What is the ideal shallow water depth, measured in centimeters, required near pond edges for SFGS foraging between May and July?
Answer
Less than 5 cm deep
The aquatic habitat requirements for the San Francisco garter snake are extremely specific, dictated by the need to access its specialized prey base, particularly metamorphosing amphibians, during the summer months. For the snakes to effectively forage and access prey like the California Red-Legged Frog when they are transitioning from aquatic to terrestrial life, the water near the edges must be very shallow. The precise ecological requirement specified for this critical period, which runs from May through July, is that the water depth must ideally be less than 5 cm deep, facilitating easy access for the snakes while ensuring adequate cover provided by emergent vegetation like cattails.
