This Sunday an adult female giant garter snake (Thamnophis gigas; GGS) was captured at Westervelt’s Grasslands Mitigation Bank by permitted biologist and species expert Eric Hansen and his crew. The 273-acre Grasslands Mitigation Bank was established in 2015 and is located next to the Volta Wildlife Area, which supports one of the few known GGS populations in the San Joaquin Valley Basin.

GGS are considered threatened under the California and federal Endangered Species Acts. The captured GGS was healthy and weighing over 300 grams (that’s more than a half-pound of snake!). Her presence on the Bank signifies the Grasslands Mitigation Bank is successfully providing this species with suitable habitats, including include open water, emergent marsh, and uplands.
