Abstract
Zaradi vse višjih cen dela se nega gozda v Sloveniji opušča. V sklopu diplomske naloge je bila narejena primerjava klasičnega izbiralnega in situacijskega načina redčenja v bukovem drogovnjaku na območju GGE Besnica. V tem sestoju smo postavili 10 raziskovalnih ploskev velikosti 400 m2, petim ploskvam smo določili izbiralni način, preostalim pa situacijski način. Pri odkazilu smo opravili časovno študijo, izmerili težavnost dela s pomočjo merilnika utripa in izmerili prsni premer izbrancev ter konkurentov. Pri sečnji smo poleg časovne študije in težavnosti dela merili tudi porabo energije za polnjenje baterijske verižne žage. Po končani sečnji smo pregledali še sproščenost izbrancev. Glede težavnosti smo pri odkazilu ugotovili višji povprečni pulz pri situacijskem načinu, pri sečnji pa je višji povprečni pulz pri izbiralnem načinu. Iz časovne analize smo ugotovili, da je poraba časa pri odkazilu in sečnji pri situacijskem načinu občutno manjša kot pri izbiralnem, poleg tega je manjša tudi poraba električne energije.

Title:Comparing the effects of traditional selective and situational thinning
Abstract:
Due to constantly increasing labor prices, forest tending in Slovenia is increasingly reduced. Within the framework of the diploma thesis, a comparison was made between classical selective and situational thinning in a beech stand in the Besnica forestry unit. For this purpose, 10 experimental plots of 400 m2 were established. In the tree marking phase, we conducted a time study, measured the difficulty of the work with a heart rate monitor, and measured the DBH of crop trees and their competitors. During felling, we conducted a time study and assessed the difficulty of the work, while also measuring energy consumption for charging the battery chainsaw. After felling, we checked the growth spaces of the released crop trees. Regarding the difficulty level, we found that the average heart rate was higher in the situational thinning method than in the selective thinning during the tree marking phase, while during harvesting the average heart rate was higher in the selective thinning. In the time analysis, we found that the time required for marking and felling trees was significantly lower in the situational thinning method, as was the energy consumption for electricity.
