Narrow-headed gartersnake conservation
Recent surveys have suggested that populations of Narrow-headed gartersnakes have declined by at least 50% over the last 20 years. The Narrow-Headed Gartersnake is not listed under the Endangered Species Act, but because it is declining it has been listed as a species of special concern by Arizona, New Mexico, and the U.S. Fish and Wildlife Service. One of the main reasons for this decline is the presence of invasive species. Bullfrogs and crayfish consume young snakes. Sport fish like sunfish and catfish have bony spines that can cause injury when snakes try to swallow them. Habitat has also been lost due to the damming and diversion of waterways.
