We used visual surveys and environmental DNA (eDNA) sampling to document the presence of all life stages of foothill yellow-legged frogs (Rana boylii) at historically occupied sites. We visited 52 stream reaches (sites) on federal and private lands between June and September of 2019. This dataset includes counts of amphibians, crayfish, and fish observed during each site survey, as well as habitat and water sampling covariates.
