HEALTH CONDITION OF SELECTED SCOTS PINE STANDS IN SZCZECINEK FOREST DISTRICT

Journal Title: Zarządzanie ochroną przyrody w lasach - Year 2015, Vol 0, Issue 1

Abstract

The aim of the study was to determine the health condition of selected Scots pine stands in Szczecinek forest district. Observations were carried out in 2014 on 15 permanent research plots, located on two types of forest habitat (BMśw and LMśw) on forest land and former farmlands, representing the age class II to VI. The evaluation of the damage to the crowns has been carried out on the basis of the bioindication method, which is based on three criteria: defoliation, the number of needle age–groups and type of tree crown attenuation. The analysis of health condition showed that 72.2% of the researched stands were damaged to the lesser extent, as they were qualified to the 0 and I degree of damage. The strong and total degree of damage has not been found. The average loss of assimilation apparatus was 19.56%. The stands growing on the forest land are characterized by a lower average defoliation of tree crowns (18.19%), while the loss of assimilation apparatus on land previously used for agriculture amounted to 20.82%.
