Ilościowa charakterystyka zróżnicowania struktury borów sosnowych różnego wieku

Structure of 10 Scots pine stands in Nowe Ramuki Forest District was analyzed. The stands were of age from 25 to 220 years. Structure of pine stands younger than 115 years is characterized by low species diversity, low DHB differentiation and regular dispersion of trees. Stands older than 115−135 years show higher species richness, big diameter diversity and random dispersion of trees. Moreover, indices calculated for each stand show higher dispersion in older stands than in younger ones. Structure of old−growth pine stands is similar to natural stands of boreal zone.
