20.500.12556/RUL-111648 Analiza vpliva divjadi na pomlajevanje v borovih nasadih pri Divači: primerjava med ograjenimi in neograjenimi površinami Analysis of impact of large herbivores on natural forest regeneration in pine plantations near Divača: a comparison between enclosed and open areas Na šestih posekanih in deloma ograjenih raziskovalnih ploskvah v bližini Divače smo s popisovanjem vrstne sestave grmovnic in mladja drevesnih vrst, njihove gostote in višinske strukture na ograjenih in neograjenih površinah ugotavljali vpliv divjadi na naravno pomlajevanje v borovih nasadih. Na lokaciji 1 se je poleg črnega gabra (Ostrya carpinifolia Scop.) in črnega bora (Pinus nigra J. F. Arnold) znotraj ograd uspešno pomlajeval še mali jesen (Fraxinus ornus L.), zunaj ograd pa še puhasti hrast (Quercus pubescens Willd.) in gorski javor (Acer pseudoplatanus L.). Na lokaciji 2 sta bila znotraj in zunaj ograd najpogostejša rešeljika (Prunus mahaleb L.) in puhasti hrast, znotraj ograd še črni bor, zunaj pa mali jesen in črni gaber. S parnimi primerjavami med ograjenimi in neograjenimi površinami smo ugotovili manjše statistično potrjene razlike med vrstno sestavo in višinsko strukturo pomladka in grmovnih vrst ograjenih in neograjenih površin, izrazil se je tudi vpliv rastišča na potek pomlajevanja. By examining the species composition, density and height structure of tree and shrub species on six deforested and partially fenced experimental plots near Divača the data was gathered for studying the impact of large herbivores on natural regeneration in pine plantations. The most successful species regenerating inside the fenced areas on location 1 were the European hop hornbeam (Ostrya carpinifolia Scop.), black pine (Pinus nigra J. F. Arnold) and South European flowering ash (Fraxinus ornus L.), followed by the downy oak (Quercus pubescens Willd.) and sycamore (Acer pseudoplatanus L.) in the unfenced areas. The most common species in both fenced and unfenced areas of location 2 were mahaleb cherry (Prunus mahaleb L.) and downy oak, inside the fenced area also the black pine while outside the fenced area South European flowering ash and European hop hornbeam. Through pairwise comparisons of fenced and unfenced areas minor statistically proven differences were found between the species composition and height structure of tree and shrub species of fenced and unfenced areas, however, a natural site with its productivity also significantly influences the regeneration process. naravno pomlajevanje divjad borovi nasadi Kras natural regeneration large herbivores pine plantations Karst true false false [M.
