Western Pond Turtle


The western pond turtle (Clemmys marmorata) is listed by the federal government and the State of California as a species of special concern.  Our focus on the species begins with offering workshops on the basic ecology and conservation of the species, and we will progress with future workshops specifically addressing habitat restoration and other actions necessary for recovering healthy populations for the species.
