Gojitvena obravnava in razvoj sestojev robinije v spodnji Vipavski dolini

Marka, Patrich (author), Roženbergar, Dušan (mentor)

Robinija je v spodnji Vipavski dolini vse bolj razširjena drevesna vrsta, katera počasi že izpodrinja oz. je nekje že izpodrinila avtohtono vegetacijo. Opravili smo analizo razvoja robinijevih sestojev po opravljeni panjevski sečnji z namenom ugotovitve dinamike njihovega razvoja. Želeli smo izvedeti ali so v teh sestojih prisotne tudi avtohtone drevesne vrste in ali so mogoči gozdnogojitveni ukrepi, s katerimi bi omogočili večjo pestrost drevesne sestave. Ugotovili smo, da je robinija v zgornji sestojni plasti dominantna drevesna vrsta, ki nima konkurence. Pod zastorom dominantnih dreves in v podmladku se je pojavljalo nekaj drevesnih vrst, ki bi jim lahko z ustreznim gozdnogojitvenim ukrepanjem pomagali preiti v zgornjo sestojnio plast, s čimer bi povečali pestrost drevesne sestave. Predlagali smo nekatere gozdnogojitvene ukrepe, ki bi to po predvidevanjih omogočili. Problem pa je na tem območju lastništvo gozdov katero je po večini v zasebni lasti, lastnikom pa trenutne gozdnogojitvene smernice ustrezajo oz. v polni meri zadovoljujejo njihove potrebe in nimajo želje po spremembah.

• Title: Silvicultural treatment and development of black locust stands in the lower Vipava valley

Abstract

Black locust is an increasingly widespread tree species growing up in the lower Vipava valley, which has at some locations already displaced autochthonous vegetation. An analysis of the development of black locust stands after the clear cutting was carried out in order to determine the dynamics of the development of such stands and see what kind of silvicultural approaches could be used to enable greater diversity of tree composition. It was found that the black locust is the dominant tree species in the upper layer and has no competition. Under the canopy layer and in the regeneration, there are several tree species that could be promoted using appropriate silvicultural measures, thereby increasing the biodiversity of the stands. Some silvicultural systems have been proposed to do that, however the ownership of forests is a problem. Forests are mostly privately owned and forest owners are not willing to change their current silvicultural practices.
