20.500.12556/RUL-162611 Fitocenološka analiza gozdne vegetacije severnega pobočja Vancovca Phytosociological analysis of forest vegetation on northern slope of Vancovec Nad Železniki na severnem pobočju Vancovca smo z uporabo standardne srednjeevropske fitocenološke metode naredili 27 fitocenoloških popisov gozdne vegetacije. Uvrstili smo jih v štiri asociacije: Homogyno sylvestris-Fagetum Marinček et al. 1993, Galio rotundifolii-Abietetum M. Wraber 1959, Lamio orvalae-Fagetum (Ht. 1938) Borhidi 1963 in Lamio orvalae-Aceretum pseudoplatani P.Košir & Marinček 1999. Popisi so si bili med sabo dokaj podobni, zato je bilo uvrščanje oteženo. Izvedli smo primerjavo z obstoječo fitocenološko karto iz leta 1973, ki pa se je od zdajšnjih ugotovitev glede razporeditve združb močno razlikovala. Preučili smo vpliv abiotskih dejavnikov rastišča, ki pomembno vplivajo na pojavljanje gozdnih združb. S primerjavo rastiščnih dejavnikov na podlagi Ellenbergovih fitoindikacijskih vrednosti smo ugotovili, da so se najbolj spreminjale vrednosti za talno vlago, reakcijo tal in preskrbljenost s hranili. Naravna vrstna sestava se je ohranila le na najbolj odročnih in težko dostopnih mestih. Ugotovili smo, da so gozdovi v večjem delu območja spremenjeni zaradi preteklega gospodarjenja za potrebe fužinarstva in da gre v nekaterih sestojih za sukcesijo na potencialnem rastišču jelovo-bukovih gozdov. Vračanje naravne vegetacije poteka počasi predvsem zaradi odsotnosti semenskih virov in konkurenčnosti trenutno prevladujočih vrst. On northern slope of Vancovec, which lies above Železniki, 27 phytosociological relevés were conducted using standard Central-European phytosociological method. They belong to four different associations: Homogyno sylvestris-Fagetum Marinček et al. 1993, Galio rotundifolii-Abietetum M. Wraber 1959, Lamio orvalae-Fagetum (Ht. 1938) Borhidi 1963 and Lamio orvalae-Aceretum pseudoplatani P.Košir & Marinček 1999. The relevés were so similar that classifying them proved somewhat difficult. In the existing phytosociological map from the year 1973 different distributions were mapped compared to the new findings regarding the associations of the studied area. The influence of abiotic site factors, which play an important role in the distribution of associations, was studied. A comparison of Ellenberg-type indicator values established that moisture, reaction and nutients changed the most among the associations. Natural species composition remains only in the most remote and hard-to-reach places. It was found that most of the forests in the studied area are still affected by past managament practices, which were influenced by the nearby ironwork industry. The present associations in some of those forests represent a succession on potentialy mixed fir-beech sites. The return of natural vegetation is slow due to the absence of seed sources and the competitive strength of the currently present species. fitocenologija Vancovec vegetacija Železniki phytosociology Vancovec vegetation Železniki true false false [A.
