Bon aii
Litt]e is known about the biological requirements of the bonytail, as the
species has drastically declined in numbers in the Upper Basin shortly after
1960. Until recently, the Service considered the species extirpated from the
Upper Basin; however, a recently collected specimen which exhibits many
bonytail characteristics could indicate a small, extant population
(Kaeding et al. 1986). It is thought that, should this species persist in the
Colorado River, the preferred habitat would be in the larger river reaches.
