Some more information to help us understand the U.S. Fish and Wildlife Service’s proposal to add the Mexican and Narrow-headed Garter Snake to the federal endangered species list as Threatened species. The Payson Roundup’s Pete Aleshire provides some necessary context for the proposal (the snakes had been identified as at-risk for a decade or more) and looks at the implications for federal land and private property. Sandra Postel, writing on National Geographic News Watch, looks at the snakes in the context of the health of the Gila River.
