Conserving boreal toads
Disease-resistant populations help prevent ESA listing
The eastern population of boreal toads lives in mountain ranges across Colorado, Wyoming, Montana and Utah. In November 2017, this species was found not warranted for protection under the Endangered Species Act, largely because of conservation efforts completed in Utah. Some of the factors that contributed to this success included:
- Surveys and monitoring have documented that boreal toad populations remain strong in most Utah mountain ranges.
- Populations in northern Utah appear to be more resistant to a widespread fungus-caused disease than some other populations, and they have persisted in spite of the fungus.
- Partners have completed key habitat projects — and more are underway — to protect boreal toad populations.
- A captive, back-up population has been established for Utah’s most at-risk boreal toad population.
Even though the 2017 decision ensured that boreal toads were not listed as threatened or endangered, biologists are still monitoring Utah populations and tracking toad sightings. ESMF funding, matched with federal State Wildlife Grant funding, has supported this fieldwork and monitoring.
