The paper compares the target species composition of Czech forests with the present one and creates four groups of areas with the largest and/or negligible differences between the target and the actual tree species composition using the Czech typology school. The area of coniferous trees is about 330,000 ha larger than is appropriate for the prescribed target tree species composition. There is a surplus of Norway spruce and Scots pine, and a deficiency of beech. Larch and other coniferous trees occupy a smaller acreage than they should according to the target tree species composition. There is also a deficiency of oak, maple and linden. On the contrary, the proportion of birch is larger than it should be, mostly because of replacing Norway spruce stands in polluted areas. A new programme has been developed to create ecologically stable and economically viable forests.
