Oregon's Rare & Endangered Plants
Siskiyou mariposa lily, known from just one
occurance in Oregon, and not seen here for
several years. (Norm Jensen)The Oregon Natural Heritage Program lists 29 plant species as endangered and 28 other species as threatened. Ten of the endangered species and seven of the threatened ones are also on the list established by the Fish & Wildlife Service of the Federal government. In order to encourage increased interest in our rare and endangered plant species, the Rare and Endangered Plants Committee of NPSO will present descriptions and photos of these species on this website. We plan to describe four to six species each year.
Additional information about our rare plant species is available on the following websites:
- Interagency Sensitive Species Program
- Oregon Department of Agriculture
- Oregon Natural Heritage Information Center - Plant Data
- US Fish & Wildlife Service
