ABSTRACT- The Pacific Northwest region of the USGS Amphibian Research and Monitoring Initiative includes 5 states with markedly diverse ecosystems and large amounts of public land. The core of our program is monitoring of defined areas using probabilistic sampling designs to produce an estimate of the proportion of sites occupied by amphibians. We are establishing three such monitoring areas in partnership with the National Park Service and the Bureau of Land Management (BLM): the North Coast and Cascades Network of National Parks, Canyonlands National Park and surrounding BLM lands, and a large monitoring area encompassing BLM lands in the Northern Great Basin Desert. Combined, these monitoring areas cover over 6.7 million ha of federal lands and will provide information on at least 8 species of amphibian and numerous covariates in 3 western states. We are also monitoring 6 amphibian populations using more intensive methods and are conducting a broad scale study to determine current occupancy of historic amphibian sites in western Oregon and the Great Basin Desert. Our research includes non-native species, timber harvest, fire effects, off-road vehicle use, cattle grazing, and ultraviolet-b radiation.
