Roads and motorized trails can fragment landscapes and reduce the quality of adjacent habitat for a wide range of wildlife species. This report demonstrates an approach for assessing the influences of the extent and configuration of motorized route networks on habitat quality for fishers (Martes pennanti) in Sierra National Forest, in the central Sierra Nevada range of California.
This report summarizes existing research on habitat fragmentation and provides recommendations to the BLM on how it can incorporate habitat fragmentation analysis into its travel management planning process.
The President’s Council on Environmental Quality developed this report about off-road vehicle use on public lands in 1979. This well-written and insightful report offers a historical perspective about how the modern off-road vehicle came to be and analyzes the issues surrounding ORV use on public lands, the policies taken by the land agencies to address the issues, and offers solutions.
