This article discusses the spatial and temporal aspects of hydrological processes in catchments after logging for different landscape conditions Central Siberia. For this discussion, results our own research Sayan Mountains, Yenisei Ridge, Angara River basin, Khamar-Daban ridge literature data were involved. It analyzed impact felling area to change river flow development erosion at catchment a...

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...

There is an intense debate about the effects of postfire salvage logging versus nonintervention policies on regeneration of forest communities, but scant information from experimental studies is available. We manipulated a burned forest area on a Mediterranean mountain to experimentally analyze the effect of salvage logging on bird-species abundance, diversity, and assemblage composition. We us...

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...
