Which water body types are strongly associated with the life cycle needs of *Thamnophis sirtalis tetrataenia*?
Ponds, creeks, marshes, and associated riparian zones
The relationship between the San Francisco garter snake and water is highly specific, driven largely by its specialized diet. The snakes exhibit a strong association with aquatic environments characterized by slow-moving or still water. These suitable environments include natural features such as ponds, creeks, marshes, and the riparian zones directly bordering them. These specific water sources are essential because they host the necessary population of California red-legged frogs, which serve as the snake's primary food source. A body of water that is too fast-moving, too deep, or prone to drying up seasonally will not support the required prey base, making these specific water body types critical habitat components.
