Response of the Giant Garter Snake to Water Primrose Removal at the Cosumnes River Preserve

Hansen, E.C., H. McQuillen, S. Sweet, S. Gala, and J. Marty.  2010.  Response of the Giant Garter Snake (Thamnophis gigas) to Water Primrose (Ludwigia hexapetala) Removal at the Cosumnes River Preserve. Report prepared for the Central Valley Habitat Improvement Act Conservation Program.  December 29, 2010.

Producing positive results, this study tested whether restoration of open-water foraging habitat would result in the return of giant garter snakes to previously occupied areas of Snake Marsh. Combined with detailed hydrologic and vegetation reports, this study provided valuable recommendations for long-term management at the Preserve. (2009-2010)
