Boreal toads (Anaxyrus boreas), also known as western toads, have a range extending from southern Alaska to northern California and into Wyoming and Colorado west of the continental divide. These amphibians, nocturnal during the summer months and diurnal during the spring and fall, frequent mountain meadows and wetlands near aspen trees or Douglas fir and have been reported living as high as treeline.

Amphibian populations are declining worldwide. Boreal toads in the Crown of the Continent are under study to determine their adaptability to different hydrological conditions and response to fire in their habitat, as well, as they cope with the effects of climate change on wetlands.
