Results of an amphibian inventory in the North Cascades National Park Service Complex (part of a four-year program to inventory amphibians in Pacific Northwest National Parks). From the author's abstract: "The objectives of this study were to conduct a baseline inventory, evaluate environmental factors affecting distribution of amphibians, and develop protocols for both extensive and intensive monitoring...This report includes information collected in 1998 focusing on finishing Bridge Creek and Thunder Creek watersheds and data collected in conjunction with the Seattle City Light funded lake ecology project. Physical, chemical and amphibian abundance and distribution data were collected at nineteen stream reaches, and seventy-two lake/ponds. The tailed frog, Ascaphus truei, and Cascades frog Rana cascadae were the only amphibians captured in stream habitats. Nine species of amphibians were found in the lake/ponds surveyed. They included: Ambystoma gracile, Ambystoma macrodactylum, Ascaphus truei, Bufo boreas, Hyla regilla, Rana aurora, Rana cascadae, Rana luteiventris, and Taricha granulosa. Six stream reaches in Thunder Creek and Fisher Creek watersheds were intensivley sampled for tailed frog tadpoles in an effort to determine the number of age class cohorts present. It appears that three or possibly four age classes are represented in these streams. Small sample sizes (25-56) are not adequate to make a reliable assessment of age classes. Ascaphus tadpole length frequency data are presented." Also gives results of tissue DNA sampling from frogs collected in 1997 to determine their species.
