Germany's forests consist of 72 tree species. Of these, 26 nonconiferous
and 7 coniferous tree species are used economically.
The most important main tree species in this respect are
spruce, pine, beech, and oak. Among the coniferous trees,
larch and Douglas-fir play an important role in forestry in
general, while the silver fir is important in Southern Germany.
Regionally, high-grade non-coniferous trees such as ash,
maple, and cherry play an important role as well. Other nonconiferous
trees are hornbeam, birch, alder, lime, elm, poplar,
and Robinia or "locust tree" - all play a minor role in forestry.
Additional species include walnut, wild service tree, sweet
and horse chestnut, and a number of wild fruit trees.

The distribution of tree species depends on the quality of the
soil, the climate and other environmental factors. Thus,
forestry itself is responsible for the distribution of tree
species. This results in substantial amounts of ecologically
important and stabilized mixed forests in many locations.The
current ratio of non-coniferous to coniferous trees in forests
is 41 to 59 percent. Economically managed forests grow vigorously and are very resilient to cold- or extreme weather
conditions such as snow or storms. Less resilient species are
allowed more space and contribute to the development of
multi-species mixed forests that are less likely to succumb to
pests.
