Species of Concern


Mammals | Birds | Amphibians | Insects | Flowering Plants
Fishes | Snails | Crustaceans


The following list includes some (but not all) of the Species of Concern in Region 3 and actions that have or are being taken to document their status or conserve the species. As time and budget allows, species and additional information will be added to this list.


"Species of concern" is an informal term that refers to those species which Region 3 believes might be in need of concentrated conservation actions. Such conservation actions vary depending on the health of the populations and degree and types of threats. At one extreme, there may only need to be periodic monitoring of populations and threats to the species and its habitat. At the other extreme, a species may need to be listed as a Federal threatened or endangered species. "Species of concern" receive no legal protection and the use of the term does not necessarily mean that the species will eventually be proposed for listing as a threatened or endangered species.


Region 3 is the lead region unless noted otherwise. Abbreviation indicates the lead Field Office within Region 3 (e.g., TCFO).
