Vertebrate Animal Species of Concern

The links in the left side bar will take you to lists of vertebrate animals that WYNDD tracks (or watches for potential tracking) because they are considered to be of extremely high, high, or medium conservation concern within the state of Wyoming. All species on this list are assigned ranks based on standard methodology for determining risk of extinction within Wyoming (see Keinath and Beauvais 2003). Tracked species include those ranked S1, most that are ranked S2, and select species ranked S3 if they also have a high Wyoming Contribution Rank or are experiencing substantial threats (see Heritage Rank Definitions). Watched species, or those of potential concern, are generally those that currently appear secure in Wyoming but exhibit some vulnerability that suggests they could become a conservation priority in the future. Species of potential concern are included in the online tracked list, but differentiated with row highlighting and text. The status of species are periodically reviewed and updated as appropriate.

These lists have no status under state legislation, though S-rank values are sometimes cited in policies, and referenced in development of sensitive species lists by federal land-management agencies. In general, federal sensitive species list criteria are narrower and more geographically restricted than criteria used for inclusion on the Wyoming Species of Concern List. The list contents and S-rank values are based on factors considered as the state level, not within any particular management jurisdiction. Wyoming contribution ranks are calculated as an alternative score that represents the relative contribution of species' status in Wyoming over its rangewide status.

WYNDD has generated species assessments for many species on these lists, which provide detailed discussions of their biology and conservation concerns (see the Species Assessment page). We are in the process of creating brief Species Abstracts for all tracked species that will concisely state major biological information (e.g. habitat) and conservation concerns.
