The Apennine deciduous montane forests, a temperate broadleaf and mixed forests biome, are an ecoregion in the mountain ranges of italian peninsula including the Apennine Mountains. The development of these forests is ensured by the high rainfall Apennines (from 1000 mm in southern Apennine to 2500 mm in northern Apennine), combined with a temperate-cool climate. Because of climate change, the presence of Silver Fir (Abies alba), although still widespread, is dramatically reduced in favor of the beech.
