DESCRIPTION
jbkTRANSCRIPT
The high demand for hardwoods world-wide usually leads to exploitation of the natural
timber, particularly in Africa, including Mozambique.
Frequently the practice is to fell the timber, export it as round log and walk away with the profits, giving no further thought to the
future of the forest.Logging in a sustainable manner although a long term project is not only possible but is being
successfully practiced on a concession in Sofala Province,
central Mozambique …..
Forest to Furniture
Logging in a sustainable manner
whereTCT-Dalmann Furniture, Lda.
Catapú timber concessionSofala, Mozambique
have been doing so for 19 years
Catapú in Sofala Province, central Mozambique, 32 km south of the Zambezi River
in Cheringoma District northwest of Inhamitanga Village
± S18° 00‘ 05'' and E35° 08' 13''
Introduction
• Concession = 30 000 ha.
• EN1 (main road) traverses the concession more or less on the watershed between the Zangue and the Tissadze Rivers
• 3,600 ha area with the sawmill, living quarters and
• M’phingwe commercial hospitality unit
•Altitude: at the Catapú turn-off from the EN-1 100 m a.s.l. 30 m.a.s.l. along the river valleys.

Core businessutilization of natural resources: felling 2 100 m³ of indigenous
hardwoods of various species
principally Panga-panga, (Partyshout) Millettia stulhmannii Taub.
Operation
Pod-mahogany, (Chanfuta)
Afzelia quanzensis Welw.
Wild-mango, (Mutondo)Cordyla africana Lour.
Based on a GERFFA (Gestao De Recursos Florestais E Fauna) inventory, concession divided into 30 blocks providing a 30 year cycle
20% to 25% mature trees left standing providing a timber resource for the second felling cycle and a seed bank for natural propagation and regeneration
Theoretically one block felled each year and after 30 years possible to return and fell again
In practice after 19 years only felling in block 17
1 000 ha Specially Protected Area around Zalula Pan
Planning • BLOCK DEMARCATEDblock boundaries planned to provide access roads with one road servicing two
blocksrecorded on multi-scaled electronic maps including drag lines, field loading
ramps and haulage roadsalso recorded existing roads and paths, waterways, steeply inclined terrain,
wetlands and spongy areasand including sites of religious or historic importance , nesting sites and animal
breeding burrows
• TREE INVENTORY trees to be felled carefully selected
– high yield potential – 40 or 50 cm dbh minimum
– minimum damage when falling- team 2 or 3 - GPS literate, good working knowledge of the forest and
familiar with the Integrated Forestry Inventories (IFI) system- day to day operations depend on conditions on the ground at all times taking
in account the impact on the forest
Felling- First cut 150 mm, two hand widths, above ground level- wedge-shaped for accurate log-fall- hinge in final cut to prevent kickback- Log cut into lengths both end of log and stump marked with the same number
Extraction
Commercially attractive branchwood is cut, dragged and ramped, awaiting “special authority” to move
it from the forest
Maximum recovery of timber essential!Traditionally left are second & third grade log + branchwood, + any dead or severely damaged trees Recovery increases usable volume by 20% to 25%.Mozambique forestry regulations prohibit logs of bark to bark diameter less than 30 cm & length less than 0,8 m being removed from the forest
HaulageMachinery restricted to small agricultural tractors with turn-table trailers & short-bodied rigid-chassis trucks.
.
Tractors with short coupled drag chains able to zigzag and manoeuvre between trees. Unnecessary to remove trees to access felled logs. Appearing haphazard and random, most successful way of moving logs with least possible damage to the forest
Drag lines linking fell-sites to in-field loading ramps are established using the line of least resistance
Moving the log manually
Loading the log
Hand or tractor loading results in minimum size ramps confined to small clear areas
No log transported for 24 hours after rain.
Timber cut into planks as required by the factory, dried in the kiln, sent to Beira to be made into high quality hardwood furniture
Adding valueTCT- Dalmann has sawmill and kilns at Catapú and furniture factory in Beira
• Maximum utilisation of commercially unviable sawn product -ultra shorts, blemished & mixed heartwood/sapwood planks. These are incorporated into a viable local industry with the construction of pre-fabricated houses, bee-hives and a range of turned products.

Very high priority
FOREST RESTORATION
The edge scuffled into the centre with a hoe and ........
Furrows created in drag lines repaired
.... gone over with a multidisc harrow. Abandoned ramps and haulage roads are harrowed and levelled
deciduous forest so disturbed ground soon becomes covered with fallen leaves
ideal medium for seed germination
1. Coppice and coppice management 2. Regeneration from seed
3. Baton planting
Regeneration
CoppiceDefinition: vegetation that resprouts after the trunk has been cut.
Coppice management is the most successful and rapid means of forest restoration at Catapú
When felling for timber the cut must be as low as possible for maximum recovery.the low clean cut on Panga-panga promotes a vigorous coppice growth giving optimum survival
Others produces better coppice growth when cut higher up as shown here with Mutondo which was cut illegally to collect honey
two or three strong shoots are selected from the explosion of coppice the first year and the rest removed. This reduces competition so the shoots flourish using the existing root system.
•After three years the coppice growth is deemed to be mature enough not to be threatened by new re-growth
Monitoring•Every stump visited and the coppice managed for three consecutive years
• Felled stumps are all numbered and the GPS position recorded
• The extraction infrastructure of drag-lines and access roads facilitates the location of all felled stumps.
New shoot eventually breaks away to form a new tree with it’s own root system
± 7 000 stumps are visited and dealt with every year. Now over 30 000 ‘surviving and thriving’.
Coppice shoots and saplings pruned after branching low down often grow upwards increasing the probability of a commercially viable tree
Coppice shoots survival rates:• Panga-panga ± 75--80%,• Chanfuta ± 40% • Mutondo ± 40%
In-forest restoration is carried out in areas disturbed by log extraction such as drag lines and abandoned ramps
alsoin areas previously damaged by fire or
subsistence agriculture
Seed• Seed collected throughout the year.• Selection, packaging, storage important.• Panga-panga & Chanfuta seeds scored and soaked for 24 hours before sowing. • Mutondo fruits have the flesh removed and are always planted fresh.
At the start of the rains:Seeds randomly scattered at a distance of about 1 m
Or Seeds deliberately planted
a few mm under the soil by hand, in a haphazard manner, at a distance of about every 1 to 1.5 m
along the harrow lines
In-field seeding
Plastic bags and seed beds prepared during winter Seed is sown in from mid-Sept to end DecTarget is 10 000 bags per year providing the main stock for reforestationLabour intensive but most successful method of regeneration from seed
Nursery seeding
Holes are excavated and filled with leaf litter
Start of the rainy season saplings planted out Basin surrounding the young tree filled with leaf litter as a moisture retaining mulch.
Replanting
Each year a “reserve” of about 4 000 plants is kept back to replace field mortalities. This is done during the dry weather with water planting. The theory being that these plants at ± nine months old, having established a firm root system, have been hardened and will survive and able to take full advantage of the annual rains and really get away.
Baton planting
± 1 m sections of branchwood cut and planted around the fell site from mid October through to end of December coinciding with the rising sap.
• This has not proved very successful.
Post planting & general management
Damage is caused by bushpig, baboons and antelope, namely suni and red duiker
Most damage by porcupines which are responsible for the greatest number of seedling and sapling mortality
Catapú gate made from sawmill off-cutsabout 1 m high
Catapú gate not only provides protection from animals but also offers partial shade and has the effect of making the tree grow upwards
Firethe biggest single threat to a forest and woodland
prevention using fire-breaks and cold-burns
Concession a mosaic with forest, thicket and open woodland often with grass.Controlled cool or cold burn undertaken during winter; only done in ideal conditions i.e. on a windless morning after a dew fall; produces a low intensity inefficient fire with minimal damage to established trees, burning mainly the overburden of grass in a mosaic pattern, leaving islands of grass and bush and forest where there is no grass untouched. Periodic winter rains produce a good flush of green grass which further reduces the risk of a hot fire later in the season. Different areas are burnt each year
Community
• Good relationship • Community projects• Reforestation• Fire paid services• Bee-keeping • Thatching grass • Bricks
• Felling logs correctly, transporting them to the sawmill with minimal damage is part of the core business of a timber concession. • Forest restoration and protections is not and therefore comes at a price, employing people on environmental work is purely an expense without them contributing to income at all.
• Environmental team = 9% of the total work force. • Expense of employing themOnly 3--5% of operational costs.• Therefore caring for the forest is not a financial burden. Benefit to the environment
is beyond measure!
