Fungal diversity on decaying beech logs – implications for sustainable forestry

摘要: An analysis of factors influencing the diversity macrofungi fruiting on decaying beech logs at site level is presented. Variables related to log size and shape decay stage were found explain up 56% variation in total species richness 42% threatened (red-listed) species. Inclusion variables relating vernal flora degree soil contact further increased explained 71%, but these non-significant with respect red-listed However, inclusion variable type, distinguishing uprooted logs, broken root neck 1–7 8–15 m above ground, amount 50%. Among variables, number bole forks was superior describing both richness. Accordingly, forked trees should preferably be selected for order improve biodiversity, since they support comparably higher than unforked have limited economical value. The importance type appears connected occurrence certain non-dominant primary decayers, causing heart rot, subsequently allowing establishment it suggested that a high decayers may key conservation wood fungi. Microclimatic effect fruit body studied logs; however, microclimatic regime discussed as an important factor relation management dead fungal biodiversity.
