One of the Oregon Biodiversity Information Center's main tasks is to list and rank rare, threatened, and endangered species in Oregon. Using our Biotics biodiversity database of species occurrences throughout the state and by consulting with agencies, specialists, academics, and the public, ORBIC reviews and publishes this list every two to three years.

Species ranks are important for natural resource management, prioritization of restoration or conservation efforts, and to highlight species that need more research or protection. The ranks that ORBIC produces are shared internationally through the NatureServe network of natural heritage programs and conservation data centers.

Definitions of ranks, lists, and abbreviations used in the RTE publications can be found on the RTE Definitions page.

Versions of our Rare, Threatened, and Endangered Species publication that are available as PDF format are listed below with links to those documents. Paper copies of older editions of the book may be available. Details on obtaining printed copies from Odin Ink at PSU are at the bottom of the page.

Notes on Species Lists in PDF and Spreadsheet Formats

These spreadsheets contain the same information in the RTE publication, but in an easily sortable format. Files are Microsoft Office and Open Office compatible.

A note on federal status: Before 2019, in the book and the PDF lists, federal status was reported on the state level. In the Excel lists, federal status was reported on the national level. For example, Columbia spotted frog is a federal Candidate in Oregon (C), but other populations in the US do not have this status, so its national federal status is partial status (PS). After 2019, both the PDFs and Excel excerpts only report the federal status as it applies to populations in Oregon.
