Reliefne značilnosti tal in objedanje mladja s strani velikih rastlinojedih parkljarjev v jelovo-bukovem gozdu = Topography and deer browsing in a mixed silver fir-beech forest
Roženbergar, Dušan ; Klevišar, Robert ; Diaci, Jurij
Veliki rastlinojedi parkljarji (VRP) različno vplivajo na razvoj gozdnih ekosistemov. Eden izmed najbolj negativnih vplivov, ki ga imajo na dolgoročni razvoj gozdov, je posledica kroničnega ...čezmernega objedanja mladja. Namen raziskave je bil s pomočjo analize objedanja v delu dinarskih jelovo-bukovih gozdov ugotoviti, kakšen vpliv na intenzivnost objedanja imajo habitatne značilnosti prostora in relief. Povprečna objedenost mladja je bila 70 %, analiza višinske strukture mladja pa je pokazala, da ni prehajanja gorskega javorja in jelke v zgornje višinske plasti. Potrdili smo vpliv stopnje kritja za VRP in reliefa na stopnjo objedenosti. Največ poškodb smo zabeležili na grebenih in v vrtačah. Glede na rezultate naših analiz v prihodnje v jelovobukovih gozdovih na območju naše raziskave ne bo mogoče zagotoviti primesi jelke in gorskega javorja v zgornjih sestojnih položajih. Če želimo v tem delu Slovenije vzgojiti pestre gozdove, bo poleg gozdno-gojitvenega ukrepanja nujno nadaljevanje intenzivnega gospodarjenja z VRP v smislu zmanjševanja njihovih gostot.
