Book (stand-alone)Factors Affecting Productivity of Tropical Forest Plantations: Acacia, Eucalypt, Teak, Pine
GLOBAL FIBRE SUPPLY STUDY - Working Paper Series
1997Also available in:
No results found.Gains from a good tree improvement program (starting with species/provenance matching to site) can usually result in considerable gain in wood yields from tropical forest plantations. Optimal nursery and silvicultural practices (including seed pre-treatment, application of nitrogen-fixing soil micro-organisms, optimal spacing for defined end use, selection of adequate site, fertilization, and irrigation) can considerably increase such gains further. This report summarizes literature on gains tha t might be expected by implementing tree improvements and optimal silvicultural practices for acacias, eucalypts, teak and pines in tropical areas. Results are presented for each genus in turn, first examining factors common to all the genera, and then focusing on unique factors. The data on tree-growth gains are extremely variable from study to study. They range from virtually no favourable response to tree improvement and optimal silviculture, to gains of many hundreds of percent over c ontrols. This of course complicates the matter of using such data in global fibre supply modelling. -

No results found.In order to develop the forest sector, it is important to concentrate on the whole value chain, from forest management and to the ready products. Also, in order to increase efficiency and profitability of the wood use while reducing the pressure on the forests, it is necessary to utilize as much of the harvested wood as possible. This can be done e.g. by developing efficient use of other than the most commonly used tree species, by using different parts from the trees for different products, by using process residuals for specific products and by utilizing remaining residues as fuel. Often, an industry located relatively close to the forest can form a basis for new, small and middle-scale enterprises working on products other than the original industry’s, thus generating more workplaces. The more value that in this way can be added to the harvested wood, the more potential financing can be directed to forest management. This fact sheet tells about a good example of such development in the African sawmilling industry.
