Most methods used to sample initially assess volume then estimates wood density convert biomass. To initial decomposition rate, this study examined in situ lodgepole pine logs at the Tenderfoot Creek Experimental Forest (TCEF), central Mon...

The study took place in plantation forest, inhabited by the New Zealand long-tailed bat (Chalinolobus tuberculatus), in which trees are harvested between the ages 26-32 years. We determined home ranges by radiotracking different bats in areas that had and had not been recently clear-fell harvested. Home ranges we...

This paper seeks to answer the question of whether magnitude vibrations affecting whole body harvester operator (WBV) that are generated by boom is affected size processed trunk volume, specify closer, WBVs during forest logging, and localise these in individual partial operations. For purposes, production process, i.e., was divided into six operations (Searching; Felling; Processing; Unproduct...
