Distribution, relative abundance, and activity of bat species in Crater Lake National Park, Oregon Caves National Monument, and Redwoods National and State Parks
Duff AA. 2005. Distribution, relative abundance, and activity of bat species in Crater Lake National Park, Oregon Caves National Monument, and Redwoods National and State Parks. Ashland, Oregon
"Scant information exists regarding the status, diversity, and distribution of bats throughout much of northern California and southern Oregon. As a result, biologists and land managers are unable to predict or evaluate the impacts that management activities such as habitat alteration, fire, and grazing practices have on the community of bats. Because bats are nocturnal and proficient at flight they are particularly difficult to inventory. The objectives of this field study were to: 1) determine the diversity, relative abundance, and activity of bats in Crater Lake National Park (CRLA) and Redwood National and State Parks (REDW), 2) determine the distribution of bats in CRLA and REDW, 3) compare acoustical and live capture techniques for inventorying bats, and 4) determine the effect of bat friendly gates on bat activity at cave entrances in Oregon Caves National Monument (ORCA)" (from Executive Summary)
