What taxonomic classification issue sometimes complicates the federal endangered status of *Anaxyrus baxteri*?

It is sometimes treated as a subspecies of the Western Toad (*Anaxyrus boreas*).

Although *A. baxteri* is recognized federally as an endangered species, its precise taxonomic standing is subject to scientific discussion or debate. While it possesses unique genetic and physical characteristics that affirm its species status, some views suggest that it should be classified merely as a subspecies rather than a fully distinct species. This classification specifically relates to the Western Toad, identified as *Anaxyrus boreas*. The text indicates that achieving precise taxonomic agreement on this matter is critical, as the conservation status—federally endangered—rests partly on its confirmed status as a distinct species.
