Direct and indirect ecological impacts of roads and their expansion are well documented: habitat degradation, ecosystem fragmentation, changes in natural drainage systems and water quality. Important landscape scale impacts concern roads about direct and indirect effects on deforestation and land use land cover change, that lead to habitat loss and fragmentation, edge effect, resources exploita...

The cumulative effect of many local forest land use turnover reflects the character of the local site; disturbances can be estimated from an analysis of forest there is no evidence of region-wide gradients of regeneration distribution at the scale of the entire landscape. To gauge or clearance. the regional impact of forest clearance and regeneration, a Modern forest is concentrated along steep...

Although wildlife biologists need reliable estimates of white-tailed deer (Odocoileus virginianus) density to facilitate management, few studies have examined distance sampling as a density estimation technique for this species. We compared direct (i.e., spotlighting from road transects) and indirect (i.e., counting pellets on randomly placed transects) distance-sampling techniques for estimati...

Water quality in mountain streams of the southern Appalachians varies seasonally and with storms. In an effort to validate Total Maximum Daily Loads (TMDLs) for sediment in the Chattooga River Watershed (NE Georgia, NW South Carolina, and SW North Carolina), we studied four tributary streams over an eighteen-month period. Two of the streams had completely forested watersheds; one stream was a b...
