Logging-residue extraction does not reduce the diversity of litter-layer saprotrophic fungi in three Swedish coniferous stands after 25 years
Logging residues, consisting of branches and treetops, are increasingly being extracted for biofuel purposes in Fennoscandia, thereby decreasing the availability of fine woody debris (FWD). Little is known about the importance of FWD and litter to fungal diversity, although they constitute the major...

Logging residues, consisting of branches and treetops, are increasingly being extracted for biofuel purposes in Fennoscandia, thereby decreasing the availability of fine woody debris (FWD).
