A San Francisco Airport Site Is Crawling With Snakes—And That's a Good Thing

The endangered San Francisco garter snake has made a comeback due to conservation efforts at the San Francisco International airport. They built ponds and wetlands to make the conditions ideal for the snake to thrive and as a result, approximately 1,300 snakes call the property home. While there are still issues with invasive plants and industrial runoff polluting the area, the ecological improvements have helped the snake population’s rebound.
