Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: August 01, 2026 at 04:37 AM | Dataset Last Updated: August 19, 2020 at 12:00 AM
We used visual surveys to document the presence of all life stages of Cascades frog (Rana cascadae) at historically occupied sites. We surveyed 67 sites 1-2 times between May and August of 2018 and 2019. This effort was a continuation of 2001-2004 surveys conducted at the same site pool. This dataset includes counts of amphibians, reptiles, and fish observed during each site survey, as well as habitat covariates.
