Adams, M.J., Pearl, C.A., McCreary, B., Galvan, S.K., and Rowe, J.C., 2017, Oregon Spotted Frog (Rana pretiosa) Monitoring in the Oregon Cascades 2012-2016: U.S. Geological Survey data release,


This dataset contains information from visual encounter surveys conducted between 2012 and 2016 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort in the Oregon Cascade Mountain Range. We surveyed 91 sites using a rotating frame design in the Klamath and Deschutes Basins, Oregon, which encompass most of the species' core extant range. Data consist of spotted frog counts aggregated by date, location, and life stage, as well as data on environmental conditions at the time of each survey.

USGS FRESC (Forest and Rangeland Ecosystem Science Center, Corvallis, Oregon) conducted research activities as part of an ongoing effort to study the population status and recovery of the Oregon spotted frog (Rana pretiosa) in the Oregon Cascades. Data were collected between 2012 and 2016 to assess trends in site occupancy and the influence of environmental factors on demographic parameters. The results of this study will contribute to our understanding of the biology of this sensitive species and can have implications for improved management efforts.
