Details of this ranking system are in strategies. Such information is especially vital to Keinath and Beauvais (2003) and Fertig and Heidel management plans that strive to integrate the (2003). conservation of rare species with development of natural The list format has been changed to provide readers resources. with more species-specific information while still This publication provides the most complete maintaining a concise layout.

Animal Species of Potential Concern – ALL TAXA

Please note that not all species on the potential concern list have been fully incorporated into the new ranking system. S-ranks given in square brackets (e.g., [S3B]) are carried over from the 1999 list and S-rank reasons in square brackets are from the range comments section of the 1999 list. A designation of Not Ranked (NR) in the Wyoming contribution rank columns means that these species have not yet been assigned a Wyoming contribution rank. All these fields will be updated in future lists, at which time decisions may be made to elevate or remove certain species from this list.
