Nevada Natural Heritage Program
CLARK COUNTY RARE SPECIES LIST
As of the date above, this list provides information for the 173 Clark County plants and animals included on the Nevada Sensitive Animal and Sensitive Plant and Lichen lists and on the Nevada Plant and Animal Watch List, including the various agency status and ranks, geographic range by state(s) and Nevada counties, and sand and wetland habitat indicators. These data reflect only what was entered in our computer databases as of the above date; additional information for some species may await processing in paper files, or may have been entered subsequently. More detailed state-wide information for these taxa is available in our Detailed Rare Plant and Lichen and Detailed Rare Animal lists, and in the Nevada Rare Plant Atlas, which provides comprehensive information on habitat, life-history, description, threats, survey status, literature sources, and known locations, for many plant taxa. Further information may be available on-line for some taxa in other lists or reports, or as maps or images, and general information is available for nearly all taxa on the NatureServe Explorer web site.
