This project plans to provide information on how natural and anthropogenic factors affect the distribution and abundance of Rocky Mountain Tailed Frogs. The goal of this study was to evaluate the influence of abiotic and biotic factors on Rocky Mountain tailed frog (Ascaphus montanus) tadpole densities across a nested hierarchy of spatial scales in two biogeoclimatically distinct stream networks. Although tadpoles were widely distributed and observed in great abundance throughout both networks, the factors influencing tadpole abundance differed across spatial-scales, between networks, and between tadpole age classes. Detailed results can be found in the associated reference reports.
