Lyon County Rare Species List (2004) - Nevada Natural Heritage Program

As of the date above, this list provides information for the 80 Lyon 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: ?=possible or predicted in the county but not yet confirmed, e=endemic in-state (known in Nevada only from this county), E=endemic (known worldwide only from this county), and I=only introduced or re-introduced occurrence(s) present in this 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.
