Abstract


An investigation carried out in the Western Carpathian Mountains (Ujsoły, Węgierska Górka, Ustroń and Wisła Forest Districts) demonstrated a strong relationship between dieback in Norway spruce stands and the intensity of occurrence of Armillaria ostoyae. For the most endangered site types – mountain deciduous forest (LG) and mountain mixed forest (LMG), analyses of losses of annual volume increment and of stand productivity were performed, and their financial dimensions determined. The greatest losses – of about 8 m3/ha/year for tree stands of the age of 100 years, and 400 m3/ha for the rotation period – were found for LG (Mountain broadleaved forest) site type.
