Plant Conservation

The Oregon Department of Agriculture (ODA) can amend Oregon's threatened and endangered plant list in response to documented scientific evidence of increasing or decreasing threats to native plants, as presented by concerned Oregon residents. Once a petition has been received by ODA, the agency evaluates it using the criteria described in the Oregon Administrative Rules (OAR 603-073). 

Listing criteria

In order to be considered for listing as threatened or endangered in Oregon, a plant must meet all of the following criteria:

  • Name and description validly published or accepted for publication
  • Native to Oregon
  • Likely to become endangered, within the foreseeable future, throughout all or any significant portion of its geographic range
  • Natural reproductive potential in danger of imminent or continual failure

In addition, a listed plant must also face at least one of the following threats:

  • Most of the species' populations are undergoing imminent or active deterioration of range or habitat
  • An over-utilization of the species or its habitat is likely to occur
  • Existing state or federal programs and regulations are inadequate to protect the species or its habitat

Petitioning process
