CLARK COUNTY RARE SPECIES LIST (18 March 2004) |
|
As of the date above, this list provides information for the 194 Clark County plants and animals included on the Nevada
At-risk Animal and At-risk Plant and Lichen
tracking lists and on the Nevada Plant and Animal Watch List. 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. Information provided for each taxon in the columns below include the various agency status and rank designations, sand and wetland habitat indicators, and endemic status within Nevada. A new Occurrence Status (OCC) column has been added to the left side of the list to show any special status within the county: 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 most 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. Click on a column heading for an explanation of that column. You may need to scroll horizontally in your browser to see all columns. You may also jump to the at-risk taxa or the watch-list taxa. |
