nåleskov coniferous forest (A forest type characterized by cone-bearing, needle-leaved trees. They are generally, but not necessarily, evergreen and relatively shallow-rooted. Since they grow more rapidly than most broad-leaved trees, conifers are extensively planted as a source of softwood timber and pulp. They are tolerant of wide-ranging climatic conditions, of many different types of soil and of considerable differences in terrain. Thus, they are found from the polar latitudes to the tropics, on most types of soils (especially, thin acid soils) and from mountain summits to coastal environments)
nåletab defoliation (1. The drop of foliage from plants caused by herbicides such as Agent Orange, diuron, triazines, all of which interfere with photosynthesis. The use of defoliants, as in Vietnam or in jungle clearance for agriculture, can permanently destroy tropical forests. Once the tree cover is removed, the soil is subjected to erosion and precious nutrients are rapidly leached away. 2. Destroying (an area of jungle, forest, etc.) as by chemical sprays or incendiary bombs, in order to give enemy troops or guerilla forces no place of concealment)
