  History
Continued . . .

It was first reported to occur in Wyoming in 1946, but by the mid to late 1970s, the population drastically declined and by 1980 was thought to be extinct. The Wyoming toad was listed as a federally endangered species in 1984.

A small population of toads was discovered at Mortenson Lake in 1987, and a recovery team was established in hopes of preventing extinction of the toad. The Nature Conservancy purchased the land originally, and the U.S. Fish and Wildlife Service purchased it later. The Refuge was established in 1993 to protect the Wyoming toad's last known population.
