantic period.<br />

B. Lorens characterized peat-forming<br />

vegetation communities in the Roztocze<br />

National Park.<br />

During the fi nal afternoon session,<br />

M. Nita and M. Ludwikowska-Kedzia<br />

described the vegetation of the Mazovian<br />

interglacial at a depth of 12.8-9.4<br />

m in the outskirts of the Biale Lugi<br />

peat bog. This is the fi rst locality of<br />

this interglacial from the Sietokrzyski<br />

Mountains. T. Molenda introduced the<br />

participants to the interesting issue of<br />

the swamping of excavated holes and<br />

fi sh ponds in the Silesian Upland. The<br />

presentations of the authors who did<br />

not attend the seminar (N. Kalinovych,<br />

T. Jurkovskaja, Z. Osadowski, L.<br />

Kucharski) were replaced by K. Lipka’s<br />

lecture on the accumulation of peat<br />

and gyttja in the Niedzica River Valley<br />

in the Miechów Upland, and by K.<br />

Krupinski’s presentation on an assessment<br />

of the accumulation rate of<br />

Holocene biogenic deposits. Until now,<br />

the compaction processes and the water<br />

content of deposits have not been<br />

taken into consideration during such<br />

assessment. Therefore the calculated,<br />

mean rate of accumulation, based on<br />

deposit thickness and radiocarbon<br />

analysis, is burdened with error, which<br />

is signifi cant in some cases.<br />

Poster session<br />

During a one-hour poster session, the<br />

authors presented their results and<br />

materials. D. Drzymulska summarized<br />

Biale Lugi bog with Dr A. Lachacz, Dr J. Luszczynski and Dr M.<br />

Kloss (left to right).<br />

a paleobotanical study of the Bialystok<br />

Plateau, mainly mires of the Knyszynska<br />

Primeval Forest (Machnacz, Stare<br />

Biele) and Taboly, Kladkowe Bagno<br />

and Borki (studies included in her PhD<br />

dissertation). M. Kloss and S. Zurek<br />

recorded similarities and differences<br />

between fossil vegetation succession in<br />

extensive upland bogs, like Biale Lugi,<br />

and montane mire (Zieleniec in the<br />

Bystrzycki Mountains). M. Obremska<br />

and K. Tobolski showed new pollen diagrams<br />

of <strong>peatlands</strong> located in the Tuchola<br />

Forests, dominated by kettle-hole<br />

mires, and lakeside and riverside peat<br />

bogs. J. Pokorny and Z. Golab talked<br />

about the wetlands of Ziemia Klodzka.<br />

D. Urban, I. Milosz, R. Blaszczyk and<br />

M. Slawinski described the <strong>peatlands</strong><br />

of Pagóry Chelmskie in the Chodelka<br />

River Valley and in the Lublin Upland.<br />

Conclusion<br />

The seminar went very well under<br />

the supervision of the secretary Jerzy<br />

Wypiórkiewicz, PhD and Iwona Wolinska,<br />

MSc. The participants expressed<br />

the opinion that such regional meetings<br />

should be continued in the future. �<br />

<strong>International</strong> Meeting on Cloudberry<br />

Cultivation in Baie-Comeau, Québec<br />

On 13 September 2005,<br />

a meeting on cloudberry<br />

cultivation was held at Baie-<br />

Comeau, on the North Shore<br />

of the St-Lawrence River, in<br />

Quebec, Canada.<br />

Researchers from Canada and Norway<br />

were invited to share their knowledge<br />

on cloudberry cultivation. This included<br />

plantations on cut-over <strong>peatlands</strong> as<br />

well as the improvement of established<br />

populations in natural habitats.<br />

Cloudberry grows in boreal<br />

<strong>peatlands</strong>, and its berries have been<br />

harvested and transformed for a<br />

long time, especially in Scandinavian<br />

countries. However, so far, the species<br />

has not been cultivated on a large scale.<br />

In response to an increasing interest<br />

by local populations to cultivate this<br />

species and an increasing demand on<br />

the market, several research projects on<br />

cloudberry have recently been initiated<br />

in Canada, Finland and Norway. Since<br />

this species does not reveal its cultivation<br />

secrets easily to researchers, a<br />

Cloudberry fruit.<br />

32 PEATLANDS <strong>International</strong> 1/2006<br />

meeting on cloudberry cultivation was<br />

organised last fall to exchange information<br />

on the latest fi ndings.<br />

<strong>International</strong> audience<br />

Sixteen participants took part in the<br />

meeting comprising managers from<br />

two peat companies (Berger and<br />

Premier Horticulture, Canada), six<br />

researchers from Laval University<br />

(Canada), two specialists from provincial<br />

governments (New-Brunswick<br />

and Québec), three researchers<br />

from Les Buissons Research Centre<br />

(Canada), and fi nally three researchers<br />

from the Holt, Kvithamar and<br />

Apelsvoll (Norway) Research Centres.<br />

Research leaders in cloudberry cultivation<br />

of each country present were Dr.<br />

Line Lapointe from Laval University<br />

(Québec, Canada) and Dr. Inger Martinussen<br />

from Holt Research Centre<br />

(Tromsø, Norway); leader in peatland<br />

ecology and management Dr. Line<br />

Rochefort (Laval University, Canada),<br />

in Rubus breeding Dr. Kristine Naess<br />

(Les Buissons Research<br />

Centre), and<br />

in pollination Dr.<br />

Adam Brown.<br />

The meeting<br />

included site visits<br />

and oral presentations.<br />

After tasting<br />

some cloudberry<br />

chocolates made by<br />

a local producer of<br />

Baie-Comeau, we<br />

visited the on-going<br />

experiments sponsored<br />

(a Québec funding<br />

agency) and by Les<br />

Cloudberry establishment in<br />

cut-over <strong>peatlands</strong>: lessons<br />

learned<br />

A series of trials testing optimal water<br />

table depth, peat type, rhizome length,<br />

planting depth and time of plantation<br />

as well as the effects of wind breaks<br />

and Sphagnum mulching was established<br />

in spring 2004. In some of those<br />

trials, rhizomes of the two female cultivars<br />

developed in Norway were compared<br />

with two Canadian clones collected<br />

in <strong>peatlands</strong> in New Brunswick<br />

and in Québec. The best establishment<br />

was observed with the Norwegian cultivar,<br />

Fjorgull, but overall, survival of<br />

the transplanted rhizomes was low.<br />

The meeting was thus a good<br />

opportunity to set up a list of possible<br />

explanations as well as potential<br />

avenues of research for improvement.<br />

Among explanations, we can mention<br />

the possible compaction of the peat<br />

while preparing the site for plantation,<br />

which would reduce the oxygenation<br />

of the rhizomes. However, trials of the<br />

Norwegian cultivars in Norway also<br />

led to poor survival rates when planted<br />

as rhizomes although compaction did<br />

not seem to be an issue. The researchers<br />

are more and more convinced that<br />

15 cm of rhizomes at transplantation<br />

might be too short to support shoot<br />

growth. Adding to this, the rhizome<br />

segments of the Canadian clones were<br />

maybe too old to produce new shoots.<br />

Norwegian researchers also pointed<br />

out the possibility that the water table<br />

might have been too high at the plantation<br />

site in spring and fall, although<br />

it was quite low during summer time.<br />

Better water management should be<br />

pursued in the future. These experi-


All participants in the Cloudberry meeting are grouped around Guillaume Théroux-Rancourt for further explanations. After planting cloudberry<br />

rhizomes on a section of cut-over peatland, Sphagnum moss was spread over the plot and covered with straw to prevent dehydration of the<br />

moss. Although this technique has been successfully used to re-establish a Sphagnum carpet, it does not seem to be a promising method on<br />

which to establish cloudberry.<br />

ments are carried out by Guillaume<br />

Théroux-Rancourt and Mireille Bellemare,<br />

both M.Sc. students at Laval<br />

University.<br />

A new trial was set up during the<br />

summer 2005 to mimic the semi-forested<br />

pine bogs of Finland, where, naturally,<br />

cloudberry exhibits its highest<br />

productivity. Here, on a cut-over area<br />

replanted with larch saplings, rhizomes<br />

and plugs of cloudberry will be planted.<br />

The usefulness of<br />

planting well rooted<br />

plants as opposed to<br />

naked rhizomes will<br />

be estimated as well<br />

as the benefi ts of this<br />

semi-forested condition<br />

with respect to<br />

winter snow accumulation<br />

and protection<br />

against spring frosts.<br />

Improving<br />

yield. Boron applications slightly improved<br />

yield and will be tested again<br />

next year. Higher doses of phosphorus<br />

will also be tested next summer since<br />

the initial trials had no impact on either<br />

plant growth or yield.<br />

Leaving the cut-over sites, we drove<br />

around the peninsula to visit a natural<br />

peatland where sectioning of rhizomes<br />

combined with soil fertilisation had<br />

been tested to improve the density<br />

and therefore the yield of cloudberry.<br />

“Slight improvements are only starting<br />

to show up two years after the treatments<br />

were applied.” explained Mireille<br />

Bellemare in the fi eld.<br />

Field site visits were followed by a<br />

tour of Les Buissons Research Centre.<br />

The different steps leading to clonal selection<br />

presented were in vitro culture,<br />

propagation in growth chambers and<br />

fi eld trials. This visit was supplemented<br />

Improving rhizome density and fruit yield in natural<br />

populations of cloudberry is a slow process according to<br />

Mireille Bellemare, a M.Sc. student.<br />

later by Dr. Kristine Naess who<br />

explained the strategy used to identify<br />

clones with a good potential. Lunch at<br />

Les Buissons Research Centre was the<br />

time for informal discussions about<br />

specifi c problems encountered in the<br />

growth of cloudberry and potential<br />

solutions.<br />

Oral presentations<br />

Dr. Inger Martinussen from the Holt<br />

Research Institute (Norway) presented<br />

an overview of the recent research<br />

projects on cloudberry in Norway.<br />

There has been a long-term project<br />

on cloudberry cultivar selection<br />

in Norway, which led to the commercialisation<br />

of two male and two<br />

34 PEATLANDS <strong>International</strong> 1/2006<br />

female cultivars. However,<br />

research on fi eld cultivation<br />

is much more recent. While<br />

Norwegian researchers were<br />

running fi eld trials with the<br />

Norwegian cultivars, private<br />

producers also started to<br />

plant rhizomes and plugs to<br />

either increase density in natural<br />

populations or to start<br />

new plantations. While plugs<br />

exhibited interesting survival<br />

rates, rhizomes, as in Canada,<br />

had a high mortality rate.<br />

Following these somewhat<br />

deceiving results from both<br />

Laval University researchers<br />

and by Dr. Inger Martinussen,<br />

it was encouraging to<br />

hear that Gaetan Chiasson<br />

and its team from Agriculture,<br />

Fisheries and Aquaculture<br />

Ministry of New-<br />

Brunswick (Canada) obtained<br />

better survival rates in plantations<br />

on cut-over <strong>peatlands</strong>,<br />

using the same cultivars and<br />

clones as those tested in Baie-Comeau.<br />

At this point, it is not clear why they<br />

got better results except for the fact<br />

that the peatland used was less compacted.<br />

In conclusion<br />

In Canada as well as in Norway, research<br />

on cloudberry cultivation is still<br />

far from the optimum goal of largescale<br />

production. We need to substantially<br />

improve the survival rate of rhizomes<br />

in cut-over peatland plantations<br />

before looking at ways to improve<br />

plant growth and eventually fruit yield.<br />

But we now know that the cloudberry<br />

cultivar Fjordgull can be grown under<br />

a more continental climate such as in<br />

the Baie-Comeau area, which<br />

should considerably increase<br />

fruit yield compared to Canadian<br />

clones once we fi nd ways<br />

to improve its initial survival<br />

and growth rate.<br />

Meanwhile, we need to<br />

fi nd local producers willing to<br />

propagate this cultivar under<br />

greenhouse conditions so that<br />

material would be readily available<br />

once we overcome the<br />

main cultivation problems. In well-established<br />

cloudberry populations, there<br />

are also many more experimental trials<br />

to be run in order to improve density<br />

and yield. Since Eastern Canada and<br />

Norway/Finland present quite different<br />

climatic conditions, promising<br />

results from each side of the Atlantic<br />

will need to be validated in each other<br />

country.<br />

Being at the very beginning of<br />

cloudberry cultivation, however, we<br />

can just expect that progress will be<br />

substantial over the next few years and<br />

that international collaboration will<br />

accelerates this progress. �<br />

The Imnati Mire in the Kolkheti<br />

Lowland in Georgia Text and photos: Andreas Haberl,<br />

Marina Kahrmann, Matthias Krebs,<br />

Izolda Matchutadze and Hans Joosten<br />

Imnati, the largest mire in<br />

Georgia, is a worldwide<br />

unique percolation bog with<br />

a characteristic vegetation of<br />

Saw grass and peat mosses.<br />

In spite of its status as a<br />

National Park and Ramsar<br />

site, the mire is threatened<br />

by human activities.<br />

The Kolkheti (Colchis) area in Western<br />

Georgia (Caucasus) at the coast of the<br />

Black Sea is known for its extensive<br />

and special mires that - situated between<br />

citrus groves and tea plantations<br />

- form a structural and functional transition<br />

between the mires of the boreal<br />

and those of the tropical zones (Joosten<br />

et al. 2003). The special character of<br />

the area and its mires brought Botch &<br />

Masing (1983) and Succow & Joosten<br />

(2001) to the distinction of a specifi c<br />

Kolkheti mire region within Eurasia.<br />

The characteristic mire type of this<br />

region is the percolation bog (Joosten<br />

& Clarke 2002), a dome-shaped Sphagnum<br />

mire only fed by precipitation,<br />

that – in contrast to bogs in other parts<br />

of the world - has slightly humifi ed<br />

and highly permeable peat over its total<br />

depth. This allows water to percolate<br />

through the whole peat body (Lamme<br />

2006). The absence of substantial<br />

surface-water<br />

fl ow prevents the<br />

differentiation of<br />

hummocks and<br />

hollows (Couwenberg<br />

& Joosten<br />

2005) giving these<br />

mires their typical<br />

smooth surface.<br />

The existence<br />

of percolation<br />

bogs in the<br />

Kolkheti lowland<br />

was - on theoretical<br />

grounds - predicted<br />

on the basis<br />

of the prevailing extremely high and<br />

continuous precipitation (Couwenberg<br />

& Joosten 1999). The worldwide fi rst<br />

percolation bog that was discovered<br />

and intensively studied was the mire<br />

Ispani 2 near Kobuleti in the southern<br />

part of the Kolkheti lowland (Kaffke<br />

et al. 2000).<br />

In order to test and improve the<br />

concept of percolation bog, the<br />

Imnati mire, with similar morphological<br />

features, was<br />

focus of further<br />

research.<br />

Imnati is situated<br />

in the centre<br />

of the Kolkheti<br />

lowland 30 km<br />

north of Ispani 2<br />

close to the Black<br />

Sea (Fig.1). The<br />

climate is characterised<br />

by continuousprecipitation<br />

(1661 mm<br />

a -1 ) and a high<br />

humidity (80%),<br />

with a high mean<br />

annual temperature<br />

(14.1°C) and<br />

hardly any frost.<br />

Imnati constitutes,<br />

with 5000<br />

ha of non forested mire, 11% of the<br />

peatland area in Georgia. It is part of<br />

the “Wetlands of Central Kolkheti”<br />

Ramsar site designated in 1997 and is<br />

incorporated in the Kolkheti National<br />

Park which was established in 1999.<br />

Imnati consists of two separate bog<br />

cupolas. The western cupola (Fig.2)<br />

was studied in detail in 2004 and 2005<br />

by Greifswald University (Germany)<br />

in cooperation with the Integrated<br />

Coastal Zone Management (ICZM)<br />

Centre Tbilisi, the Kolkheti National<br />

Park, and the Georgian botanist Izolda<br />

Matchutadze (Kahrmann & Haberl<br />

2005).<br />

<strong>Peat</strong> formation<br />

<strong>Peat</strong> formation in Imnati began approx.<br />

6000 BP (Nejstadt et al. 1965).<br />

Before that, the area was a lagoon<br />

separated from the Black Sea by a spit<br />

build up of sediments from the Rioni<br />

River. Over the clay and silt sediments<br />

of the lagoon, a peat body of 3 to 12<br />

m depth accumulated (Fig.3). The peat<br />

Fig. 3: Stratigraphy of the western part of the Imnati mire (Kahrmann & Haberl 2005).<br />

stratigraphy reveals two main phases<br />

of mire development.<br />

A fen phase started with the terrestrialisation<br />

of the lagoon by stands<br />

of reed (Phragmites australis) growing<br />

under nutrient rich conditions. <strong>Peat</strong><br />

accumulation led to a decrease in<br />

nutrient availability and to a vegetation<br />

dominated by sedges (e.g. Carex<br />

lasiocarpa, C. rostrata) and Purple moor<br />

grass (Molinia litoralis). Also Saw grass<br />

(Cladium mariscus) was abundant in this<br />

period which led to the local formation<br />

of Cladium peat. The fen phase lasted<br />

for approx. 4000 years because of continuous<br />

tectonic sinking of the area.<br />

For a short time tectonic subsidence<br />

was even faster than peat accumulation<br />

leading to a renewed establishment of<br />

Phragmites.<br />

Fig. 4: The Imnati mire with the Minor Caucasus in the background.<br />

36 PEATLANDS <strong>International</strong> 1/2006<br />

Finally, at about 2000 BP, peat<br />

accumulation rates exceeded the rate<br />

of sea level rise, the infl uence of rain<br />

water increased, and the bog phase<br />

with dominance of peat mosses (e.g.<br />

Sphagnum imbricatum, S. papillosum) and<br />

Purple moor grass started. Molinia-<br />

Sphagnum peat of up to 6 m thick<br />

raised the surface of the bog to more<br />

than 5 m above the current Black Sea<br />

level.<br />

The warm/humid climatic conditions<br />

led to the accumulation of very<br />

loose and hardly humifi ed Sphagnum<br />

peats with a characteristic high proportion<br />

of rootlets and stem bases of Purple<br />

moor grass. These features explain<br />

the large active porosity and hydraulic<br />

conductivity of the peat.<br />

Vegetation<br />

The recent vegetation of Imnati is<br />

composed of a few vascular plants<br />

and peat moss species. The major area<br />

of the mire is covered by a peat moss<br />

carpet with Yellow Azalea (Rhododendron<br />

luteum) and Purple moor grass.<br />

Remarkable are the co-occurrence of<br />

high coverages of Purple moor grass<br />

and sedges (50%) where peat mosses<br />

still cover 90%. Despite its southern<br />

location and warm-temperate climate,<br />

boreal mire fl ora elements like Roundleaved<br />

sundew (Drosera rotundifolia), Bog<br />

bean (Menyanthes trifoliata), White Beaksedge<br />

(Rhynchospora alba), and Wool<br />

fruited sedge (Carex lasiocarpa) are<br />

abundant. Invasive vascular plant species<br />

e.g. Polygonum thunbergii, Blackberry<br />

(Rubus fruticosus), Burr marigold (Bidens<br />

tripartita), and Microstegium japonicum and<br />

a lower coverage of peat mosses indicate<br />

human impact close to the margin<br />

of the mire.<br />

Extraordinary is the frequent occurrence<br />

of Saw grass (Cladium mariscus)<br />

that is found in large and vital stands<br />

overlying peat bog deposits up to 5 m<br />

deep. Saw grass is known as a basi-<br />

and calciphilous species that grows<br />

in bogs only on shallow bog deposits<br />

where it is interpreted as a receding<br />

relict species of a former fen phase<br />

(Lutz 1938). Our measurements of<br />

electric conductivity and piezometric<br />

levels in the elevated parts of Imnati<br />

rule out that Saw grass refl ects upward<br />

seepage of calcareous groundwater:<br />

the sites are fully ombrotrophic.


Fig 5: High coverages of Purple Moorgras and sedges in a dense<br />

carpet of peat mosses.<br />

The warm-temperate climate of the<br />

Kolkheti lowland seems to enable the<br />

thermophilic species to cope with acid<br />

and nutrient poor conditions naturally.<br />

But also human impact like frequent<br />

burning may have enhanced Saw grass.<br />

Human impact is also refl ected in the<br />

peat stratigraphy in the uppermost 0.2<br />

- 0.5 m, in which remnants of Purple<br />

moor grass prevail. Also the absence<br />

of Sphagnum imbricatum, a fi re-sensitive<br />

species that was still abundant in the<br />

1930s (Dokturovski 1936), points in<br />

the same direction.<br />

Hydrology<br />

With respect to hydrological characteristics,<br />

Imnati shows an average phreatic<br />

water level of -8 cm below the mire<br />

surface and water table fl uctuations<br />

of less than 14 cm in average. The hydraulic<br />

conductivity of the peat (also at<br />

greater depths) has values 0.1 – 5 md -1<br />

higher than in other bogs worldwide.<br />

The hydraulic conductivity changes<br />

little over depth, with a decrease of<br />

generally only one order of magnitude<br />

from 0.4 – 3.9 m. This enables water<br />

to fl ow through the whole bog peat<br />

body (Lamme 2006). The high hy-<br />

draulic conductivity<br />

of the porous peat<br />

prevents surface run<br />

off in periods with<br />

high precipitation<br />

and leads to better<br />

nutrient availability<br />

through water fl ow<br />

(rheotrophy sensu<br />

Kulczyński 1949).<br />

On the other hand<br />

it would cause a<br />

running dry of the<br />

mire in dry periods<br />

that frequently occur<br />

in summer and<br />

may last for several<br />

weeks. Desiccation,<br />

however, does not<br />

happen because of<br />

the high elasticity of<br />

the peat that results<br />

from its high root<br />

content and the low<br />

humifi cation, which<br />

provide a good<br />

oscillation capacity<br />

of the mire surface. The mire surface<br />

sinks with the phreatic water level in<br />

dry periods and rises in periods of high<br />

rainfall (mire oscillation – “Mooratmung”).<br />

<strong>Peat</strong>, vegetation and water<br />

<strong>Peat</strong>, vegetation, and water<br />

are in a steady state in Imnati<br />

today. The abnormally<br />

high proportion of vascular<br />

plants for Sphagnum<br />

bogs induces higher evapotranspiration<br />

rates and<br />

a consequent larger water<br />

table drop down, resulting<br />

in higher rates of decomposition,<br />

which destroy the<br />

pore space and elasticity<br />

of the peat. This again<br />

would increase the water<br />

table fl uctuations. Extended<br />

periods of desiccation<br />

would hamper peat moss<br />

growth and would stimulate<br />

nutrient availability<br />

through decomposition,<br />

which would further boost<br />

the share of vascular<br />

plants (positive feedback<br />

loop). In Imnati, however, the vascular<br />

plants provide a “skeleton” for peat<br />

mosses whose extraordinary growth<br />

rates in this region (Krebs & Gaudig<br />

2005) prevent them from being outcompeted<br />

by vascular plants. As a<br />

result, highly porous and elastic peat<br />

accumulates, whose high storage and<br />

oscillation capacity stops the escalation<br />

of the positive feedback loop.<br />

Imnati is an impressive example that<br />

percolation bogs have resilience against<br />

irregular precipitation. The oscillation<br />

capacity is the decisive mechanism<br />

that helps this mire type to bridge dry<br />

periods “actively”. The high hydraulic<br />

conductivity of the peat avoids a<br />

drowning in wet periods “passively”.<br />

Utilisation of the peatland<br />

Mire utilisation only started 150 years<br />

ago with the cutting of marginal forests.<br />

In 1935, peat excavation started in<br />

the southern part of the mire, where<br />

it continued into the 1980s. The peat<br />

was mixed with phosphorus and other<br />

mineral fertilisers to be used for soil<br />

improvement in tea and citrus plantations<br />

(Tabadze 1963). Also the production<br />

of fuel pellets was tried out in<br />

1955/56. Their quality was, however,<br />

worse than from other <strong>peatlands</strong> in the<br />

Fig. 7: Human impact through subsistence economy - cattle grazing in the south of Imnati.<br />

former Soviet Union and the exploitation<br />

stopped.<br />

During Soviet times, hay for cattle<br />

was mechanically harvested in the<br />

southeastern part of the mire. After<br />

the collapse of the Soviet Union, the<br />

economic situation became worse.<br />

The forests at the mire margin were<br />

increasingly cut for fuel and private<br />

cattle more and more graze the Purple<br />

moor grass close to the settlements. To<br />

stimulate grass growth and to improve<br />

access for hunting (especially during<br />

the bird migration season!) the area is<br />

frequently burned.<br />

Nevertheless, the largely pristine<br />

Imnati mire is, because of its extent<br />

and its unique biodiversity values, one<br />

of the peatland treasures of Georgia.<br />

Its importance, ironically, increases<br />

by the current construction of an oil<br />

terminal and an associated railway in<br />

other parts of the Kolkheti Ramsar<br />

wetlands and National Park (Salathé<br />

2005). Despite its status as National<br />

Park and Ramsar site, from time to<br />

time ideas emerge to resume the utilization<br />

of the peatland.<br />

Pilot area for Sphagnum<br />

farming?<br />

Instead of concocting destruction<br />

of the world-wide unique Kolkheti<br />

mires for the production of horticultural<br />

substrates from peats, it is better<br />

to look for renewable alternatives.<br />

Because the climate guarantees yearround<br />

moss growth, peat mosses are<br />

38 PEATLANDS <strong>International</strong> 1/2006<br />

highly productive in the Kolkheti lowland,<br />

with Sphagnum papillosum reaching<br />

a production of over 10 tonnes<br />

dry weight per ha per year (Krebs &<br />

Gaudig 2005).<br />

The perennial rainfall and humidity<br />

cause the peat mosses to regenerate<br />

very well. This enables the production<br />

of Sphagnum biomass on formerly<br />

meliorated and excavated peatland<br />

and fallow mineral soil. Near Supsa,<br />

south of Imnati, a degraded peatland<br />

currently used as low-productive arable<br />

land, could be prepared as a pilot<br />

area for Sphagnum cultivation. These<br />

potentials will be assessed in further<br />

projects of the Institute of Landscape<br />

Ecology and Botany of Greifswald<br />

University. �<br />

Premier Tech Systems: Bringing<br />

Automation to the <strong>Peat</strong> Industry<br />

David Levesque gives an<br />

overview of the history of<br />

Premier Tech and what<br />

products and services it can<br />

today provide to the <strong>Peat</strong><br />

Industry.<br />

Looking back to 1989, the equipment<br />

adventure of Premier Tech Systems<br />

started when Bernard Bélanger, President<br />

& CEO of Premier Horticulture<br />

Ltd. (PHL), decided that the only way<br />

to lead the peat moss business would<br />

be to automate its operations as much<br />

as possible.<br />

At the time, market suppliers could<br />

not offer full automation and did not<br />

believe it could be done. That’s when<br />

Premier Tech Systems was born as the<br />

engineering entity of Premier Horticulture,<br />

with a small team of engineers<br />

determined to make it happen. Now,<br />

the team includes more than 450<br />

people, among them, some 35 who<br />

work full time for Research, Development<br />

and Innovation. The success of<br />

this company is based mainly on the<br />

importance of RD&I and its constant<br />

search for customer satisfaction.<br />

Equipment innovations for<br />

the peat industry<br />

To maintain its leading position in<br />

manufacturing processing and packaging<br />

equipment for the peat industry,<br />

Premier Tech Systems markets innovation<br />

products that will give its customers<br />

a competitive edge.<br />

First, there’s the 2-Head Vacuum<br />

Harvester, which is pulled by a tractor<br />

for optimum peat moss harvesting.<br />

With a tank capacity of 1,100 ft 3 (30.8<br />

m 3 ) and a working capacity of 7.5<br />

acres/hr. (3.03 ha/hr.), this harvester<br />

can be productive in a very short time.<br />

Besides being an effective harvester,<br />

even under unstable weather conditions,<br />

this unit’s aluminium construction<br />

means minimal pressure is exerted<br />

on the ground. Because of its light<br />

weight, it requires less pulling power,<br />

Premier Tech Headquarter in Riviere-du-Loup, Quebec.<br />

which ultimately results in better fuel<br />

consumption.<br />

Another innovation from Premier<br />

Tech Systems is the new EA-450<br />

Vertical Form, Fill and Seal Baler that<br />

makes its own bags from a roll of fl at<br />

polyethylene fi lm, resulting in reductions<br />

in packaging material and direct<br />

labour costs. This fully automated system<br />

packages compressible products,<br />

such as peat moss, at a density ratio of<br />

up to 2.5:1 and produces watertight,<br />

square-cornered bales<br />

of 25 to 300 litres. It is safe<br />

and designed to operate cleanly,<br />

smoothly and with minimum<br />

noise. It uses a proven electronic-impulse<br />

sealing technology<br />

and is equipped with a<br />

volumetric belt feeder that has<br />

a levelling device for accurate<br />

dosing.<br />

Lastly, there is the new and<br />

innovative EM-2000 Semi-Bulk<br />

Baler, a semi-automatic system<br />

specially designed to produce<br />

very large sized peat moss bales<br />

(up to 300 ft3 /8.5 m3 ). Rather<br />

than stretch wrapping the<br />

product, this new machine uses<br />

pre-made plastic bags, which<br />

produce a better looking bale.<br />

The bales produced also provide<br />

more protection for the<br />

bagged material during transport and<br />

storage, and the print on the bags is a<br />

good marketing tool.<br />

Customer satisfaction<br />

The customers of Premier Tech Systems<br />

can count on 22 fi eld service<br />

representatives in North America and<br />

Europe, 6 modem/remote service<br />

technicians, and 8 spare parts special-<br />

ists. The company is also considering<br />

starting a small service unit to ensure<br />

better proximity and technical support<br />

in the Baltic States and Scandinavian<br />

countries.<br />

Web portal for their customers.<br />

PM-5.COM was created in an effort to<br />

reach the next level in customer care<br />

and achieve an<br />

BOGLAND - A Protocol for Wise<br />

Use and Sustainable Management of<br />

<strong>Peat</strong>lands in Ireland<br />

In 2005, a three-year project<br />

named “BOGLAND” was<br />

initiated by the Irish<br />

Environmental Protection<br />

Agency and is being led by<br />

University College Dublin.<br />

The overall objectives of the BOG-<br />

LAND project are:<br />

• To quantify the main features of<br />

the peatland resource, notably<br />

extent and volume, biodiversity,<br />

hydrology, carbon balance and<br />

contribution to greenhouse gas<br />

fl uxes;<br />

• To assess vulnerability to environmental<br />

pressures and threats<br />

arising out of various kinds of<br />

exploitation (drainage, mining,<br />

forestry, energy, agriculture etc.);<br />

• To assess socio-cultural, economic,<br />

institutional and policy issues;<br />

• To integrate and synthesise the results<br />

of literature-based and fi eld<br />

studies and;<br />

Wise use of Irish <strong>peatlands</strong><br />

ment of the peatland resource in While the area of Ireland covered by<br />

Ireland.<br />

peat is considerable (over 16%), much<br />

of this has been extensively modifi<br />

ed by man. <strong>Peat</strong><br />

has been used in<br />

Ireland since prehistoric<br />

times but<br />

since the advent<br />

of industrial peat<br />

extraction, the<br />

process has accelerated<br />

and within a<br />

few decades most<br />

of the larger raised<br />

bogs in the Irish<br />

midlands will have<br />

been exploited.<br />

It is crucial<br />

that appropriate<br />

measures be put in<br />

place to promote<br />

the wise use of<br />

remaining peatland<br />

resources, to ensure<br />

that adequate<br />

43


pristine areas of high ecological value<br />

are identifi ed and conserved and that<br />

the extensive cutaway <strong>peatlands</strong> which<br />

remain following mechanical peat<br />

extraction are used in the best interests<br />

of society as a whole. Ireland is obliged<br />

under the terms of the Convention<br />

on Biological Diversity (CBD) to take<br />

account of ‘multifunctionality’ when<br />

considering the future development<br />

and use of cutaways.<br />

Also arising out of its commitments<br />

under CBD, Ireland has undertaken<br />

to carry out and implement local<br />

Biodiversity Action Plans which are<br />

currently being prepared on a county<br />

basis. In parts of Ireland where bogs<br />

are prevalent, <strong>peatlands</strong> will feature<br />

prominently in these plans. It is thus<br />

timely to explore and enhance awareness<br />

of the ecological value of <strong>peatlands</strong>.<br />

In short, Ireland needs to apply<br />

the principles of Wise Use of <strong>Peat</strong>lands<br />

stated in Joosten and Clarke. 1<br />

Knowing our <strong>peatlands</strong><br />

There is currently a considerable<br />

amount of scattered information on<br />

various aspects of the ecological, physio-chemical,<br />

socio-economic and policy<br />

issues regarding <strong>peatlands</strong> that need to<br />

be considered in the development of<br />

guidelines for sustainable management<br />

of <strong>peatlands</strong>. However, a much more<br />

extensive review and evaluation of this<br />

information is required and further<br />

Socio-cultural, economic & institutional/policy<br />

Biodiversity<br />

This work builds on the considerable<br />

body of existing information on vascular<br />

plant communities and macrofauna<br />

of Irish <strong>peatlands</strong>. Biodiversity is not<br />

limited to the ‘visible’ diversity present<br />

on the bog surface however. Soil and<br />

aquatic invertebrates together with micro-organisms<br />

(methanogenic archaea)<br />

are also a focus of the project, and for<br />

the fi rst time the signifi cance of this<br />

rich repertoire of Irish peatland biodiversity<br />

will be quantify and assessed.<br />

Characterisation of the<br />

physical peatland resource<br />

and its use<br />

An estimation of the volume and carbon<br />

content of peat is still required<br />

in order to improve estimates of the<br />

magnitude of the Irish peatland carbon<br />

reservoir. As well as producing maps,<br />

this project will examine the impact of<br />

climate change scenarios on the stability<br />

of the peatland carbon resource. It<br />

will examine peatland vulnerability to<br />

man-induced interferences (mining, afforestation,<br />

sheep grazing, wind farms)<br />

with respect to 1) physical aspects (risk<br />

of ‘bogslides’), 2) carbon and methane<br />

fl uxes, and 3) hydrological features.<br />

of <strong>peatlands</strong> within the Irish public in<br />

general and how the contribution of<br />

<strong>peatlands</strong> in social, economic and environmental<br />

terms can be characterised<br />

by indicators over time. This will be<br />

done through 1) the examination of<br />

communities linked to peatland areas,<br />

rural development, archaeology and<br />

culture and tourism; 2) the economic<br />

valuation of resource uses, market and<br />

non-market values including carbon<br />

sink, and 3) the appraisal of relevant<br />

policies. In addition, an in-depth case<br />

study will be carried out in an area<br />

largely dominated by industrial cutaway<br />

<strong>peatlands</strong> with a view to producing a<br />

blueprint on community and stakeholder<br />

involvement in the future of<br />

<strong>peatlands</strong>.<br />

Project activities<br />

The fi rst activity of the project was to<br />

set up a stratifi ed sampling programme<br />

representing all types of <strong>peatlands</strong><br />

found in Ireland. Four representative<br />

sites were identifi ed among the following<br />

categories: lowland/Atlantic<br />

blanket bogs, mountain blanket bogs,<br />

raised bogs and fens with cutaway<br />

<strong>peatlands</strong> forming an added category<br />

where certain studies will be carried<br />

out to supplement already existing<br />

projects. 2 Where possible, studies will<br />

be replicated in both ‘natural’ and ‘degraded’<br />

areas within the same peatland.<br />

This will help assessing the impact of<br />

activities such as turf-cutting and afforestation<br />

as well as considering the<br />

effects of restoration or rehabilitation,<br />

for example where drains have been<br />

blocked.<br />

The project is multi-disciplinary<br />

and brings together the expertise from<br />

different organisations around Ireland.<br />

The project also benefi ts from the<br />

contribution of experts from several<br />

countries through an international<br />

Recording the Past: the Power of <strong>Peat</strong><br />

<strong>Peat</strong> bogs are powerful archives<br />

containing records on<br />

the environment and culture<br />

of the past, such as climate<br />

change - as indicated by<br />

botanical remains - and bog<br />

finds such as archaeological<br />

materials, including human<br />

remains (bog bodies). Some<br />

recent research highlights<br />

from the Netherlands are<br />

presented.<br />

<strong>Peat</strong> bogs are growing continuously<br />

under certain climatic conditions such<br />

as those that prevailed during the<br />

Holocene - the present geological period<br />

that, following the last ice age, has<br />

lasted for approximately 11,500 years.<br />

<strong>Peat</strong> bogs and palaeoclimate<br />

By digging into terrestrial deposits, one<br />

travels, in general, back in time from<br />

the present to the past - the deeper,<br />

the older. The relative occurrence of<br />

plant species at a certain depth (and<br />

thus at a certain time in the past)<br />

indicates climatic conditions, like tem-<br />

Figure 2: The variations in the natural 14 C content, as measured in tree<br />

rings dated by dendro-chronology. The 14 C content is plotted as the<br />

deviation from the normal level, and is corrected for radioactive decay.<br />

perature and humidity, under which the<br />

plants at this depth were growing. In<br />

general terms, dominance of tree pollen<br />

is indicative of warmth; the relative<br />

abundance of different species gives<br />

fi ner detail. For example, there usually<br />

is a dominance of birch and pine during<br />

the initial phase of an interglacial<br />

like the Holocene, followed later by<br />

mixed forest (oak, elm, hazel) in the<br />

temperate regions. Thus, records of<br />

preserved botanical remains like pollen<br />

and macrofossils (branches, leaves)<br />

form a proxy for the palaeoclimate.<br />

<strong>Peat</strong> bogs consist of bog mosses<br />

(species of Sphagnum). They are<br />

rain-fed and grow continuously. After<br />

death, the mosses are well preserved.<br />

Continual growth of the peat bog surface<br />

and burial of dead organic matter<br />

leads to peat sequences that can exceed<br />

10 m in depth.<br />

Radiocarbon Dating<br />

The chronology of such deposits can<br />

be obtained by 14 C (or Radiocarbon)<br />

dating of organic remains like peat,<br />

macrofossils, or pollen. Radiocarbon is<br />

a natural radioactive<br />

isotope<br />

(with a half-life<br />

of 5730 years)<br />

of the element<br />

Carbon.<br />

This isotope is<br />

continuously<br />

produced by<br />

cosmic radiation<br />

in the<br />

upper atmosphere,<br />

and is<br />

taken up by<br />

the plants by<br />

photosynthesis.<br />

From there<br />

it fi nds its way<br />

into all living<br />

organisms via<br />

the food chain.<br />

There is an<br />

equilibrium<br />

Text and photos: J. van der Plicht<br />

J. van der Plicht.<br />

between uptake and decay of 14 C . After<br />

death of the organism, there is no<br />

longer uptake of 14 C; radioactive decay<br />

causes the content of 14 C to decrease.<br />

Hence, by measuring the remaining<br />

14 C content of for example the botanical<br />

remains from within a peat bog, the<br />

age of these remains (more precisely:<br />

the moment of death) can be established.<br />

The isotope 14 C provides in fact<br />

a clock, built into the organic residues.<br />

Although this sounds like a simple<br />

and straightforward principle, in practice<br />

there are many complications of<br />

which only one is mentioned here. For<br />

the simple dating model to work, one<br />

has to assume that the natural atmospheric<br />

14 C concentration is constant<br />

throughout time. It appears that this<br />

is not the case: the cosmic ray fl ux impinging<br />

on earth, and thus the amount<br />

of 14 C produced in the atmosphere,<br />

depends on factors like the strength<br />

of the earth’s magnetic fi eld, and solar<br />

activity.<br />

In addition, the 14 C concentrations<br />

are extremely small (1:1012-1015) so<br />

that measuring them requires highlyspecialized<br />

equipment, such as shown<br />

in Figure 1.


Trees as calendars<br />

The varying 14 C content in nature is<br />

known by a calibration curve, which<br />

is obtained by 14 C dating of tree rings<br />

from wood, that, in addition, are dated<br />

absolutely by dendro-chronology. This<br />

calibration curve makes dating possible<br />

because it allows the calculation<br />

of “historical ages” from “ 14 Cages”,<br />

thus taking the natural variations into<br />

account. The tree ring calendar extends<br />

back to more than 14,000 years<br />

ago. The calibration data are shown<br />

in Figure 2 as the relative 14 C content<br />

(corrected for radioactive decay) with<br />

respect to present day values.<br />

The long-term (millennium scale)<br />

trend of the data can be explained by<br />

the infl uence of the earth’s magnetic<br />

fi eld on the 14 C production rate. In<br />

general, this caused a higher 14 C content<br />

in nature millennia ago compared<br />

with the present. The sharp excursions<br />

on this long-term trend (like the one<br />

indicated at 800 BC) are caused by<br />

solar fl uctuations.<br />

At 800 BC, a climate change is registered<br />

in archives like peat bogs, known<br />

as the Subboreal-Subatlantic transition.<br />

This is illustrated in Figure 3, the peat<br />

bog Bargerveen in the Netherlands.<br />

The darker, more decomposed Subboreal<br />

peat was deposited under relatively<br />

warm and dry climatic conditions. The<br />

lighter coloured Subatlantic peat was<br />

formed under cooler, wetter climatic<br />

conditions. The change is marked in<br />

the fi gure, and is observed in many<br />

archives worldwide.<br />

Plant remains reveal past<br />

Botanical analysis of peat-forming<br />

plants from several peat bogs, in<br />

combination with precise 14 C dating,<br />

shows a remarkable phenomenon, as<br />

illustrated for the Engbertsdijksveen<br />

(the Netherlands) - see fi gure 4. The<br />

sharp rise of 14 C at 800 BC coincides<br />

with the shift from “older, darker” to<br />

“younger” Sphagnum peat at which<br />

point (see Figure 3) Sphagnum acutifolia<br />

shows a decline. Thereafter, following<br />

a dominance by highly hygrophilous<br />

moss species, Sphagnum cuspidatum and<br />

Sphagnum papillosum, the peat is formed<br />

mainly by remains of Sphagnum imbrica-<br />

Figure 1: The Accelerator Mass Spectrometer (AMS) for measuring 14 C concentrations at<br />

Groningen University, the Netherlands.<br />

tum, which has a preference for oceanic<br />

climatic conditions with a high air<br />

humidity.<br />

The wetter conditions around 800<br />

BC also coincide in signifi cantly rising<br />

water tables in the Netherlands, as<br />

evidenced by archaeological investiga-<br />

tions. The climate shift is observed on<br />

a global scale, and seems to be connected<br />

with migrations of prehistoric<br />

peoples as well. It is also remarkable<br />

that this time corresponds with the<br />

Bronze Age / Iron Age transition in<br />

Northwestern Europe.<br />

transition (indicated).<br />

The correlation of increased 14 C<br />

(which means solar infl uence), wet<br />

shift in peat bogs and climatic detoriation<br />

is also observed for the strong<br />

14 C excursions, observed during the<br />

so-called Little Ice Age (ca. 1600 AD;<br />

see Figure 2). In addition, the increased<br />

production of cosmogenic isotopes<br />

Figure 4: Variations in the natural 14 C content (see fi gure 2),<br />

zoomed in for 1000-500 BC. Also shown is a selection of botanical<br />

data from Engbertsdijksveen, the Netherlands. The sharp rise in<br />

the 14 C signal (a solar proxy) coincides with a climatic detoriation,<br />

as observed in a shift in Sphagnum species.<br />

48 PEATLANDS <strong>International</strong> 1/2006<br />

( 14 C, but also 10 Be) appears to be associated<br />

with cooler climate throughout<br />

the complete Holocene.<br />

It is important to note that the<br />

observed teleconnections are an indication<br />

that “solar forcing” of climate<br />

change plays a more important role<br />

than previously thought. The mechanism<br />

is still not understood,<br />

however.<br />

To extract palaeoclimatic<br />

information<br />

from peat bogs, a<br />

variety of research<br />

programs are implemented.<br />

As a good<br />

example, we mention<br />

the EC-funded project<br />

Accrotelm (Abrupt<br />

Climate Changes<br />

Recorded Over The<br />

European Land Mass).<br />

<strong>Peat</strong> bogs and<br />

cultural finds<br />

In the extensive peat<br />

bogs of Northwestern<br />

Europe, archaeological<br />

fi nds shed light on<br />

past cultures. Such<br />

fi nds mostly took<br />

place during the era of<br />

peat cutting. From the<br />

17th - early 20th century,<br />

peat was a major<br />

source of energy in Northwestern Europe.<br />

A fi ne example of an archaeological<br />

fi nd is shown in fi gure 5: a wooden<br />

bog road from the Neolithic (ca. 2100<br />

BC), found in the <strong>peatlands</strong> of Nieuw<br />

Dordrecht, province of Drenthe, the<br />

Netherlands. A mystery is that the road<br />

does not lead anywhere; the construction<br />

was stopped for some reason.<br />

Wooden wheels, shoes, stone tools,<br />

pottery, ornaments and even unique remains<br />

of a temple (Barger-Oosterveld)<br />

have surfaced from the peat during the<br />

cutting era, illuminating cultures of the<br />

past from the Stone Age, Bronze Age<br />

and Iron Age.<br />

Bog bodies<br />

The most dramatic fi nds are people<br />

- the well known bog bodies. These<br />

bodies are known from the peats of<br />

(mainly) Ireland, England, Germany,<br />

the Netherlands and Denmark. Unfortunately,<br />

many bog bodies did not<br />

survive their discovery very long. Quite<br />

a few were reburied; others were destroyed<br />

(or even powdered into a medicine:<br />

“mumia”). But several bodies did<br />

fi nd their way into museums. Some<br />

bog bodies were found in an excellent<br />

state of preservation, like the famous<br />

Tollund Man in Denmark. Others, like<br />

the Yde girl (fi gure 6a), were damaged<br />

during the peat cutting and decayed<br />

partly after their discovery, before conservation<br />

measures could be applied.<br />

The Yde girl is the most famous bog<br />

body of the Netherlands, perhaps because<br />

her head has been reconstructed<br />

(Figure 6b). The body was found in<br />

1897 near the village of Yde (province<br />

of Drenthe, the Netherlands). She obviously<br />

died through strangulation with<br />

a woollen band, still visible around her<br />

neck. Her age is established as 16 years<br />

old.<br />

Establishing the age of bog bodies<br />

was for a long time a major problem,<br />

as most of them came to light<br />

unaccompanied by objects that could<br />

be dated on the basis of typological<br />

evidence. In addition, 14 C dating is<br />

hampered by the prolonged “chemical<br />

treatment” of the samples by the<br />

peat acids. Recently, a large series of<br />

bog bodies were 14 C dated by systematic<br />

analysis of materials like clothing<br />

(fur, textile), skin, leather (shoes), hair,


Figure 5: Bog road (consisting of trees) constructed in a peat bog<br />

ca. 4100 years ago near Nieuw Dordrecht, the Netherlands.<br />

wood and bone (when available) using<br />

the equipment shown in fi gure 1. It appears<br />

that most bog bodies date from<br />

the Late Iron Age / Roman period (ca.<br />

2nd century BC - 4th century AD). For<br />

example, Radiocarbon measurements<br />

indicate that the Yde girl shown in fi gure<br />

6, dates between 40 BC and 50 AD.<br />

Final remarks<br />

<strong>Peat</strong> bogs are powerful archives of the<br />

past. Their botanical remains form a<br />

record of the ecological circumstances<br />

like climate. In addition,<br />

intriguing<br />

prehistoric cultural<br />

evidence came to<br />

light during the peat<br />

cutting era. This illustrates<br />

the old saying<br />

that “in order to understand<br />

the present<br />

one needs to understand<br />

the past”.<br />

The most spectacular<br />

archaeological<br />

fi nds are the bog<br />

bodies, several of<br />

which had been executed<br />

(like the Yde<br />

girl, but also Tollund<br />

man and others), as<br />

proven by strangulation<br />

ropes. Most<br />

archaeologists think<br />

that these bodies are<br />

offerings, but this<br />

remains speculation.<br />

It is certain, however,<br />

that the peat bogs did function as places<br />

to offer. There is no other explanation<br />

for the occurrence of many pots<br />

with valuable amber beads (sometimes<br />

thousands), and Nordic bronze musical<br />

instruments (lures) which are found in<br />

pairs in the peat and which must have<br />

been extremely valuable for prehistoric<br />

man.<br />

In terms of the palaeoclimate, peat<br />

bogs suggest that past variations in the<br />

activity of the sun have been important<br />

contributing factors for climate<br />

change. This issue - “solar forcing”<br />

of climate change - is now back on<br />

the scientifi c agenda, in addition to<br />

the more generally recognised “CO 2<br />

(greenhouse) forcing”. It is obviously<br />

crucial that the role of “solar forcing”<br />

be taken into account in evaluating the<br />

anthropogenic contribution to climate<br />

change of our planet. �<br />
