Age, species and site structure of forests within the Zielonka Experimental Forest district in 1963– 2014
Abstract
The aim of the study was to investigate changes in area and share of age classes, dominating tree species, forest site types that occurred in the course of fifty-one years within the area of the Zielonka Experimental Forest District and their connection with possible factors. The analysis of the observed changes was carried out with regard to their possible relations with the forest management and historical events in the area of the Forest District, described in succeeding forest management plans. It was found that the following events had the most significant impact on age, species and site structure of the forests within the Zielonka Experimental Forest District: grounds repossession; forestation of post-agricultural grounds (1963–1984); management system and type of cutting method, regeneration and introduced species; results of soil and forest sites analy- sis; conducting scientific research; biotic factors – occurring during certain periods; increasing surface of areas under the legal protection.
Keywords: age classes, dominating tree species, forest site types, area, share
