Presoja primernosti rabe sodobne sortimentne metode v revirju Ivančna Gorica : diplomsko delo - visokošolski strokovni študij

Črnič, Roman (avtor), Krč, Janez (mentor)

V diplomski nalogi smo s slučajnostnim sistematičnim vzorčenjem anketirali 54 lastnikov gozdov revirja Ivančna Gorica. Z analizo smo ugotovili, da je realizacija sečnje in spravila lesa odvisna od socialno-ekonomskega tipa posesti. Tako so največ posekali v gozdovih v lasti dopolnilnih kmetij (182 % dovoljenega poseka), najmanj pa na čistih kmetijah (121 % dovoljenega poseka). 31,5 % lastnikov ima opravljene tečaje varnega dela, večina ima narejen tečaj varno delo z motorno žago. 57,4 % lastnikov pozna strojno sečnjo, vendar bi jo v svojem gozdu uporabilo le 29 % lastnikov. Z večanjem gozdne posesti se veča tudi pripravljenost za uporabo strojne sečnje v svojem gozdu. V drugem delu naloge smo izločili gozdove v fazi drogovnjaka ali starejših razvojnih faz, glede na naslednje vplivne dejavnike: mešanost iglavcev večja od 70 %, naklon terena največ 30 % ter skalovitost največ 50 %. Po upoštevanju stabilnostnih dejavnikov, ekonomskega dejavnika in minimalne površine delovišča 8 ha, je ostalo 246,8 ha oziroma 9,5 % gozdov primernih za strojno sečnjo. To pomeni, da bi pri 29 % pripravljenosti lastnikov za uporabo strojne sečnje lahko strojno sekali v revirju Ivančna Gorica le na 73,1 ha oziroma 2,5 % površin v revirju Ivančna Gorica. Rešitev za izvajanje strojne sečnje v večjem obsegu vidimo v združevanju lastnikov gozdov in s tem možnemu povečanju koncentracij strojnih sečenj in posledično zmanjševanju stroškov premika strojev.

Izvleček

For the purpose of the graduation thesis, 54 forest owners were interviewed based on a random systematic sampling in the Ivančna Gorica forest district. The analysis shows that the realization of felling and skidding of wood depends on the socio-economic type of land tenure. Therefore the maximum cut was performed in forests owned by complementary farms (182% of the allowable cut), but the least on fully operational farms (121% of the allowable cut). 31.5% of the owners completed courses in safety at work; most of them completed a course of safe work with a chainsaw. 57.4% of the owners are familiar with the motorized felling but only 29% of the owners would implement it in their forests. By increasing forest estates the willingness to use motorized felling increases in privately owned forests as well. In the second part of the thesis the forests in the phase of a pole stand or older life stages were excluded, due to the following influencing factors: share of coniferous trees in growing stock is greater than 70%, the steepness of the terrain not more than 30% and not more than 50% of rocky terrain. According to the stability factors, economic factors and minimum management site surface of 8 ha, 246.8 ha or 9.5% of the forests are suitable for motorized felling. This means that in 29% of the willingness of the owners to use motorized cutting in the forest district of Ivančna Gorica, only 73.1 ha or 2.5% of the forest estates could be cut in the motorized way. The solution for the implementation of the motorized felling on a larger scale can be sought in the integration of forest owners and therefore in the likely increase of the concentrations of motorized felling. Furthermore, consequently the costs of moving machinery can be reduced.
