The Apennine deciduous montane forests are a temperate broadleaf and mixed forests ecoregion in the Apennine Mountains of Italy. The development of these forests is ensured by the high rainfall in the Apennines (from 1000 mm in the southern mountains to 2500 mm in the north), combined with a temperate-cool climate. Because of climate change, the presence of silver fir (Abies alba), although still widespread, has been dramatically reduced in favour of beech.
