Vpliv objedanja na naravno pomlajevanje po vetrolomu v Trnovskem gozdu : diplomsko delo - visokošolski strokovni študij - 1. stopnja

Pogostost pojavljanja naravnih ujm je zaradi podnebnih sprememb vse večja. Posledično so večje in pogostejše tudi poškodbe gozdov. Dodaten problem po ujmah predstavlja rastlinojeda parkljasta divjad, ki je neenakomerno porazdeljena v naravi. Prehranske zmožnosti okolja temu niso prilagojene, kar otežuje naravno pomlajevanje gozdov. Proučevali smo vpliv objedanja rastlinojede parkljaste divjadi na naravno pomlajevanje po vetrolomu v Trnovskem gozdu. Z raziskavo smo poskušali ugotoviti učinkovitost ograj pri zaščiti mladja po vetrolomu. Terenski popis mladja je potekal v gozdno gospodarski enoti Predmeja in sicer na dveh raziskovalnih objektih, kjer smo popisali 80 ploskev. Štirideset od teh se je nahajalo v ograjenih površinah, štirideset pa izven ograjenih površin. Gostota v ograjenih površinah je bila 39875 osebkov na hektar, medtem ko je bila gostota izven ograjenih površin 19875 osebkov na hektar, kar nakazuje velik vpliv rastlinojede parkljaste divjadi na proces pomlajevanja.

• Title: Influence of ungulate browsing on natural regeneration after windthrow in Trnovski gozd

Abstract

The frequency of natural disturbances is increasing due to climate change. Therefore, damages in forests occur more regularly and with greater magnitude. In addition, after disturbances the spatial distribution of ungulates is irregular which leads to unevenly distributed food sources and therefore inhibition of the natural regeneration of forests. This study focuses on the influence of ungulates browsing on natural regeneration after windthrow in Trnovski gozd. The efficiency of fencing natural regeneration was analysed. Field inventory was performed in a forest management unit Predmeja on two sites where we established 40 plots outside and 40 plots inside the fence. The results show that there was no herbivore grazing and that the densities of natural regeneration were higher in fenced areas.
