State Status State Status of plant species is determined by the Washington Natural Heritage Program. Factors considered include abundance, occurrence patterns, vulnerability, threats, existing protection, and taxonimic distinctness.
E = Endangered. In danger of becoming extinct or extripated from Washington. T = Threatened. Likely to become endangered within the near future in WA if the factors contributin to pop decline or habitat loss continue. S = Sensitive. Vulnerable or declining and could become endangered or threatened in the state without active management or removal of threats X = Possibly extinct or Extirpated. Documented to have previously occurred within WA, but no longer thought to be present here. P1 = Priority 1. Rare nonvascular plant but with insufficient information to assign another rank. P2 = Priority 2. Nonvascular plant of concern but with insufficient information to assign another rank. R1 = Review group 1. Of potential concern but needs more field work to assign another rank. R2 = Review group 2. Of potential concern but with unresolved taxonomic questions. W = Watch. Species that are more abundant and/or less threatened in WA than previously thought, no longer a focus of conservation efforts.
Federal Status Federal Status under the U.S. Endangered Species Act (USESA) as published in the Federal Register. For complete definitions see http://www.fws.gov/endangered/laws-policies/section-3.html
LE = Listed Endangered. The plant is in danger of extinction throughout all or a significant portion of its range. LT = Listed Threatened. The plant is likely to become endangered within the foreseeable future throughout all or a significant portion of its range. PE = Proposed Endangered. A plant that is proposed to be listed as endangered and is undergoing a review process. PT = Proposed Threatened. A plant that is proposed to be listed as threatened and is undergoing a review process. C = Candidate species. A plant for which FWS or NOAA Fisheries has on file sufficient information on biological vulnerability and threats to support a proposal to list as endangered or threatened. SC = Species of Concern. An informal term referring to a species that might be in need of conservation action. Such species receive no legal protection and use of the term does not necessarily imply that a species will eventually be proposed for listing. NL = Not listed. Used when two portions of a taxon have different federal status.
