Occurrence locations and trait data for freshwater fishes, amphibians, and reptiles native to the state of Oregon

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-08-19T00:00:00Z
These datasets include occurrence points and trait data for freshwater fishes, amphibians, and reptiles native to Oregon State. Occurrence data were extracted from the VertNet database and include points within Oregon, Washington, and Idaho, as well as points found within ecoregions that overlap with Oregon state (U.S. EPA Level III EcoRegions). Occurrence points include records from years 1930-2002, and only records with associated museum voucher specimens were included. Database was updated to include one record per species, per year, at a given location. Records were evaluated by taxonomic experts for each species, and suspicious records were either verified or excluded. Trait data were gathered from published and openly available sources. Each column (trait value) for each taxon is described in detail in the datasets, including procedures for replacements of missing values.
