 9.4 km² of the Schönberg massif (which is in total 24 km²) and 3.4 km² of the actual mountain are covered with forest.The dominant tree of this mixed deciduous forest is the copper beach, but due to the many different types of soil and the local climate there are many different forest communities, as well as monocultures.Mainly beeches and silver firs grow in the deep and damp soil and form a dense canopy .
