The only Wyoming toads in the world live in Mortenson Lake National Wildlife Refuge in southeastern Wyoming, where they were common until the 1970s, hopping around at the edges of creeks, ponds, and small lakes. From: gizmodo.com

GR:  The toad was saved by captive breeding and is being reintroduced to its former habitats, but it still faces the great danger of the chytrid fungus that we have spread around the planet.  The disease has probably reached Wyoming by now, and we should know within a few years if the Wyoming toad is immune enough to survive.
