Oregon spotted frog (Rana pretiosa) observations in Oregon, 2016-2019: U.S. Geological Survey data release

Abstract/Summary

This dataset contains information from surveys conducted 2016-2018 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort in Oregon. USGS research activities in 2016, 2017, and 2018 were divided into six study design categories: breeding (egg mass counts), mid-level (visual encounter surveys for occupancy monitoring), apex (mark-recapture), telemetry, trapping, and water quality (skin microbiome swabbing). 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.
