There is only one native turtle on the Reserve, the western pond turtle (Clemmys marmorata). These turtles are found around the edges of the Berryessa Reservoir most of the year. However, they probably lay eggs on the Reserve. A female was observed in Decker Canyon about 800 m from the edge of the reservoir.
