Abstract

Na podlagi preteklih meritev v obdobju od 1962 do 2017 smo na raziskovalnih ploskvah na nekdanjih novinah v katastrski občini Koprivni izračunali debelinske, višinske in volumenske prirastke za najpomembnejši drevesni vrsti - smreko in macesen. Na teh raziskovalnih ploskvah, ki so bile prepuščene naravnemu razvoju, so srednje temeljnični premeri manjši, število dreves pa večje od tistih v primerljivih gospodarskih gozdovih. V zadnjih tridesetih letih se je zaradi visokih sestojnih gostot zmanjšalo debelinsko priraščanje dreves smreke in macesna. Z dendrokronološko analizo priraščanja smreke in macesna smo ocenili vpliv klimatskih dejavnikov na priraščanje smreke in macesna. Na podlagi dendrokronološke analize smo ugotovili, da se leta z negativnim odzivom dreves v debelinskem prirastku od leta 1984 pojavljajo pogosteje.

Secondary title:	Growth of Norway spruce (Picea abies (L.) Karst.) and European larch (Larix decidua Mill.) on former slash and burn farming areas in Koprivna
Secondary abstract:	Based on past measurements from 1962 to 2017 on the forest research plots, located in the former slash-and-burn farming areas in the cadastral community of Koprivna, the diameter and height increments as well as volume increments of the two major species - spruce and larch - were calculated. Those set-aside natural research plots have a smaller quadratic mean diameter. The number of trees, however, is higher than in the comparable managed forests. Due to the high-density tree stands in the last thirty years, the spruce and larch trees radial has decreased. In order to determine the impact of environmental factors affecting spruce and larch radial growth, dendrochronological analysis was conducted. According to the dendrochronological analysis of the radial increment of trees the number of years with a negative response has been higher since 1984.
