Type N Experimental Buffer Treatment Study: The Amphibian Demographic Response

The Washington State Department of Fish and Wildlife is implementing the amphibian demographic response portion of the Type N Experimental Buffer Treatment Study. Forest and Fish Report (FFR) research focuses on amphibians because they were a factor in establishing riparian buffer prescriptions in headwater basins and are covered in the Habitat Conservation Plan (HCP). Amphibians represent the vertebrate group that is thought to be most vulnerable to environmental change, and thus, most suitably monitor environmental conditions (Wake 1991).
