Eastern Garter Snakes have a number of predators, including birds of prey, mammals, and other snakes. This species is also threatened by habitat destruction and fragmentation, as well as the introduction of invasive species. The Eastern Garter Snake is also often killed by humans, either intentionally or unintentionally, and is often viewed as a pest species. However, this species plays an important role in its ecosystem, and efforts should be made to conserve and protect it.
