Summary
edit.jpg&action=edit§ion=1){kind=link}
| Description | The American bullfrog is native to the eastern United States. The date of first introduction to Arizona is unknown, but they were introduced to California in the 1890s, and by the late 1920s the species was reportedly common on the Colorado River at Yuma. Bullfrogs are awesome and voracious predators. Predation by bullfrogs has contributed to the decline and extirpation of native leopard frogs and garter snakes. They are one of the biggest challenges to the recovery of many native aquatic species. Elimination of bullfrog populations is achievable in small, manageable wetlands, but is difficult or impossible in lakes, rivers, agriculture, and other complex habitats. Bullfrogs are also a vector for chytridiomycosis, a fungal disease that is killing frogs and toads around the globe. Areas such as the Kaibab National Forest were likely occupied by native northern leopard frogs prior to bullfrog invasions. The Forest Service, Arizona Game and Fish Department, and U.S. Fish and Wildlife Service are working together to re-establish northern leopard frogs on the Kaibab National Forest.
