Oregon Spotted Frog (Rana pretiosa) Observations in Oregon (ver. 4.0, February 2022)

February 10, 2022

This dataset contains information from surveys conducted 2016-2021 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort in Oregon. USGS research activities 2016-2021 were divided into seven study design categories: breeding (egg mass counts), mid-level (visual encounter surveys for occupancy monitoring), apex (mark-recapture), telemetry, trapping, water quality (skin microbiome swabbing), and genetics (egg mass embryo or toe-clip tissue samples). Data consist of Oregon spotted frog observations aggregated by date, location, life stage, sex, and project. These data were compiled from multiple studies employing different survey methods, thus we caution users that counts are not directly comparable among projects; any counts may represent multiple detections of the same individual.
