Restoration of natural legacies of fire in European boreal forests: an experimental approach to the effects on wood-decaying fungi
Effective fire suspension in Fennoscandian boreal forests has caused a number of species to become threatened. To compensate for the negative ecological impacts of fire elimination, prescribed burning of forests as a restoration method has been introduced recently. We studied the effects of controll...
