Abstract
Ranid frogs (Rana catesbeiana, R. chiricahuensis, R. yavapaiensis), garter snakes (Thamnophis eques, T. marcianus) and Sonoran mud turtles (Kinosternon sonoriense) were surveyed. Distribution of the introduced bullfrog R. catesbeiana was negatively correlated with distributions of the 2 leopard frogs and garter snakes. The hypothesis that bullfrog predation caused decline of a native wetland herpetofauna is supported by data on bullfrog diet, on garter snake, leopard frog and mud turtle population structure, and natural history observations on the snakes. Experimental removal of bullfrogs has been initiated at the San Bernardino National Wildlife Refuge. -from Authors
