Updates to Species and State Pages

Species pages for the Southern Durango Spotted Garter Snake and the Narrow-headed Garter Snake have received substantial updates. So have the state pages for Arizona and New Mexico, which add native garter snakes’ legal status. And I’ve created a page for a newly described species, the Madrean Narrow-headed Garter Snake. This is all in response to a 2011 study splitting the Mexican populations of the Narrow-headed Garter Snake into separate species.
