Listed Species of Montana

In order to receive protection under the Endangered Species Act, a species, subspecies, or distinct population segment must be placed on the Federal list of endangered and threatened wildlife and plants.  A species listed as "endangered" is one that is in danger of extinction throughout all or a significant portion of its range.  A species listed as "threatened" is one that is likely to become endangered within the foreseeable future throughout all or a significant portion of its range.  A "proposed" species is one that is proposed in the Federal Register to be listed under section 4 of the Endangered Species Act and a "candidate" is a species for which FWS or NOAA Fisheries has on file sufficient information on biological vulnerability and threats to support a proposal to list as endangered or threatened.
