Como Zoo Helping Preserve One Of The World’s Rarest Amphibians


A toad’ally awesome thing is happening at Como Zoo. As part of Como Zoo’s behind-the-scenes species preservation efforts,  Wyoming Toad tadpoles have been placed in oxygenated water, shipped overnight and were released on June 18, near the Mortenson Lake National Wildlife Refuge outside Laramie, Wyoming. This 1.5 ounce toad is classified as one of the four critically endangered amphibians found in North America and one of the rarest in the world.  Beyond sending tadpoles back to the wild, Bree Barney , Zookeeper will be going to Laramie, WY on July 20 and stay through the 26th to research the progress and conservation of this species in it’s natural habitat. Bree will be conducting surveys of land and toads to see progress and endangered state.

Native to the Laramie Basin in Wyoming, this toad was placed on the endangered species list in 1984, and was feared to be extinct. Researchers located the last surviving toads near Lake Mortenson in the late eighties, and by 1996 began an aggressive species preservation plan to save the toad. Como Zoo has joined forces with eight other zoos including the Kansas City and Detroit Zoos as partners in a captive breeding program that now reintroduces Wyoming tadpoles and toads to the wild every year.

As part of the project, Como received adult Wyoming toads that now live in a specially retrofitted room in Como’s Animal Support Building. “The Wyoming toads play an important part in Como’s mission. Since these projects usually go on behind the scenes, people are often surprised to hear how involved Como Zoo is in species preservation,” says Michelle Furrer, Como Campus Director. “But Como Zoo, along with many other zoos, are always striving to make a difference in conservation.’’

To be eligible to participate in the Species Survival Plan (SSP) each institution must meet certain criteria. The four criteria relevant to preventive medicine husbandry and space allotment include the following:

1) Candidate must isolate Wyoming toads from other amphibians in the collection through designated biosecure housing and quarantine.
2) Candidate must commit space for at least four age cohorts totaling 20-40 toads, breeding transfers and pre-release tadpole holding.
3) Candidate must receive USFWS Endangered Species permit to acquire the federally listed toad prior to participation in the SSP.
4) Candidate must comply with the service and SSP guidelines for the recovery program.

It’s a privilege for an institution to be able to participate in species recovery efforts. It comes with much responsibility, and often an additional investment in resources including additional staff and/or construction of biosecure facilities. A generous grant from the Frog Crossing Foundation allowed Como Friends, the nonprofit partner of Como Park Zoo & Conservatory, to provide the retrofitting necessary to give Como Zoo’s new Wyoming toads the optimal environmental controls, a hibernation chamber critical to stimulate the toads’ reproductive cycle, and additional AZA staff training to help ensure the success of this species preservation project.
