Nevada Natural Heritage Program
NEVADA SENSITIVE PLANT AND LICHEN LIST
As of the date above, this list directs the plant data acquisition priorities of the Nevada Natural Heritage Program (NNHP), and provides current status information for 221 plant and lichen taxa. Taxa considered sensitive and actively inventoried by NNHP typically include those with federal or other Nevada agency status, and those with Global ranks (Grank 1-3) or declining trends indicating some level of range-wide imperilment. In general, a sensitive species is any taxon whose long-term viability has been identified as a concern. A separate watch list includes taxa that could qualify for the sensitive list in the future, or that recently have been removed from the sensitive list. NNHP passively accumulates data for watch list taxa.
Older editions of this list remain available on-line. A parallel Detailed Rare Plant and Lichen List provides additional information on Nevada Native Plant Society ranks; family names, observation history, habitat, range, trends, and land management for all sensitive and watch-list plants. Further information may be available on-line for some taxa in other lists or reports, or as maps or images. The Nevada Rare Plant Atlas provides more comprehensive information, including habitat, life-history, description, threats, survey status, literature sources, and known locations, for many plant taxa. General information is available for nearly all taxa on the NatureServe Explorer web site.
With few exceptions, we attempt to maintain current data on all identified sensitive taxa in Nevada. We currently have no information on which algae or non-lichenized fungi may be sensitive in the state, and are just beginning to develop information for mosses and lichens. Comments, suggestions, and supporting documentation for additions, deletions, or changes to this list are always welcome and encouraged, as is documentation of new or revised location data for any sensitive or watch-list taxa.
Changes to this list occur daily as new information is received or processed. While we intend to update this on-line list frequently, please contact our Data Manager if you require the most current information on any sensitive taxon. This on-line list must be scrolled to the right for complete viewing, and may be printed from your browser on letter-size paper in landscape format with 0.25-inch side margins. Click on the heading at the top of a column for an explanation of that column.
