A method for examining the impacts of disturbance on stream water quality based on paired catchment “control” and “response” water quality time series is described in relation to diagrams of cumulative flux and cumulative flux difference. The paper describes the equations used and illustrates the patterns expected for idealised flux changes followed by an application to stream water quality dat...

The objective of this review is to compare the cost of coppice and longer rotation poplar harvesting technology. Harvesting technology for short rotation poplar has evolved over the years to address both coppice harvest and single-stem harvest systems. Two potential approaches for coppice harvesting are modified forage harvesters and modified mulcher-balers. Both of these systems effectively ha...

A new measurement concept for cut-to-length forest harvesters is presented in this paper. The cut-to-length method means that the trees are felled, delimbed and cut-to-length by the single-grip harvester before logs are transported to the roadside. The concept includes measurements done to standing trees before felling to calculate optimal length of logs. The modern forest harvesters use mechan...

The effect of initial first-order lateral root (FOLR) groupings of northern red oak (Quercus rubra) seedlings on a high quality mesic site was followed for eleven years on a shelterwood and a clearcut area. The initial FOLR number groups were empirically determined as low (0 to 6) medium (7 to 12) and high ( 12). The shelterwood overstory was removed before the beginning of the eighth growing s...

Villagers, particularly the women, have once again come forward to launch another novel movement to save Uttarakhand forests and the environment. Established in July 1995, the Rakshasutra (Safety thread) movement struggled to stop the operations of Uttar Pradesh Forest Corporation (UPFC). Through the help of the Himalayan Environmental Education Society volunteers, women consolidated and unit...

Estimates of dead and down woody material (DWM) biomass are important for nutrient cycling, wildlife habitat assessment, fire effects climate change science. 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...

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...
