Plants and animals include those generally common to Central Europe. According to the National Forest Inventory, beeches, oaks, and other deciduous trees constitute just over 40% of the forests; roughly 60% are conifers, particularly spruce and pine. There are many species of ferns, flowers, fungi, and mosses. Wild animals include roe deer, wild boar, mouflon (a subspecies of wild sheep), fox, badger, hare, and small numbers of the Eurasian beaver. The blue cornflower was once a German national symbol.
