The Washington Natural Heritage Program maintains a comprehensive database of sitc- 

 spxxrific information on reported occurrences of Sensitive, Threatened, Endangered and known 

 historic occurrences of Possibly Extinct or Extirpated plant species in Washington. At the time 

 of writing most wetlands in Washington have not been surveyed for the occurrence of State 

 Sensitive, Threatened, Endangered and Possibly Extinct or Extirpated plant ics. 



NOTE: Unidentified plant species collected during site visits should be identified only by 

 qualified botanists familiar with the Pacific Northwest flora. If the study site is an historic 

 collection site for a Possibly Extinct or Extirpated plant species or is within 1/2 mile of such a 

 site, then a rare plant survey by a qualified botanist familiar with the Pacific Northwest flora 

 should be conducted to determine the presence of the species of concern. 



JUSTIFICATION 



Sonr>e species of Threatened or Endangered plants are found exclusively or predominantly in 

 wetland habitats. Examples include Wenatchee larkspur Delphinium viridescens in the 

 Leavenworth/Wenatchee area, and howellia HowelUa aquatiUs in Oark and Spokane 

 Counties.Table 2 lists State-listed Threatened and Endangered species that may be found in 

 wetlands. 



Some species of Possibly Extinct or Extirpated plant sp>edes are (were) found exclusively or 

 predominantly in wetland habitats. Examples include swamp sandwort Arenaria paludicola 

 west of the Cascades, and purple spike-rush Eleocharis atropurpurea in Chelan County. Table 3 

 lists State-listed sp>ecies thought to be Possibly Extinct or Extirpated from Washington and
