Abstract
The paper presents results of observations of Scots pine tree crowns carried out in 2002 in the Sokolniki working circle of the Przedborów Forest Division. The evaluation comprised the total of 500 trees growing in pine stands of the IIIrd and IVth age class selected on the basis of investigations conducted on experimental surfaces with 25 trees from the main stand. It was found that the condition of crowns was either unsatisfactory or warning and this could be attributed to the local emitter of contaminations, i.e. the “PROSPAN” Chipboard Plant in Wieruszów.
