Nevada Natural Heritage Program
NEVADA AT-RISK PLANT AND LICHEN
TRACKING 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 235 plant and lichen taxa that appear, based on the best available scientific information, to be at risk of extinction or serious decline. Taxa considered at-risk and actively inventoried by NNHP typically include those with federal or other Nevada agency status of Endangered, Threatened, or Sensitive, and those with Global ranks (Grank 1-3) or declining trends indicating some level of range-wide imperilment. In general, an at-risk 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 at-risk tracking list in the future, or that recently have been removed from the at-risk tracking list. NNHP passively accumulates data for watch list taxa.
NOTICE: our placement of any species on any list is for informational and advisory purposes ONLY, and does not constitute a regulatory action by the Nevada Natural Heritage Program.
Older editions of this list remain available on-line. The parallel Detailed Rare Plant and Lichen List may be more up-to-date, and provides additional information on Nevada Native Plant Society ranks; family names, observation history, habitat, range, trends, and land management for all at-risk 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 at-risk taxa identified in Nevada. We currently have no information on which algae or non-lichenized fungi may be at-risk in the state, and are just beginning to develop such 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 at-risk 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 at-risk taxon. This on-line list may need to 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.
