<strong>COMMUNITY</strong> <strong>TREE</strong> <strong>PLANTING</strong> <strong>GUIDELINE</strong><br />

Sawlog Production Grant Scheme<br />

Supporting Tree Planting in Uganda Since 2003<br />

Tree planting is rapidly being recognised a viable investment opportunity by communities. In order to<br />

facilitate all those intending to enter this lucrative venture, the <strong>SPGS</strong> has prepared this community tree<br />

planting guideline. The guideline describes the various important steps you take in tree growing. Such<br />

stages include forest plantation planning, planting, maintenance and protection.


LAWLOG PRODUCTION GRANT SCHEME<br />

The Sawlog Production Grant Scheme (<strong>SPGS</strong>) has been helping people plant trees in Uganda since 2003. One<br />

of our goals is to educate people about the importance of trees in their community and guide them through the<br />

process of successful tree-planting.<br />

Franklin Delano Roosevelt once said “to exist as a nation, to prosper as a state, and to live as a people, we must have<br />

trees”. Research has shown this to be true. As a volunteer or professional, you are important to the health and well<br />

being of your community. You can lead the way to enhancing your community by organizing and implementing<br />

tree planting.<br />

Trees are a capital investment. They add to the economic and environmental well being of your community. Well<br />

planted trees are a source of income, would mitigate water run off, lower energy costs, reduce noise, sequester<br />

carbon and cleans the air, while replenishing the oxygen in the air we breathe.<br />

We designed this Community Tree Planting Guide to help you through the process of organizing and implementing<br />

a successful tree-planting project. It begins by assessing your planning site and concludes with long term care for<br />

your trees. Your project will be a lasting gift to your community while reflecting community development pride<br />

and spirit. <strong>SPGS</strong> is glad to support you in your efforts and we wish you success.<br />

Sincerely,<br />

1.0 INTRODUCTION<br />

This tree planting manual is one of the series<br />

of plantation guidelines being published by<br />

<strong>SPGS</strong> to assist private timber growers establish<br />

fast growing and high yielding timber tree plantations.<br />

It is a simplified and well illustrated manual aimed at<br />

meeting the huge demand for effective tree planting<br />

skills that are greatly lacking in the country. The manual<br />

is especially prepared for those whose objective is to<br />

plant trees mainly for timber and large poles. It can,<br />

however, serve those intending to grow trees for small<br />

poles and/or fuelwood.<br />

The manual guides you step by step through the important<br />

aspects of forest plantation planning, establishment,<br />

maintenance and protection up to harvesting the trees.<br />

Detailed information on each of these aspects can be<br />

found on other relevant <strong>SPGS</strong> plantation guidelines<br />

(listed in Appendix 2). People intending to grow trees<br />

for agroforestry<br />

purposes are<br />

advised to contact<br />

a g r i c u l t u r a l<br />

extension workers<br />

available at your<br />

Sub-county.<br />

1.1 Why<br />

plant<br />

trees?<br />

Tree plantations are<br />

a major source of<br />

wood for general<br />

c o n s t r u c t i o n ,<br />

especially housebuilding<br />

and<br />

making furniture like chairs, tables and many others.<br />

Besides increasing the value of your land as well as<br />

protecting it from encroachers, the main objectives of<br />

growing trees are often to produce timber and poles.<br />

Others are for fuelwood, charcoal, food for man and<br />

livestock, fertilizing and protecting soil, medicinal<br />

products and provision of shade for livestock and<br />

food crops. Trees are also often planted to beautify the<br />

landscape and purify or restore degraded areas.<br />

1.2 Which timber tree species<br />

are available for planting?<br />

Many indigenous (local) and exotic (introduced) tree<br />

species are available to grow in most parts of Uganda.<br />

However, if your objective is to plant timber trees as<br />

a business, its better you plant tree species with the<br />

following characteristics:<br />

• Those with reliable sources of high quality<br />

seed.<br />

• Species that have fast growth.<br />

• Species with desirable wood properties<br />

• Species suited to grow well on your planting site<br />

and<br />

• Species that grow well in a plantation situation.<br />

Many exotic tree species grow relatively faster than local<br />

ones and improved seed sources are often available.<br />

Moreover, the methods of establishing and maintaining<br />

them are well researched and understood. Examples of<br />

such exotic trees are Pines (Pinus caribaea and Pinus patula),<br />

Eucalypts (e.g. Eucalyptus grandis), Cypress (Cupressus<br />

lusitanica), Teak (Tectona grandis), Terminalia (Terminalia<br />

superba) and Hoop Pine (Araucaria cunninghamii).<br />

Some<br />

indigenous trees<br />

include Muzizi<br />

(Maesopsis eminii),<br />

Mahoganies<br />

(Khaya<br />

anthothica and<br />

Entandophragma<br />

spp), Mvule<br />

(Melicia excelsa),<br />

Prunus africanum<br />

and Podo<br />

(Podocarpus<br />

spp.). Because<br />

of their long<br />

maturity period,<br />

local trees can<br />

be preferably<br />

planted where the main objective is environment<br />

protection. Please refer to section 3.2 on species<br />

site matching described below to help you decide on<br />

which tree species to plant on your area.<br />

A well thinned Eucalyptus grandis plantation in South Africa (15 years old)<br />

So if your objective is to grow trees for timber and<br />

poles, it is now time to get started! Whether you intend<br />

to plant trees on small scale or on large scale, the<br />

recommended standards of tree planting should be<br />

followed to the end for the best results. It is essential<br />

to plan ahead carefully before you start so that you<br />

will not make any big mistakes and to ensure that you<br />

establish and maintain your trees properly to ensure<br />

they grow fast.<br />

2.0 PLANTATION PLANNING<br />

This is a first step that you have to do in order to be<br />

prepared for tree planting. You must first understand<br />

all the important steps (or activities) that you will have<br />

to undergo and when each of these activities should<br />

be carried out. Once you know these activities and<br />

the right time of doing them, it is easier for you to<br />

budget and look for all the resources needed ahead of<br />

time. on Your your plantation’s area. success depends on how well<br />

you time the required activities. As an example, let us<br />

assume that it is now January: you have land and you<br />

need to start planting Pine (Pinus caribaea) trees in the<br />

September rains. So you need to start planning!<br />

The common activities that you need to plan for<br />

include:<br />

Site survey, species selection (seed purchase, nursery<br />

preparation, seed sowing), clearing land, lining out,<br />

pitting, pre-plant weed control, planting, post plant<br />

weed control, and tree protection. The plantation<br />

calendar below helps to relate these activities with the<br />

best time at which they should be carried out. The<br />

need to start planning!<br />

shaded boxes show the month(s) in which you should<br />

carry out a particular activity in order to plant your<br />

trees in September.<br />

2.2 What is the best time to carry<br />

out the different plantation<br />

activities?<br />

As depicted in the calendar below, plantation activities<br />

are generally timed according to major rainy seasons<br />

in the country. In most parts of the country there are<br />

planted where the main objective is environment protection. Please refer to section on<br />

species site matching described below to help two you seasons decide - March/April on which and tree September/October.<br />

species to plant<br />

These seasons differ in duration of rains depending<br />

on your location. In some areas like Western Uganda,<br />

September/October is the longer rainy season, whilst<br />

2.0 PLANTATION PLANNING<br />

This is a first step that you have to do in order to be prepared for tree planting. You must<br />

first understand all the important steps (or activities) that you will have to undergo and<br />

when each of these activities should be carried out. Once you know these activities and<br />

the right time of doing them, it is easier for you to budget and look for all the resources<br />

needed ahead of time. Your plantation’s success depends on how well you time the<br />

required activities. As an example, let us assume that it is now January: you have land<br />

and you need to start planting Pine (Pinus caribaea) trees in the September rains. So you<br />

later than February and (if you have your own nursery)<br />

start nursery preparation in March. If you are buying<br />

your seedlings from a nursery, make sure it is one<br />

recommended by the <strong>SPGS</strong> nearby. With Pine (e.g<br />

Pinus caribaea), seed sowing should be done in May, to<br />

give pine seedlings 4 months to mature for planting in<br />

early September. If raising Eucalyptus grandis, however,<br />

3 months is sufficient - so sowing should be carried<br />

out in June. <strong>SPGS</strong> Plantation Guideline No. 7 – Tree<br />

Nurseries - is very useful and has more details).<br />

2.1 What are the activities that you need to plan for?<br />

The common activities that you need to plan for include:<br />

Site survey, species selection (seed purchase, nursery preparation, seed sowing), clearing<br />

land, lining out, pitting, pre-plant weed control, planting, weeding and tree protection.<br />

The plantation calendar below helps to relate these activities with the best time at which<br />

they should be carried out. The shaded boxes show the month in which you should carry<br />

out a particular activity in order to plant your trees in September.<br />

By around May (usually as the rains are ending), start<br />

mobilising labour for land clearing. This operation can<br />

run up to July to allow time for lining out and pitting<br />

in mid-August. The weeds must be controlled before<br />

planting the trees; otherwise they will take all the water<br />

and nutrients from the newly planted seedlings. Slash<br />

the weeds if necessary.<br />

2.2 What is the best time to carry out the different plantation activities?


LAWLOG PRODUCTION GRANT SCHEME<br />

Larger scale planters might want to use Glyphosate<br />

herbicide to spray the weeds before planting (N.B. if<br />

using chemicals, the staff must be properly trained and<br />

have safety equipment – see <strong>SPGS</strong> Plantation Guideline<br />

No. 16 for further details).<br />

In September when the soil is wet enough and the<br />

weeds are under control, the tree seedlings can be<br />

planted. Thereafter, the newly planted trees should be<br />

weeded when necessary and also protected from fires<br />

and from grazing animals. Remember that for proper<br />

tree planting business, people need to have the right<br />

skills for the right job, so make sure you have your core<br />

workers trained in plantation skills before embarking<br />

on major plantation activities. If this is not possible<br />

at your plantation, then hire a skilled labour from a<br />

neighbouring plantation for the beginning.<br />

Where land is limited like among the rural community,<br />

the following areas below can be utilised for tree<br />

planting:<br />

• Along the boundary with your neighbour.<br />

• Along the edges of your compound.<br />

• Along the sides of the main public road passing<br />

through your land or road leading to your home.<br />

3.1.3 Where should I not plant<br />

trees?<br />

A farmer should be aware that it is wrong to plant<br />

timber trees on the following areas:<br />

3.0 LAND PREPARATION FOR<br />

SUCCESSFUL <strong>TREE</strong> <strong>PLANTING</strong><br />

Once you are through with the work of planning,<br />

then you should now put your plans to work. This you<br />

do by undertaking site survey, species site matching<br />

(tree species selection), determining the right spacing,<br />

followed by land preparation and seedling planting as<br />

explained below:-<br />

3.1 Site Survey<br />

In site survey, you are interested in: 1) identifying the<br />

site where to plant the trees (and ensuring that the<br />

boundaries are clearly defined); 2) establishing the<br />

shape (lay out) of your plantation, dividing the area<br />

into smaller units (compartments) if necessary as you<br />

decide where the service roads or fire breaks will pass<br />

3) measuring the total area (in hectares) available for<br />

tree planting and 4) identifying areas to be protected<br />

such as wetlands and natural forests.<br />

3.1.2 Where can I plant my<br />

trees?<br />

All tree growers are advised never to clear an intact<br />

natural forest in order to plant trees. This is because<br />

the environmental and biodiversity values of a natural<br />

forest can not be replaced by tree plantations which<br />

are normally of just one species! Trees should only be<br />

planted in degraded forests or on other areas with few<br />

trees on. Remember trees like other food crops would<br />

prefer a fairly fertile land for best growth although<br />

most farmers often look for the poorest part of their<br />

land (including swampy areas) for tree planting.<br />

<br />

There is no timber tree that can grow on water even eucalyptus! These<br />

young pines have already started dying off.<br />

• On swamps or on areas that flood whenever it<br />

rains<br />

• Sites with intact natural forest cover should be<br />

conserved.<br />

• Any cultural site.<br />

• Land with unclear ownership.<br />

3.1.4 How do I lay out my<br />

plantation?<br />

Establishing the shape of your plantation requires<br />

you to walk through, and around the area where trees<br />

are to be planted. The objective is to enable you note<br />

the special features like swamps, rivers, hills, public<br />

roads, and many more that may be located within or<br />

neighbouring your area. Generally a plantation layout<br />

can be established as follows:-<br />

i. Mark the boundaries of your plantation, with<br />

corners clearly seen. Existing big trees or tough<br />

growing plants like sisal and Dracaena fragrans<br />

(Oluwanyi) can be used to mark corners.<br />

Community Tree Planting Guideline


LAWLOG PRODUCTION GRANT SCHEME<br />

ii.<br />

iii.<br />

iv.<br />

Establish a firebreak (5-15m) along the boundary<br />

to surround your plantation. If your plantation<br />

is surrounded by food gardens, make sure that<br />

after they are harvested, the drying vegetation is<br />

removed and placed at least 5m away.<br />

Where a clear public road, any permanent water<br />

body or a natural forest borders your plantation,<br />

these should form the firebreak.<br />

Decide on the spacing of your trees - which<br />

among others depends on tree species and<br />

expected final product<br />

For large scale plantations, much more can be done on<br />

the lay out. For example, the plantation area is divided<br />

into sub units or compartments (normally 25-30ha),<br />

which are separated by at least 8-15m wide spaces. The<br />

road network both internal and external is included<br />

which could be 5-8m wide.<br />

3.1.5 How can I determine the<br />

area of my plantation?<br />

You should know the size of your plantation so that<br />

you can estimate the number of seedlings needed for<br />

planting among others. Depending on whether your<br />

area is big or small the methods described below can<br />

serve as a guide.<br />

i. For small community woodlots that are normally<br />

1-2 acres, the area can be estimated by counting<br />

walking steps along two main directions. The<br />

number of steps taken along one corner of the<br />

plot is taken as length and the other as width. A<br />

walking step is approximated to be one metre.<br />

ii.<br />

iii.<br />

iv.<br />

If the area is approximately in the form of a<br />

square or rectangle, a long measuring tape can<br />

be used to measure the two sides of the area.<br />

One side is taken as length and other as width.<br />

Multiplying the two sides gives an approximate<br />

size of the area in square meters (m 2 ). This can<br />

then be converzted into hectares by dividing by<br />

10,000m 2 .<br />

Using Global Positioning System (GPS) which<br />

automatically computes the area in hectares<br />

after moving around the boundary of your<br />

plantation. GPS machines are still rare and thus<br />

the charges for their use may be high. They are<br />

recommended for big areas only.<br />

The district survey departments or private<br />

surveyors near to you can be contracted to<br />

demarcate your land.<br />

3.2 What is the right tree<br />

species to plant on my<br />

area?<br />

You can decide on which tree species to plant on your<br />

area by carrying out species site matching: this is the<br />

procedure undertaken to determine the most suitable<br />

tree species to be planted on a particular area. It is<br />

important that you ONLY plant trees that are most<br />

suited to your area. This is because only the best suited<br />

trees planted on an area will grow fast and mature early.<br />

In other words, the selection of the right tree species<br />

to plant on your area directly determines the success or<br />

failure of your plantation!<br />

3.3 What factors determine the<br />

type of tree species to be<br />

planted?<br />

In most cases, tree growth is affected by climate and<br />

soil conditions of the area. Other factors are the<br />

expected final products (targeted market), the nature<br />

of your land (hilly or flat), pest and disease threat. So,<br />

you can tell which tree species to plant on your area by<br />

looking at the following climate and soil conditions and<br />

comparing them with the various tree species growth<br />

requirements on table 1.<br />

a) Climate mainly rainfall and temperatures:<br />

• Rainfall amount and distribution. Basically areas<br />

that receive two long rainy seasons (at least 3<br />

months) per year are suited for most tree species<br />

like Eucalyptus grandis, Pinus patula, Pinus caribaea,<br />

Maesopsis eminii, Cupressus lusitanica and Araucaria<br />

cunninghamii. Areas that have only one long rain<br />

season per year like in northern Uganda are most<br />

suited for growing Pinus caribaea. Generally, areas<br />

along the cattle corridor like Mbarara, Mubende,<br />

Kiboga, Nakasongola, Teso and Karamoja regions<br />

which are usually dry should at the time being focus<br />

on planting the reasonably drought resistant Pinus<br />

caribaea until other appropriate tree species are<br />

available.<br />

• Temperature. Pinus patula is strictly restricted to<br />

cooler temperatures especially those in Kabale.<br />

If planted else where it will fail. Cool areas like<br />

Kabale, Fort Portal, Paidah, Mbale and Kapchorwa<br />

are preferred by Eucalyptus grandis and Cupressus<br />

lusitanica as well.<br />

• Trees tend to develop thicker or bigger branches at<br />

the expense of the main stem<br />

• Trees will be fewer and so you will have less trees<br />

to choose from during thinning<br />

• Increased weed growth (as they are exposed to<br />

light) will most likely increase fire risk on your<br />

plantation<br />

• Total volume production is reduced and<br />

• You catch less early money which people usually<br />

get from thinnings.<br />

3.4 What distance apart should<br />

I plant my trees?<br />

Having determined the right tree species for your area,<br />

it is now important that you get the right spacing to use<br />

on your area so that you order for the right number of<br />

seedlings. We strongly recommend planting your trees<br />

in lines, which makes everything easier later on – from<br />

preparing the planting pits to weeding after planting.<br />

The actual space (distance) between trees may change<br />

depending on type of tree species, quality of seed,<br />

and the availability of market for thinnings or small<br />

thinning).<br />

The standard spacing however for most timber trees<br />

including pines and Eucalypts of improved seed and<br />

good quality seedlings is 3m x 3m (10ftx10ft). Also 2.7m<br />

poles the spacing for Eucalypts can be reduced up to<br />

2m x 2m (6.6ft x 6.6ft). However closer spacing like<br />

2m x 2m brings in an early competition between trees<br />

3.5 Where do I get the seed/<br />

seedlings for planting?<br />

One of the determinants of your plantation success is<br />

the use of high quality tree seed or seedlings. Quality<br />

here mainly refers to whether the seed is an improved<br />

variety (i.e. has superior growth & timber characteristics<br />

and good health).<br />

3.5.1 Where do I get high quality<br />

seed?<br />

At the moment <strong>SPGS</strong> and NFA’s Namanve Tree Seed<br />

Centre are involved in importing improved seed from<br />

Australia, Brazil and South Africa for sale to private<br />

planters in Uganda. These are the current approved<br />

sources for seed orchard seed of Pinus caribaea var<br />

hondurensis (PCH) and Eucalyptus grandis. Trees from<br />

these improved seed sources will generally grow faster<br />

and straighter than locally collected seed. That is why<br />

you have to pay for their price!<br />

The impressive 3-year old demonstration planting of Pinus caribaea (Australian<br />

seed) at Kasagala Forest Reserve, Nakasongola. This is the result of careful planning,<br />

using only high quality seed, good land preparation and intensive weeding.<br />

Tree nurseries require much skill in establishment<br />

and management. You need properly trained and<br />

experienced nursery workers and constant supervision.<br />

Often many people have wasted money buying an<br />

expensive improved seed and they fail to raise seedlings.<br />

Therefore, unless operating on a large scale (say planting<br />

100ha/year) you are advised not to get involved in<br />

another complicated business of starting your own tree<br />

nursery. Small growers are thereby recommended to<br />

buy their seedlings from a recommended nursery near<br />

your area.<br />

3.5.5 What is the approximate<br />

price for high quality<br />

seedlings?<br />

Prices keep varying but as a guide, Pinus caribaea seedling<br />

cost ranges from 200-300 UShs. Whereas Eucalyptus<br />

grandis seedling is about 100-150/= each. Always book<br />

for your seed or seedlings six months in advance to<br />

planting time and be prepared to pay a 30% deposit.<br />

Having determined the right tree species to plant and<br />

also booked the right number of seedlings from a<br />

reputable nursery, the next activity to do is proper land<br />

preparation which includes land clearing, lining out and<br />

pitting as described below.<br />

Note; always be careful of the nursery you buy seedlings<br />

3.6 Preparing land for tree<br />

planting<br />

Land preparation involves activities that are carried out<br />

in plantation establishment to ensure that the land on<br />

which trees are to be planted is clear of any growing<br />

vegetation and to provide a well cultivated pit for the<br />

young seedling to grow well in.<br />

11<br />

Community Tree Planting Guideline


LAWLOG PRODUCTION GRANT SCHEME<br />

3.6.1 Why is it important to carry<br />

out land preparation before<br />

planting trees?<br />

It is necessary to first carry out land preparation before<br />

planting tree seedlings so as to increase the chance of<br />

survival and have rapid growth of the planted trees. By<br />

carrying out good land preparation your trees will not<br />

be out competed by weeds and also, the cultivation of<br />

the soil softens it to enable faster root penetration and<br />

faster seedling growth. Generally, well prepared land<br />

makes the later activities much easier to carry out too.<br />

3.6.2 What are the activities<br />

under land preparation?<br />

The common activities in land preparation include land<br />

clearing, lining out and pitting (digging planting holes).<br />

These activities should suitably be done during the dry<br />

season (June-July) before the more demanding activities<br />

of planting and weeding come in the wet month (in<br />

September/October). These activities are described<br />

below:-<br />

3.6.3 Land clearing<br />

This is the removal of vegetation (all non planted<br />

trees/shrubs and bush) existing on the site to be<br />

planted. However, thick forest land should never be<br />

cleared for planting trees. Only degraded forest land<br />

and grassland areas are recommended. Land clearing<br />

is often done manually using simple tools like an axe,<br />

panga and slashers combined with burning. Also on<br />

large scale by spraying with herbicides and using heavy<br />

machinery like bulldozer to cut, uproot and heap logs/<br />

stumps. Whichever method to use depends on existing<br />

vegetation and scale of planting, but steps taken in land<br />

clearing are;<br />

i. All the vegetation including grass and any none<br />

planted trees at the site must be cut down and<br />

left to dry. Trees should be cut as close to the<br />

ground as possible and big tree branches be<br />

chopped into smaller pieces.<br />

ii. All the grass as well as the chopped wood should<br />

then be gathered into small heaps spread on the<br />

site (preferably on stumps to get them burnt).<br />

iii. After heaping, they should then be set on fire<br />

preferably only on cool, non-windy conditions<br />

days and must be supervised. This should<br />

leave a clear open area ready for lining out and<br />

pitting.<br />

A well cleared site ready for lining out should not hinder visibility<br />

and movement<br />

3.6.4 What is lining out?<br />

This is the procedure taken to plant trees on straight<br />

lines at recommended spacing. The main reason of<br />

lining out is to ensure that the trees have enough space<br />

to grow while at the same time have some competition<br />

between themselves. This competition is important as<br />

trees grow to ensure that they produce straight stems<br />

with reduced branches. Other benefits of planting trees<br />

in lines are:<br />

- For easy accessibility or passage through the<br />

plantation.<br />

- Maintenance activities like weeding, pruning,<br />

thinning and harvesting can be contracted out<br />

to workers based on the number of trees or<br />

lines done.<br />

- For quickly estimating the number of trees or<br />

volume existing on your plantation.<br />

How do you line out? Lining out takes the following<br />

steps;<br />

1. Have a long rope of about 50m marked at<br />

intervals of the required spacing (say 3m)<br />

throughout its length. Stretch the rope along<br />

one side of the plantation site where planting is<br />

going to start. Now take that stretched line AC<br />

as your baseline.<br />

2. At each end of this baseline, mark off two cross<br />

lines (CE & AE) at right angles (90 o ) with the<br />

baseline (AC). This you do by measuring off<br />

first 3m starting from point C up to point B<br />

with your measuring tape. Next, measure off<br />

4m again starting from point C up to point D.<br />

Finally, if you measured distances CB and CD<br />

correctly, then distance BD is automatically 5m<br />

and angle BCD is 90 o (3,4,5 rule of the triangle)<br />

as shown on the diagram below.<br />

12<br />

Community Tree Planting Guideline


LAWLOG PRODUCTION GRANT SCHEME<br />

6. When the baseline has moved up to the end of<br />

the two cross lines, then steps 1-5 are repeated<br />

until the whole site is covered.<br />

Diagram showing 3,4,5 rule for marking cross line CE at right<br />

angle with the base line CA. Pegs are fixed into the ground at<br />

points BCD to hold tight the measuring tape before extending<br />

the lines to points A and E.<br />

3. Now, go and repeat this to mark off another<br />

cross line (AE) at right angle with the base line<br />

from point A. Cross line AE should now be<br />

parallel to cross line CE as shown on diagram<br />

below<br />

7. When lining out on steep slopes or hill (more<br />

than 20 o slope) it is important to do slope<br />

correction otherwise, the distance between<br />

trees will be lesser than expected. The same<br />

procedure of lining out as described above is<br />

followed. However, now the base line or cross<br />

line needs to be lifted up from the lower end of<br />

the slope such that its top end at point A is on<br />

the same height as its lower end at point B as<br />

shown by rope AC on diagram below.<br />

Now your cross line or base line should appear<br />

as shown by rope AC (3M) whose 3M mark<br />

C<br />

Diagram showing how to mark holes on the<br />

ground between cross lines CE and AE along<br />

direction ‘d’<br />

4. These two cross lines on both ends of the<br />

baseline should then be marked with the chosen<br />

spacing say of 3m intervals.<br />

5. After marking these two cross lines, the rope<br />

forming the baseline can now be kept moving<br />

up between the two cross-lines while stopping<br />

at each mark 2, 3-7 on the two cross-lines as<br />

directed by arrow ‘d’ above. As this rope is<br />

being shifted on the two cross lines, a person<br />

then keeps on marking planting holes on the<br />

ground by digging shallow holes corresponding<br />

to the spacing marks on the rope.<br />

13<br />

Lining out on a slope needs you to keep the cross line rope not on<br />

the ground level but be raised up at the same height as the upper<br />

end (A). A pole then can be used to locate the point (B) where the<br />

next pit down the hill should be dug.<br />

on the ground is determined by a vertical pole<br />

CB. Next, with your pole still at the same mark<br />

B, lower the rope AC to lie on the ground and<br />

hold it tight at both ends. You now find that the<br />

rope AC of 3M long when placed on the steep<br />

ground does not cover the full length AB but<br />

ends some where at point D.<br />

Therefore, measure length DB and add this<br />

to the spacing being used in order to get the<br />

true distance AB on the steep ground. If DB<br />

is 30cm or 0.3M then add it to our spacing of<br />

3M that is 3 + 0.3 =3.3M. This means all the<br />

trees on this particular slope should be spaced<br />

at 3.3m x 3.3m. In this case, the 0.3M is our<br />

slope correction factor. You can then mark your<br />

rope at 3.3m spacing.<br />

After successful lining out, the next step is to proceed<br />

to pitting.<br />

Community Tree Planting Guideline


LAWLOG PRODUCTION GRANT SCHEME<br />

3.6.4 What is pitting?<br />

Pitting is the process of digging pits and pits are the<br />

holes into which seedlings are planted. It involves<br />

enlarging the holes that were marked during lining out<br />

operation.<br />

How is pitting done:-<br />

• Use a hoe to remove the vegetation or any<br />

debris at each marked planting hole to produce<br />

a clean circle of 1 metre wide around it.<br />

• After having dug the soil out of the pit, break down<br />

the large soil clods and put the soil back to fill the<br />

pit.<br />

• You can then push in a small stick (about 1m long)<br />

into the centre of the pit so that when time for<br />

planting comes the workers do not only fail to see<br />

the pits but also be able to plant a seedling at the<br />

middle of pit.<br />

• When pitting is complete, a farmer is advised to<br />

wait until the area has received enough rainfall.<br />

Unfortunately, the little rain received during this<br />

period is enough to trigger germination of weeds.<br />

The best practice for larger growers is to carry out<br />

a pre-plant weed spray. Alternatively, do manual<br />

weeding just before planting. Never plant into<br />

a weedy pit: always keep the 1 m diameter circle<br />

around the tree free of weeds.<br />

3.6.5 Pre-plant weed control<br />

Margaret clearing a 1m diameter circle prior to digging a pit<br />

• Then dig a pit at the centre of the cleared area<br />

by enlarging the marked hole. This pit should<br />

be 30cm (1ft) wide and 30cm (1ft) deep. If the<br />

soil is hard like on rocky areas, you must still dig<br />

30cm deep and 30cm wide. In this case, use a<br />

pick mattock (Ensululu) to penetrate the hard<br />

soil. Dig the pit from different sides to ensure<br />

that the hole is as flat and wide at the bottom<br />

as it is at the top. Note also that 25cm deep and<br />

25cm wide pit is okay.<br />

When the area is wet enough for planting, the usual<br />

activity is to carry out a full cover herbicide weed spray<br />

of glyphosate to kill all newly germinated and growing<br />

weeds before tree seedlings are planted (pre-plant weed<br />

spray). Note that if using chemicals, people must be<br />

properly trained, well supervised and have appropriate<br />

protective clothing (refer to <strong>SPGS</strong> Guideline No.16<br />

- Safe Use of Glyphosate). After this spray is done<br />

planting can start the next day to allow seedlings to take<br />

an early advantage of growing free of weeds for some<br />

time before the next generation of weeds come up.<br />

NB: For the case of the communities, you can just cut<br />

all the vegetation down, either by the use of a hoe or by<br />

slashing before planting the seedlings.<br />

4.0 Planting Seedlings<br />

wide<br />

This is where seedlings are placed into the dug pits<br />

and carefully covered with soil. The planting process<br />

should be done so carefully that seedling roots are not<br />

bent and is placed to the right depth inside the pit.<br />

Only healthy and vigorous seedlings must be planted.<br />

Stressed seedlings should first be allowed to recover<br />

before planting. Seedlings can be stressed during<br />

handling and transportation to the planting site.<br />

When conditions are ready for planting, seedlings are<br />

transported to the plantation site. Depending on the<br />

care taken while loading, transporting and off loading<br />

of seedlings, their quality may be affected making them<br />

stressed or otherwise unfit for planting.<br />

4.1.1 In which ways can seedling<br />

quality be affected?<br />

Seedling quality is usually affected as a result of several<br />

handlings that occur when seedlings are picked from the<br />

nursery bed ground while loading them on containers<br />

then when being transported to the planting site. After<br />

reaching the site, again in the process of off-loading<br />

from the transportation containers to the ground some<br />

seedlings become affected. Generally, the seedlings are<br />

affected in these ways:-<br />

• Seedlings losing a lot of soil in their pots thus<br />

exposing their roots to dry up.<br />

• Mechanical damage by breaking seedling roots,<br />

leaves and stems.<br />

• Drying of seedlings due to long transport<br />

causing them to become stressed.<br />

Well packed seedlings on small designed containers like crates ready<br />

for transportation<br />

• Seedlings should be watered first before<br />

transporting to avoid excessive drying and soil<br />

loss.<br />

• Transport seedlings in the morning and evening<br />

to avoid hot day sun shine and shelter them<br />

from wind.<br />

• Offload seedlings at the planting site carefully not<br />

holding by their shoot, watered and temporary<br />

shaded. After the seedlings have recovered from<br />

stress which you can tell when their shoots stand<br />

upright they should be immediately planted.<br />

A young man off loading pine seedlings: Some seedlings have already lost<br />

soil and their roots are at a high risk of dying or being bent.<br />

Seedlings badly placed on the ground and also kept too long unplanted<br />

4.1.2 How can you minimize<br />

loss of seedling quality when<br />

handling them?<br />

• Seedlings should be packed on small designed<br />

containers like crates that are later packed on a<br />

car. If you have no containers yet, please let the<br />

seedlings be loaded upright on the car but not<br />

lying.<br />

4. 2 How to successfully plant a<br />

tree seedling<br />

Planting a seedling appears to be a simple process but<br />

basic mistakes are often made and more attention needs<br />

to be paid to the operation. Seedlings not planted well<br />

will grow poorly. For proper planting of a seedling the<br />

following procedure should be followed:-<br />

• Remove the stick once used to mark the hole<br />

during pitting process and dig a small hole<br />

15<br />

Community Tree Planting Guideline


LAWLOG PRODUCTION GRANT SCHEME<br />

into the centre of the planting pit. The hole<br />

should be deep enough to accommodate the<br />

whole root plug up to 2cm above root collar.<br />

If the hole is deeper than this then some soil<br />

should first be put back to reduce the depth so<br />

as to avoid burying the seedlings.<br />

• Shallow planting of seedlings is a common<br />

cause of early seedling deaths so ensure the tree<br />

is planted deep: it can be planted up to 2 cm<br />

above the root colar without a problem.<br />

• Once the hole has been successfully dug, the<br />

seedling is carefully stripped off its polythene<br />

bag, say by a razor blade. The polythene bag<br />

should not be thrown about but be placed on the<br />

container and later burnt near home. Seedlings<br />

must not be planted with polythene bags left on<br />

them as they will later die.<br />

• Next, hold the seedling in one hand (with its<br />

root plug lying half way your fingers to safe<br />

guard tap root) and place vertically into the<br />

hole deep enough too reach up 2cm above root<br />

colar level. Planting the seedling up to this level<br />

ensures that its root system is placed into the<br />

deeper cooler soil. Also the tree remains firm<br />

enough to resist wind bending even when the<br />

soft surface soil around it is washed away by<br />

rain.<br />

A seedling is carefully covered with soil and then firmed at its<br />

sides with hands but not foot<br />

• The seedling should then be properly firmed by<br />

palms of two hands ensuring that soil around<br />

the seedling is in level with the ground to avoid<br />

water collecting on the seedling. Do not over<br />

press or stump with your foot on the area closed<br />

to the seedling stem or heap the soil around the<br />

tree stem.<br />

A well planted pine seedling deep enough into<br />

the soil will be firm on the ground.<br />

A seedling (15-25cm tall) is carefully placed into the pit deep<br />

enough to be covered up to 2cm above root collar<br />

• Loosely cover the seedling with soil up to the<br />

2cm level above root collar. Remember while<br />

covering a seedling not to bend any of its bottom<br />

roots (tap root) that will lead to “J” rooting.<br />

easily be bent by strong wind or rain. It is also poor<br />

4.3 Beating up<br />

This is the process of replacing trees that have died<br />

or are not growing properly. This operation must be<br />

done within the same rainy season for uniform growth<br />

of all trees. For E. grandis beating up should be done<br />

at the end of the second week after planting, whilst<br />

for pines it should be no more than a month after<br />

planting (and in the same rainy season). Beating up<br />

can be minimised or prevented if the farmer carries<br />

out proper site preparation and planting because the<br />

survival percentage will be high (above 90%).<br />

Unfortunately, taungya for many years in Uganda has<br />

failed to produce good tree plantations, mostly due to<br />

people not caring for the trees but only for their food<br />

crops.<br />

It is necessary to first determine how many trees have<br />

survived before rushing to beat up.<br />

If only a few seedlings have died there is no need to<br />

beat up - after all some of the trees will still be removed<br />

during the thinning operation later on. To determine the<br />

survival percentage, one should inspect the plantation<br />

and make some counts as follows:<br />

Randomly walk along every 3rd row and count the 1st<br />

10 planting pits you come across. Record the number of<br />

both the dead and surviving plants on these 10 planting<br />

pits. Repeat the same procedure on the next 3rd row<br />

for at least 5 rows to cover a total of 50 planting pits<br />

(5x10). Add up the total number of seedlings that<br />

survived in the 50 planting pits and divide by the total<br />

planting pits surveyed (i.e.50). Multiply this by 100 to<br />

get the survival percentage as follows:<br />

No. of surviving seedlings/50 x 100 = Survival<br />

Percentage. If the survival percentage is 90% and<br />

above, do not worry about replacing the dead tress as<br />

long as the death is not on one location but spread all<br />

over the site However, if the survival falls within 70%-<br />

90%, replace the dead ones immediately. Survival of<br />

5.0 Maintaining Your Trees<br />

Once your trees have been well established, they must<br />

be properly maintained to grow well. The important<br />

management activities for maintaining plantations<br />

include weeding, pruning, thinning and protection from<br />

fires, animals and various other threats over their life.<br />

5.1 Weeding<br />

This is a regular activity carried out to ensure that trees<br />

are not competed out by weeds.<br />

5.1.2 Which methods can you<br />

use to weed trees?<br />

There are various ways of weeding as described<br />

below:<br />

Clean hoeing<br />

Hoeing is aimed at physically removing the weeds. All<br />

the weeds between the tree lines are dug out by hoeing<br />

and killed while weeds next to the tree are just up<br />

rooted to avoid damaging roots. This is a recommended<br />

method of weeding Eucalyptus trees.<br />

5.1.1 Why is it important to weed<br />

the trees well?<br />

To every farmer investing in tree planting as a business,<br />

you should aim at enabling your trees to grow as fast<br />

as possible without any competition from weeds.<br />

Consistent weeding enables trees to mature earlierand<br />

also to produce high quality trees which are big and<br />

straightand can be sold to give a high profit. Therefore,<br />

make sure you keep weeding your trees just like the<br />

way you do on food crops. Never allow weeds to grow<br />

more than half of your tree height, if you do, then your<br />

trees will not grow properly.<br />

Well weeded eucalypts trees. You can only get good profits from<br />

eucalypts by maintaining them under zero weeds<br />

Some trees, like the pines, can tolerate some little<br />

competition from weeds while others especially<br />

Eucalyptus is totally unable.<br />

Poorly weeded eucalyptus trees- No good results from such trees<br />

Poor weeding regime. Weeds are already taking advantage over<br />

the trees<br />

Young trees will grow much more quickly if all the<br />

weeds are removed by clean hoeing. This method is<br />

not cost effective (in terms of money and labour) on<br />

some tree species like pines, which can tolerate some<br />

competition from weeds.<br />

It also makes hilly areas prone to soil erosion and<br />

so farmers should not apply it to weed trees on hills<br />

instead, a combination of slashing with either spot or<br />

line weeding is recommended.<br />

18<br />

Community Tree Planting Guideline


LAWLOG PRODUCTION GRANT SCHEME<br />

Clean weeding of pine trees like this is the best but may be difficult<br />

financially on a large scale.<br />

Spot weeding<br />

In this method weeds (including food crops) are<br />

removed from a radius of 0.5m from the base of each<br />

seedling.<br />

Charles demonstrating to a farmer how spot hoeing is done<br />

Good spot hoed pine trees<br />

Spot weeding is normally carried out with a sharp<br />

hoe to scrape (do not to dig) the weeds away. Great<br />

care, however, must be taken in a 10cm radius area<br />

immediately around the young tree’s stem, where the<br />

young tree roots can easily be damaged. Put your thumb<br />

at the bottom of seedling stem and with your first finger<br />

widely stretched, make an arc round the seedling. Then<br />

now use your hand to up root all the weeds enclosed<br />

inside this circle. If a hoe is used instead of a hand,<br />

seedling roots will be damaged and then they die. It<br />

is only weeds on the 40cm radius circle that can be<br />

carefully scrapped off by a hoe. While removing weeds<br />

by a hoe, it is not advisable to dig deep to loosen the<br />

soil around the seedling because it disturbs it’s rooting<br />

system and also exposes the loosened soil into soil<br />

erosion and more heating.<br />

Line weeding<br />

A 1m wide strip along each planting line (0.5m from<br />

either side of each seedling) is clear weeded using<br />

hoes.<br />

All weeds within 10cm radius around the seedling must be constantly<br />

removed by hand to avoid destroying seedling roots. You can use a<br />

hoe to scrape off any weeds within the 40cm space. Weeds here should<br />

always be kept down as they compete directly with seedlings<br />

An excellent line weeding of young Pinus caribaea trees. Those weeds<br />

between trees should be kept shorter preferably by slashing or spraying<br />

19<br />

Community Tree Planting Guideline


LAWLOG PRODUCTION GRANT SCHEME<br />

If taungya is being practiced, line weeding is usually<br />

not suitable but rather use spot weeding.<br />

Slash weeding<br />

Weeds in the inter row space remaining after spot and/<br />

or line weeding can be cleared using sharp slashers.<br />

This slashing should be down to the ground if it is to<br />

be effective. Slash weeding and line weeding can be<br />

done in combination with spot weeding for controlling<br />

weeds on most trees like pines, Muzizi, Terminalia,<br />

Teak etc. Eucalypts should mostly be weeded by clean<br />

hoeing or herbicide spray until the trees themselves<br />

shade the weeds out.<br />

choose between weeds and trees. The use of herbicides<br />

for weed control by communities is discouraged on<br />

grounds of cost effectiveness and safety.<br />

5.1.3 Post-establishment<br />

weeding.<br />

This is the control of weeds in already grown up trees.<br />

Usually at about 2 years (Eucalypts) and 3 years (Pines<br />

etc) the trees will have well established themselves above<br />

the common grass and legume weeds. Usually at such<br />

a stage of tree growth, weeds are no longer a threat<br />

thus do not bother much to keep them weed free. Of<br />

most importance though is to keep monitoring your<br />

plantation for aggressive invading species like Lantana,<br />

Bug weed and Paper mulberry as well as the indigenous<br />

tree re-growth like Combretum SPP. These types of<br />

weeds normally form a bush in between trees and<br />

actively compete with trees and also block your safe<br />

passage. The growth of these weeds should periodically<br />

be controlled by chopping, up rooting/digging out or<br />

spraying with chemical to kill them. Otherwise, there<br />

should actually be no need to keep slashing short broad<br />

leaved weeds under grown up pines of 3 years and<br />

above.<br />

A good example of combining spot hoeing with slashing in pines. You<br />

are sure of getting high yields<br />

Where a farmer opts to grow Eucalypts, clean hoeing<br />

is a must. Always keep weeds out of competition with<br />

Eucalypts! Short of this; do not expect any good results<br />

to your investment. For most other tree species like the<br />

pines that resist some competition, a combination of<br />

slashing with either spot hoeing or line weeding can be<br />

effective but be on frequent basis till canopy closure.<br />

Herbicide spraying<br />

This is the most effective method used to weed<br />

commercial plantations. It is less labour intensive and<br />

kills weeds well if done by skilled people. Trees must be<br />

protected because the chemical (glyphosate) does not<br />

The trees that have already grown up like these no longer need constant<br />

weeding apart from selective cutting down of regrowing shrubs.<br />

Now as your well weeded trees continue growing<br />

faster because weeds are not competing with them, a<br />

stage reaches when trees themselves start competing<br />

especially for space and thus important operations of<br />

pruning and thinning should be done.<br />

A well sprayed tree plantation like this gives trees a chance to maximize their<br />

growth rates while still young.<br />

of tree lines and be 5m off any firebreak. Remember<br />

use of ordinary ladders as is commonly done is unsafe<br />

to both the tree and a person carrying out the work.<br />

3) How many trees do I need to leave on each hectare<br />

after first thinning?<br />

For our example of table 7 above, it is 750 stems<br />

per hectare<br />

4) How many trees should I leave on each plot after<br />

thinning?<br />

Number of trees to be left on each plot = 750 ÷<br />

44=17trees<br />

leave 17 trees needed per plot.<br />

NB1. The 8 trees to be removed also include empty holes<br />

(where trees died), bent trees, tree with branched tops in<br />

form of letter “Y” or any poor growing tree. Note that<br />

whether all trees are good the thinning should still be<br />

carried out to create more space within the remaining<br />

trees.<br />

The trees fit to be removed by thinning are (2) one – sided crown,<br />

(3) bole (trunk) deformed, (5) forked stem, (6) overtopped tree, (8)<br />

crooked stem, and (11) very small tree next to larger ones.<br />

NB2. If thinning is being carried out for sale the<br />

operation should be closely supervised to ensure that<br />

bigger trees do not end up being cut as a priority for sale.<br />

In this case, the objective of thinning as recommended<br />

in forestry will have changed.<br />

lose part or all of your year’s investment in one hour!<br />

To minimize fire risk on your plantation, observe the<br />

following fire protection measures:<br />

Firebreaks: These can be internal or external depending<br />

on size of your land. For community woodlots of 1-5<br />

acres, an external open area of at least 5m wide should be<br />

kept open around the trees. If the woodlot is bordered<br />

by gardens of food crops, then ensure that after their<br />

harvesting, the drying food crop remains should be<br />

removed 5m away from the trees. This strip of area<br />

should be kept open through slashing or hoeing before<br />

each dry season (June-August and December-Feb on<br />

average) until rains come back. As your plantation<br />

expands, internal firebreaks need to be included.<br />

Careful burning of crop gardens: While clearing adjacent<br />

land for food crops, make sure the rubbish is heaped and<br />

burnt in the middle of garden. Burning should be done<br />

during cool non windy conditions and should be closely<br />

supervised until you are sure the fire is completely dead<br />

before leaving the area.<br />

Timely weeding: Make sure that all your trees are well<br />

weeded during the rainy season such that in the dry<br />

season, there are no tall dry weeds that easily catch fire<br />

to burn your trees.<br />

More wide information concerning thinning can be<br />

found on <strong>SPGS</strong> Thinning Guideline No. 26.<br />

6.0 Protecting Your Trees<br />

Just like any other investment, you have to protect your<br />

trees until the recommended time to harvest or sell<br />

them arrives. Normally, trees are protected from fires,<br />

pests, diseases and animals.<br />

6.1 How do I protect my<br />

plantation from fire?<br />

Tree left to grow with a drying weeds like these do have a<br />

higher chance of being burnt down during the dry season<br />

A plantation with a good fire break between blocks<br />

Fire is one of the worst enemies of your trees. If you do<br />

not care to protect your plantation from fire you could<br />

Good relationships: Ensure you have good relations<br />

with your neighbours so they do not set your plantation<br />

on fire and can also be of assistance when called upon<br />

to help put off fire.<br />

NOTE: Get more information on Forest Fire Protection<br />

from Guideline No. 18.<br />

6.2 How do I protect my<br />

plantation from pests and<br />

diseases?<br />

Although there is no much threat so far regarding pests<br />

and diseases on trees being planted, it is important<br />

for the farmer to be vigilant about the health of their<br />

trees. You may not have the technical knowledge of<br />

controlling pests and diseases but you can contribute a<br />

lot towards the protection of your trees by periodically<br />

inspecting your trees checking on changes on the normal<br />

colour and health of leaves and stems. For instance<br />

when your tree leaves and branches start drying from<br />

top down wards that is commonly a sign of disease or<br />

pest attack.<br />

6.3 How do I protect my<br />

plantation from animals?<br />

Because it is your investment worth of millions, the<br />

farmer must protect the woodlot from browsing cattle,<br />

goats and other wild animals like antelopes, monkeys<br />

and bushbucks. These prefer shoots of young seedlings.<br />

They can also damage seedlings by stepping on them.<br />

Wild animals need to be constantly scared away, and<br />

clear any hiding places for them.<br />

Make sure you regularly inspect your plantation to check<br />

the above.<br />

Eucalyptus tree attacked by Blue gum Chalcid wasp<br />

For the case of Chalcid attack that is much worse where<br />

the trees are stressed like on poorly weeded trees or on<br />

those planted off-site in swamps or in rocky, infertile<br />

soils, the advice is to plant Eucalyptus on the right site<br />

and keep off weeds.<br />

For the case of termite attack you may notice some trees<br />

drying up and when you up root, you find its root system<br />

is already eaten off. For this case the first suspects are<br />

termites. If the area has many termite mounds then you<br />

have a higher risk of termite damage. Some farmers are<br />

using Dursban and Furadan to control termites but for<br />

their proper use, please seek professional advice. Always<br />

make sure your trees are growing vigorously by weeding<br />

them well and promptly. Report any strange occurrence<br />

of either a disease or pest on your plantation to an<br />

appropriate authority. These could be District Forest<br />

Officers, National Forest Authority, <strong>SPGS</strong> and Forest<br />

Research Institute.<br />

The unwanted visitors! Cattle like goats and other animals should be<br />

kept out of tree plantations because they eat the young trees<br />

Talk to your neighbour about his/her wondering cattle<br />

or goats and if problem continues report to LCs and get<br />

a lasting solution. Otherwise a charge per tree destroyed<br />

may be calculated based on its replacement value plus<br />

compound interest depending on the number of years<br />

the tree has spent.<br />

7.0 Harvesting And<br />

Replanting Tree<br />

Plantations<br />

Harvesting is the cutting of only mature blocks of<br />

trees when the best market for their sales exists. It is<br />

advisable to cut trees block by block as they mature<br />

depending on when they were planted. Remember that<br />

the most common rotation for trees is when they reach<br />

market size and not necessarily maturity. An appropriate<br />

harvesting system has to be designed according to the<br />

nature of the area of your plantation.<br />

24<br />

Community Tree Planting Guideline


LAWLOG PRODUCTION GRANT SCHEME<br />

7.1 What is the best time for<br />

cutting (selling) your trees?<br />

For Pinus caribaea, the recommended time is from 18-<br />

25 years. For other tree species, pleases refer to table 2<br />

(page 8). Your trees are like money put in bank to gain<br />

interest so that at some time in future you get more<br />

than the amount you banked. Likewise, as your trees<br />

grow each passing year, they keep on gaining more size<br />

(volume) until the recommended time of cutting them<br />

reaches. You get more money from a bigger tree.<br />

7.2 Why is it not advisable to<br />

cut/sell your trees too early or<br />

too late after maturity?<br />

It is not advisable to harvest trees before the<br />

recommended time, because they are still small in size<br />

(volume) yet are still actively putting on volume. More<br />

so, the wood itself is not mature enough to attract better<br />

price. On another hand, allowing trees to grow beyond<br />

the recommended time of harvesting (after maturity)<br />

is not good unless its a tactic to delay for best market,<br />

otherwise trees by this time are no longer growing<br />

actively and some may start dying of old age yet you<br />

still spend money to protect them.<br />

However, the most important point to note is that, you<br />

can sell your trees at any stage of their growth provided<br />

there is the best market offer for them. But you have to<br />

be careful of the fact that the best value of your trees is<br />

from big saw logs!<br />

7.3 Replanting of felled tree<br />

plantations<br />

After a given block is harvested, it should be immediately<br />

prepared for replanting in the forth coming rain season<br />

when is still free of weeds. Many of the trees like pines,<br />

musizi, or Terminalia are commonly propagated by seed.<br />

For most Eucalypts and teak that develop stems from cut<br />

stumps after harvesting, this re-growth (coppices) can<br />

only be used for fuelwood and small poles plantations.<br />

Eucalypt plantations that have been grown for timber or<br />

large poles must be replanted after harvesting and the<br />

coppice re-growth should be frequently cut or sprayed<br />

until they die off. The replanting is necessary because<br />

many of the trees will have been cut down at various<br />

stages of thinning and any re-growth from such stumps<br />

will have been suppressed by shade from the remaining<br />

trees leading to less stocking.– refer to Guidelines No.<br />

9,10 & 21 on growing eucalypts.<br />

8.0 Plantation Record<br />

Keeping<br />

There are some records that are particularly important<br />

for a tree farmer to safely keep for accountability and for<br />

future reference. Such records among others include:<br />

1) Nursery records<br />

Information on tree species, seed origin, date sown,<br />

amount sown etc.<br />

2) Plantation compartments records like;<br />

• Compartment identity (Name or number etc)<br />

• Compartment size<br />

• Planting details (tree species, date planted,<br />

spacing, survival etc)<br />

• Weeding status<br />

• Pruning plan<br />

• Thinning plan<br />

• harvesting plan<br />

3) Pest, disease and fire outbreaks<br />

4) Tools and equipment stores<br />

5) Expenditure and revenue<br />

6) Weather records (Only for commercial<br />

planters) and<br />

7) Map (s) of the area.<br />

However, for the community planters, the above records<br />

are not necessary. Only an activity register showing what<br />

is planned to be done and what has been completed is<br />

enough. The time when each activity is done should be<br />

recorded. For instance when you planted your trees.<br />

25 Community Tree Planting Guideline


LAWLOG PRODUCTION GRANT SCHEME<br />

APPENDIX 1<br />

<strong>SPGS</strong> COMMERCIAL AND <strong>COMMUNITY</strong> SUPPORT<br />

What is <strong>SPGS</strong>?<br />

The Sawlog Production Grant Scheme (<strong>SPGS</strong>) is a European Union funded programme that aims to promote<br />

private investment in timber production in Uganda. The <strong>SPGS</strong> started in 2003 and in just four years has subsidized<br />

around 7,500 hectares of commercial plantations throughout the country: this includes small community-based,<br />

tree planting associations up to large-scale commercial plantations. The current project runs until the end of<br />

2008.<br />

What is <strong>SPGS</strong> commercial support?<br />

This is a kind of support where private timber growers planting from 25 ha to 500 ha are provided with a subsidy<br />

of UG Shs. 600,000/= (Six hundred thousand shillings only) per hectare of well planted and managed trees.<br />

The land for planting can either be private or government land (CFR) as long as there is proof of ownership.<br />

(More details on investing in commercial timber production and <strong>SPGS</strong> can be got from Guidelines number 1 &<br />

2 respectively).<br />

What is <strong>SPGS</strong> community support?<br />

This is a support given to individuals in a community that may not have big chunks of land but are interested in<br />

tree planting business. There are two types of such communities;<br />

a) Where the individuals in community have reasonably larger areas of land that can collectively add up to at least<br />

25 ha, they are also encouraged to apply to the <strong>SPGS</strong> for the planting subsidy as a legally registered group. One<br />

excellent example of where this is working extremely well is Kamusiime Memorial Rural Development Association<br />

in the hills of Bushenyi, western Uganda. They are a group of 22 landowners who applied formally to the <strong>SPGS</strong><br />

in 2003, having pooled their land to make a total of 100 ha. By the end of 2006, Kamusiime had planted all 100<br />

ha with Pinus caribaea var. hondurensis – a species well suited to the hills there. Do not forget that <strong>SPGS</strong> payment is<br />

only made after you have planted trees and weeded them well. So you need a start-up capital for buying seed and<br />

planting.<br />

b) For the rural poor communities that have smaller pieces of land (up to 5ha) the project’s approach is slightly<br />

different. In this case, <strong>SPGS</strong> support is not a subsidy but is mainly by providing high quality seedlings and technical<br />

advice throughout the establishment period. The community contributes by preparing the area for planting well,<br />

planting all given seedlings immediately and thereafter promptly weed and protect trees.<br />

Preference will be given to communities that are registered organisations or associations living adjacent to either<br />

natural high forests or commercial tree plantations. A community that can be supported by <strong>SPGS</strong> should bare the<br />

following:<br />

• Be committed to tree planting according to <strong>SPGS</strong> standards<br />

• Have members preferably located within a single village for easy mobilisation and monitoring.<br />

• Have 20 interested members as a minimum<br />

• The minimum area supported for each member is one acre and maximum is 5 acres. This land can be<br />

private or on Central Forest Reserves.<br />

Any community which meets the above conditions can then apply in writing indicating within the application the<br />

following:<br />

• Clear administrative structure (showing names and titles of leaders)<br />

• The names of all community members<br />

• The area/size of land for each member<br />

• Estimated number of seedlings required by each member<br />

• If the community is legally registered, a copy of the registration certificate and a constitution should be<br />

attached.<br />

• Communities which are not legally registered are encouraged to constitute themselves into formal<br />

associations with elected leaders.<br />

• Provide both proper physical address (village, parish, sub-county, county and district names) and contact<br />

address showing; Post office number and at least two Telephone contacts, as well as e- mail or fax number<br />

if available.<br />

Once the application letter has been received, it will be studied and a formal reply sent to the community. This is<br />

then followed by a visit by <strong>SPGS</strong> team to appraise and train the community on tree planting standards. Following<br />

this appraisal as well as office evaluation, a community is finally informed whether it is successful or not. Successful<br />

communities are then supplied with seedlings at the beginning of the forth coming rain season. Note that once<br />

<strong>SPGS</strong> has committed itself to support a given community, it will continue to do so for as long as that community<br />

keeps up with the tree-planting standards described in this guideline.<br />

NOTE: <strong>SPGS</strong> further community support beyond this phase is subject to the availability of more funds.<br />
