ECONOMIC AND ENERGETIC EFFECTS OF OCCURRENCE OF PORODEADEALA PINI IN NORTH-WEST POLISH FOREST STANDS

Keywords: Porodaedalea pini, wood decomposition, financial loss, heartwood
Abstract:

Introduction. Porodaedalea pini (Brot.) Murrill is a fungus in pine stands, where it is a permanent threat and causes significant losses of wood raw material.

Objective. The purpose of the work was to determine the size of economic losses in forest management re- sulting from the development of P. pini in pine stands, as well as to determine the calorific value of infected wood.

Methods. Field research was carried out in the area of the Forest Districts: Miastko, Tuczno, Gościno, Du- rowo and Łopuchówko.

Results. The percentage of wood with rot on the research plots ranged from 0.31 to 2.16, which translated into a financial loss at the logging area from 212.35 to 4315.31 PLN. It is estimated that in 2017, losses due to the occurrence of pine forests could amount to PLN 75 million. There was no decrease in the calorific value of the wood tested.
