Species of the Day – Wyoming toad (Anaxyrus baxteri)

December 13, 2012


The Wyoming toad is an extremely rare amphibian that exists only in captivity and within Mortenson Lake National Wildlife Refuge in the U.S. state of Wyoming.The Wyoming toad was listed as extinct in the wild since 1991.

Common in the 1950s, the Wyoming toad experienced a sharp decline during the 1970s leading to an endangered species listing and it was believed the toad was extinct by 1980. The toad was later rediscovered in the wild in 1987 along the shores of Mortenson Lake

Recovery programme using captive-bred animals and re-introductions, is being implemented. Recently acquired a 1,800-acre tract at Mortensen Lake and has arranged a conservation easement with an adjacent landowner. The success of the recovery programme probably depends on finding some way to combat chytridiomycosis in the wild.
