Hansen, E.C.  2008.  Implementation of Priority 1, Priority 2, and Priority 3 Recovery Tasks for Giant Garter Snake (Thamnophis gigas) – continuing Surveys in Merced County, California, with an Expansion to Northern Fresno County.  Report prepared for the U.S. Fish and Wildlife Service pursuant to FWS Agreement No. 802707G112, April 15, 2008.
