Motor-manual timber felling is one of the most dangerous operations in forest and cannot be completely replaced by fully mechanized harvesting a harvester when dealing with large deciduous trees. Shifting center gravity tree ready to felled beyond its tipping line using conventional wedges because worker directly behind stem under crown until just before falls. The can hit trunk itself, but als...

The hypothesis that habitat restoration will provide for community reestablishment and the creation of habitat heterogeneity was examined with regards to the herpetofauna of longleaf pine sandhills in northwest Florida. The herpetofaunal response to restoration was examined in fire-suppressed, hardwood-dominated areas treated with (1) spring fire; (2) felling or girdling; or (3) a granular form...

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...

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...
