Book Description
Excerpt from Sampling Methods for Terrestrial Amphibians and Reptiles Concern about the value of old-growth Douglas-fir forests to wildlife in the Pacific Northwest began escalating in the late 19705. The available information on wildlife habitat relationships suggested that as many as 75 species including amphibians, birds, and mammals, could be dependent on old-growth forests. The usda Forest Service chartered the old-growth Forest Wildlife Habitat Program to investigate the role old growth plays in maintaining viable populations of wildlife. It was apparent that broad surveys of vertebrate communities would be necessary to determine which species were truly closely associated with old-growth forests. Insufficient guidance on techniques, procedures, and sample sizes was available in the existing literature. We assembled a team of researchers from universities and Federal agencies to conduct pilot studies to develop sampling protocols and to test the basic experimental design for contrasting the wildlife values of young, mature, and old-growth forests. The sampling protocols resulting from the pilot studies were implemented in 1984-86 across broad areas of the Cascade Range in southwestern Washington and in Oregon, the Oregon Coast Ranges, and the Klamath Mountains of southwestern Oregon and northern California. Naturally, improvements were made to the protocols as time passed. A tremendous amount of experience in sampling was gained.
