In all data-sets, quantitative data about dead trees and occurrence of wood decaying polypores was collected from randomly selected 0.5 hectare study plots. Above, total number of study plots (n) in each data-set is given in paranthesis after the name of the data-set. All field-methods are described on separate sub-pages.

Altogether the data-sets include 172 independent study plots and over 25 381 dead trees, of which 14 587 were over 10 cm in their breast height diametre. Data from two managed study plots in northern Häme is still missing from these figures.
