Final Report: GGNRA Tennessee Valley Seep and Stream Amphibian Surveys Big Lagoon Amphibian Surveys-Public version
Wood L and Fong D. 2004. Final Report: GGNRA Tennessee Valley Seep and Stream Amphibian Surveys Big Lagoon Amphibian Surveys-Public version. Saint Helena, CA
The California red-legged frog (Rana aurora draytonii) was placed on the Federal list of threatened species in 1996 (USFWS 1996), and critical habitat was proposed in 2001 and 2004 (USFWS 2001, USFWS 2004). The Recovery Plan for the California red-legged frog calls for, among other things, safeguarding of R. aurora draytonii habitat, control of non-native predators, and monitoring of known populations of the frog in core areas and high priority watersheds (USFWS 2002). Golden Gate National Recreation Area (GGNRA) lies within the Point Reyes Peninsula unit of critical habitat for the California red-legged frog. Due to interest in this frog as well as due to inventory and monitoring goals of the park, a study of amphibian use of selected springs, seeps, and streams in GGNRA was designed. The objectives of this study were to determine breeding and/or non-breeding use of selected springs and seeps by amphibians and reptiles and to describe any associations between sample site habitat conditions and use by amphibians and or reptiles. The study took place in Tennessee Valley, where spring/seep surveys and stream surveys were conducted, and at Big Lagoon, where marsh surveys were done.
