 The interplanting of farm crops and trees, especially leguminous species. In semiarid regions and on denuded hillsides, agroforestry helps control erosion and restores soil fertility, as well as supplying valuable food and commodities at the same time. agro-foresterie |
1) Establishment of a new forest by seeding or planting of nonforested land. boisement2) The planting of trees on land which was previously used for other uses than forestry. 3) The planting of trees in an area, or the management of an area to allow trees to regenerate or colonize naturally, in order to produce a forest. |
The process of removing forest produce, particularly timber, fuelwood and bamboos, from its place of growth to some permanent or major delivery point, either for further transport or further manufacture, i.e. secondary conversion, or both. débardage |
The removal of forest and undergrowth to increase the surface of arable land or to use the timber for construction or industrial purposes. Forest and its undergrowth possess a very high water-retaining capacity, inhibiting runoff of rainwater. déforestation |
Forests have been exploited over the centuries as a source of wood and for obtaining land for agricultural use. The mismanagement of forest lands and forest resources has led to a situation where the forest is now in rapid retreat. The main aspects of the situation are: serious shortages in the supply of industrial wood; the catastrophic erosion and floods accompanying the stripping of forests from mountainous land; the acute shortages of fuel wood in much of the developing world; the spread of desert conditions at an alarming rate in the arid and semi-arid regions of the world; and the many environmental effects of the destruction of tropical rainforests. exploitation forestière |
The farming of trees to ensure a continuing supply of timber and other forest products. Foresters care for existing trees, protecting them from fire, pests and diseases, and felling where trees are overcrowded or dying and when ready for cropping. They also plant new areas (afforestation) and replant felled areas (reafforestation). pratique forestière |
Forests produce a range of products including firewood and charcoal, lumber, paper, and crops such as coffee, oil palm, and rubber. With careful planning of growth and harvesting, wood and other forest products are, in principle, renewable resources. But achieving renewability takes time - often decades, sometimes centuries. Without careful management, pressure for short-term exploitation can lead to tree removal, soil degradation, and conversion of woodland to other uses. Consumption of forest resources can lead to environmental problems as well as loss of critical habitat and species. production forestière |

impact de la sylviculture sur l'environnement
The world's forestry resources are shrinking at an alarming rate. The need for foreign exchange encourages many developing countries to cut timber faster than forests can be regenerated. This overcutting not only depletes the resource that underpins the world timber trade, it causes loss of forest-based livelihoods, increases soil erosion and downstream flooding, and accelerates the loss of species and genetic resources.

incendie de forĂŞt

-
inventaire des dégâts forestiers
Survey of a forest area to determine forest depletion. The aim of the inventory is to give an overview of the forest conditions. Especially should the inventory aim to detect any changes in the forest conditions, but it should also provide the distribution of the forest damages and find out any relation with site and stand conditions.

législation forestière

réserve forestière
Forest area set aside for the purpose of protecting certain fauna and flora, or both.
-
ressource forestière
Forest resources consist of two separate but closely related parts: the forest land and the trees (timber) on that land.
