A series of polypore inventories was carried out by the Helsinki team of mycologists in the strictly protected area of the Białowieża National Park in 2008–2012, followed by a polypore identification course and a tutorial published in 2013. The activity resulted in a substantial collection of herbarium specimens, images and georeferenced observation records of more than 140 polypore species, including a few species new to Poland. A number of specimens are now under taxonomic scrutiny as candidate species new to science. This traditional approach of revisiting the mycota of Białowieża was followed by a plot survey of polypores and of corticioids of all dead wood elements in 24 plots of 20 × 20 m, 12 plots inside and 12 outside the strictly protected area in different habitats. The fruit body data collected outside the reserve borders are being complemented by e-DNA evidences of the presence and abundance of wood-inhabiting species.
