Abstract:Poznavanje razvoja dominantnega drevja je pomembno za spremljavo razvoja enomernih sestojev, določanje režima redčenj, ciljnih premerov drevesnih vrst in optimalnega razmerja razvojnih faz ter ocenjevanje produkcijske sposobnosti gozdnih rastišč. S podatki stalnih vzorčnih ploskev smo analizirali debelinsko in višinsko rast dominantnih dreves petih drevesnih vrst kisloljubnega bukovja z rebrenjačo (smreka, bukev, graden, rdeči bor in kostanj). Za vrste smo ocenili rastiščni produkcijski indeks (SPI), ki je dominanta višina drevja pri prsnem premeru 45 cm, rastiščni indeks (SI) in prikazali postopek določanja optimalnega razmerja razvojnih faz glede na drevesno sestavo sestojev ter odločitev o ciljnih premerih drevja in pomlajevanju sestojev. Vrednosti SPI za bukev, smreko, graden, rdeči bor in kostanj so 28,4; 31,1; 25,1; 26,1 in 23,2, vrednosti SI pa 27,9; 32,5; 20,9; 22,9 in 21,7. Optimalni deleži razvojnih faz so odvisni od izbrane drevesne sestave gozdov ter odločitev glede ciljnih premerov in pomlajevanja sestojev. Model debelinskega priraščanja bukve kaže, da na njeno debelinsko rast pozitivno vplivajo prsni premer, produktivnost rastišča in raznomernost sestojev, negativno pa delež bukve v sestoju, sestojna temeljnica in naklon terena.

Title:Knowledge on dominant trees is important for forest planning: acidophylus beech forest type with deer fern as a case study
Abstract:Knowledge on the development of dominant trees is important for forest management, especially for determining thinning regime, target tree dimensions and optimal proportions of developmental phases of forest stands. Based on data from permanent sampling plots of Slovenia Forest Service we analysed diameter of height growth of individual dominant trees of five different tree species in acidophilus beech forest type with deer fern (European beech, Norway spruce, sessile oak, Scot pine and sweet chestnut). Based on the models, the site productivity index (SPI), defined as the dominant tree height at a diameter of 45 cm, and site indices (SI) of five tree species were determined, and procedure for optimal model of developmental phases in regard to tree species composition, target tree dimension and regeneration period was developed. SPI of beech, spruce, sessile oak, Scot pine and sweet chestnut amounted to 28.4, 31.1, 25.1, 26.1 and 23.2, respectively, while site indices amounted to 27.9, 32.5, 20.9, 22.9 and 21.7. The optimal model of developmental phases depends significantly on tree species composition of forest stands and management decision on target tree dimension and regeneration regime. Individual diameter increment model of dominant beech trees showed that tree diameter, site productivity and stand heterogeneity positively influences diameter growth, while proportion of beech in a stand, stand basal area and inclination had a negative impact.
