Wyoming Toad

Wyoming Toad Recovery Program

One of the most endangered amphibians in the world, the Wyoming toad was once abundant in Wyoming's wetlands. But increasing pollution from pesticide runoff, habitat destruction, fungal disease and acid rain have all had disastrous consequences for this toad.

In 1994, Wyoming toads were extinct in the wild, and only one captive population remained. That population became the foundation for a captive breeding program in nine zoological and governmental facilities, producing tadpoles and toadlets for reintroduction to the wild.

Cheyenne Mountain Zoo's breeding program produced extraordinary results in its first year, 2004: More than 1,000 tadpoles came from just two breeding pair. Of those, five toadlets have been kept at the Zoo's Amphibian Propagation Center to be raised for future breeding, while the remaining tadpoles were released into their natural habitat at Lindzey Ranch in Wyoming.
