Enemmän suomeksi!

The aims of the study are to: describe the relationships of polypore communities and forest structure in intact boreal forest landscapes, fragmented areas and forests with different management histories. analyse the effects that changes in forest dynamics cause to populations of wood inhabiting polypores. identify threshold levels of certain structures in boreal forests to allow survival of rich polypore communities. Methods: Analysis of polypore communities on randomly chosen study plots of 0.5 hectares in forests with different landscape and stand properties. Linkage of the species data to the data on forest and landscape structure and disturbance history. Analysis and modelling of species / host relationships.
