Which dense plants are frequently noted components of the preferred terrestrial structure for *T. s. tetrataenia* cover?
Gorse and poison oak
While the San Francisco garter snake utilizes aquatic areas for breeding and feeding, it spends the majority of its time on land utilizing dense terrestrial cover for concealment from predators, primarily raptors, and for thermoregulation. The preferred structure for this concealment is often provided by dense thickets of vegetation. Sources frequently identify both native and non-native species fulfilling this role, with Gorse and poison oak specifically mentioned as common components that offer excellent hiding places. It is crucial to note that the functional attribute desired is the structural density of the cover, regardless of whether the plants are native or pose potential hazards, like poison oak, to human surveyors.
