Discussion

Of conservation concern.

Eriogonum chrysops is known from five scattered sites in the Skull Creek area of Malheur County. It is no longer considered a candidate for threatened status under the provisions of the Endangered Species Act. However, it still is considered a “threatened” species by the state of Oregon.
