Amphibian survey in streams within North Cascades National Park tabular data, 1996-2004. To obtain baseline data on the abundance and distribution of stream obligate amphibian species in the North Cascades National Park Service Complex, particularly Ascaphus truei and Dicamptodon tenebrosus. To evaluate the environmental factors affecting the distribution of stream amphibians. These objectives will assist in the development of long-term monitoring protocols for stream amphibians

We sampled 168 stream segments from nine watersheds in North Cascades National Park Service Complex during two inventory efforts conducted from 1996-1998 and 2003-2004. Surveys entailed stream habitat characterizations such as stream channel and flow measurements, vegetation and canopy cover measurements, and stream substrate classification. as well as sampling for stream amphibians. When found, amphibians were photographed, classed into age/lifestage categories and a variety of body size measurements were taken. No voucher specimens were collected.
