The Yosemite toad (Anaxyrus canorus or Bufo canorus) is a species of the true toad family Bufonidae (Anaxyrus is a subgenus of true toads, genus Bufo). Endemic to the Sierra Nevada of California, the toads range is located primarily in the Sierra National Forest and Yosemite National Park of the central Sierra Nevada. However, the long lived amphibian maybe found north of Ebbet's pass around the Blue Lakes area or as far south as Spanish Mountain. A.canorus is listed as a species of concern by the California department of Fish and Game, as well as a candidate for listed protection under the Endangered Species Act.
The Yosemite toad utilizes montane meadows, sub-alpine meadows, riparian areas and the surrounding forest matrix as critical habitat during the various stages of its life history. Populations of these toads have been experiencing some declines in recent years. Factors such as climate change, habitat loss and pathogens may be contributing to the decrease of toad numbers. Anaxyrus canorus may be, more specifically, threatened by a fungus known as a chytrid. Cattle grazing has been suggested in the past as a contributor to the toad decline, however, recent research infers cows grazing montane meadows may be compatible with toad conservation efforts.
