Dolgoročno dinamiko jelovo-bukovih gozdov v Sloveniji v treh prostorsko ločenih objektih (Leskova dolina, Trnovo in Jelovica) smo proučevali s podatki, ki smo jih pridobili iz gozdnogospodarskih načrtov in gozdarskih kart. Podatkovna zbirka GIS je obsegala podatke iz obdobja po letu 1897 za Trnovo, po letu 1899 za Jelovico in po letu 1912 za Leskovo dolino. Za analizirano obdobje smo ugotovili znatne spremembe proučevanih sestojnih znakov (debelinske strukture, lesne zaloge, raznolikosti debelinske strukture in drevesne sestave). Med objekti je različna velikost in usmerjenost sprememb sestojnih znakov. Nanje vplivajo mnogi dejavniki med pomembnejšimi so prejšnja raba gozdov, vpliv velikih rastlinojedov in rastiščne razmere. The long-term dynamics of silver fir-European beech forest stands in Slovenia were studied in three geographically dislocated study areas, Leskova dolina, Trnovo and Jelovica. In the study archival forest management plans and maps for the past century were used to create the GIS database. It included the data for the period after 1897 for Trnovo study area, after 1899 for Jelovica study area, and after 1912 for Leskova dolina study area. Substantial changes in diameter structure, stand volume, tree size diversity and tree species composition were documented, significantly differing between the study areas. Found stand dynamics were underpinned by a complex array of influential factors, among which past forest use, the impact of large ungulates and site conditions stood out.
