The Oregon Department of Agriculture Native Plant Conservation Program (ODA) is responsible for the periodic review of the Oregon State List of Endangered and Threatened Plants (OAR 603-073-0060 & 0070). In 2022 and early 2023, ODA worked with federal and state agencies in Oregon, Washington, California, Nevada, and Idaho, local Oregon governments, non-profit organizations, and citizens to collect population data, threat information, and gain an understanding of the species’ current condition from those most familiar with each species. For each species, ODA presented information on 1) habitat and ecology, 2) geographic range, distribution, and abundance, 3) factors affecting survival, and 4) current condition (i.e., representation, resiliency, and redundancy) to a Technical Advisory Committee in January and February 2023.

Following a public comment period, the species below have been added to OAR 603-073-0070:
