Abstract
Meritve za magistrsko nalogo so potekale poleti in jeseni l. 2009 na OE Novo mesto, v GGE Poljane, oddelek 43. Namen naloge je bil primerjati prilagojeno strojno sečnjo (strojna sečnja s kombinacijo sekača z motorno žago) in klasično sečnjo (motorna žaga in traktor) v pomlajenih sestojih smreke s primesjo bukve, gorskega javorja in jelke. Pred sečnjo smo postavili mrežo vzorčnih ploskev za odrasli sestoj in pomladek ter popisali vse osebke na ploskvah, po sečnji pa smo analizirali še poškodovanost preostalih dreves in pomladka ter posneli svetlobne razmere. Ugotovitve kažejo, da med tehnologijama ni velikih razlik. S prilagojeno strojno sečnjo je bilo na novo poškodovanih 14 % dreves, pri klasični sečnji 16 %, skupaj s starimi poškodbami 42 % in 45 %. Pri prilagojeni strojni sečnji je bilo največ poškodb na deblu, pri klasični na korenovcu, pri obeh pa so prevladovale največje poškodbe. Delež na novo poškodovanih dreves in pomladka je bil v značilni povezavi s položajem ploskve glede na prometnice in jakostjo poseka na ploskvi. Poškodovanost pomladka po prilagojeni strojni sečnji je v povprečju znašala 34 %, po klasični sečnji 38 %, poškodovanost po divjadi pa dodatnih 4,6 %. Največ poškodb je bilo na osebkih do višine 50 cm in ob prometnicah.

Title:Suitability of two timber harvesting technologies in stands in regeneration on silver fir-beech sites in the area of high Karst
Abstract:
Measurements for the thesis took place in the summer and fall of 2009 in the Novo mesto forest management region, Poljane forest management unit, conpartment 43. The purpose of the thesis is to compare the effects of combined machine logging (machine logging combined with a worker using a chainsaw) with motor-manual cutting (the use of a chainsaw and a tractor) in a spruce stand in regeneration with admixture of beech, sycamore maple and fir. Before cutting the trees, we constructed a network of sample plot for analysing mature trees and regeneration and recorded all the specimens on the plot. Following the logging, we analysed the damage to the remaining trees and regeneration and we recorded the light conditions. Findings have shown that both methods yield no significant difference. Combined machine logging brought about 14% of trees to be newly damaged, whereas with motor-manual cutting the damage was done to 16% of trees. All together with old injuries, it accounts for 42% and 45% of trees to be damaged, respectively. In combined machine cutting predominant damage was done to the trunk and in motor-manual cutting damage prevailed on lower part of the bole and roots. With both methods severe damages predominated. The extent of the newly damaged trees and regeneration was greatly dependent on both the position of the plots with regard to the proximity to the skid trail and the intensity of the logging. The damage done to regeneration in combined machine logging in average amounted to 34%, compared to 38% caused by motor-manual cutting. An additional 4.6% of damage to young forest was caused by wild game. Most damage was observed on specimen of up to 50 cm in height and situated close to the skid trails.
