<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 />

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 />
x 2.7m (9ft x 9ft) is frequently used. But if planting next<br />
to where there is high demand for small construction<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 />
and so a farmer must be aware and be prepared to cut<br />
down many of them during first thinning operation to<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 />

price for high quality<br />
seedlings?<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 />

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 />

transportation to the<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 />

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 />

This pine seedling is not planted deep enough & can<br />
easily be bent by strong wind or rain. It is also poor<br />
quality seedling as it lacks a leading stem<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 />

not to peel down the tree.<br />
Note: all pruned branches must be piled in the middle<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 />
Any ladder used should be well designed to be firm on<br />
the ground as well as on the tree.<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 />

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 />

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 />
