The wood-inhabiting fungal community on standing dead birches : a comparison of ring-barked and naturally dead trees
Dead wood is an important part of forest ecosystems, especially since so many organisms depend on it for nutrients or as substrate for breeding or foraging. Since forestry intensified in northern Europe during the mid 1900s, the amount of dead wood in Fennoscandian forests has drastically decreased....

Dead wood is an important part of forest ecosystems, especially since so many organisms depend on it for nutrients or as substrate for breeding or foraging. Since forestry intensified in northern Europe during the mid 1900s, the amount of dead wood in Fennoscandian forests has drastically decreased. For wood-inhabiting organisms such as fungi, this has led to changes in the community composition with many species becoming rare and threatened by extinction.
