Mortenson Lake National Wildlife Refuge is closed to the public due to the endangered status of the Wyoming toad.
However, Wyoming Game and Fish Department has public access nearby at Meeboer Lake, Gelatt Lake, and Twin Buttes Public Access Areas.
Location and Contact Information
The last-remaining wild Wyoming toad population survives in a tiny oasis at Mortenson Lake National Wildlife Refuge, which was established in 1993 specifically to protect the two-inch-long toad. Here the toad lives in isolation—hidden from view in the shortgrass prairie communities within the river basin, in the flood plain, and in the ponds, oxbows, wetland andhabitats on the refuge. From 1985 to 1987, the species was presumed extinct; however, the discovery of a viable population in 1987 sparked new hope. However, in 2011 only one Wyoming toad was able to be found in the wild. Thus a new approach of habitat management and captive breeding began and has yielded better results. The Wyoming toad persists with the unfortunate title as the most endangered amphibian in North America, but we are learning more about the species and its habitat needs.
