Listed Plants by County

Oregon's threatened and endangered plants are legally protected on non-federal public lands throughout the state and projects proposed on these lands require consultation with ODA. This list shows all threatened and endangered plants known to naturally occur in each Oregon county. All listed plants documented in each county must be addressed during ODA consultation, pre-project botanical surveys, and impact assessments.

If a listed plant is discovered in a county where it has not been previously documented, it remains legally protected and must be reported to ODA. Plants that have been introduced to counties where they don't naturally occur are not included in this list. While introduced populations are protected and need to be considered during consultation and pre-project surveys, the plants are not expected to spread beyond their original planting sites, so including them in surveys throughout the rest of the county is unnecessary at this time.
