The Desert Massasauga is the lone representative of the Sistrurus genus in Arizona, making it the most distantly related of all rattlesnake species in the state. It is small, usually tan, grey, or brown, and may superficially resemble a Prairie Rattlesnake to an untrained eye. In Arizona, the remaining tobosa grass habitat of the Massasauga is in decline due to development and grazing of cattle. While isolated populations continue to exist, numbers are in decline and eventual extirpation is likely. The Desert Massasauga is protected in Arizona from all forms of collection and harrassment, though habitat-conservation is likely the only means of saving this species in our state.
