Current Research

Garth works with Dr. Karen Pope studying the population dynamics of Cascades frogs in the Trinity Alps and the Lassen region of California with a primary focus on the amphibian disease, chytridiomycosis. Garth is involved in field experiments and statistical analysis to determine the effects of the disease on the frogs and to find ways to mitigate those effects. Garth is also involved in a research program working on meadow restoration projects to improve conditions for biodiversity, such as a beaver restoration study in Childs Meadow, just south of Mt. Lassen.

Past Research

Previously Garth worked with Dr. Hartwell Welsh conducting research to document the ecological roles of forest amphibians and reptiles and their use as bio-indicators of ecosystem health. Study areas included the Mattole River basin, in the South Fork Trinity River, and the Mill Creek watershed near Crescent City, California. Other research focuses included a study on the effects of an altered flow regime on western pond turtles from a dam on the Trinity River, garter snake habitat selection on Hurdygurdy Creek, and the effects of stream sedimentation on aquatic amphibians in Prairie Creek Redwoods State Park. Garth has also worked with other researchers such as Dr. C. J. Ralph conducting marbled murrelet and songbird surveys on timber company lands, Rod Nakamoto on a summer steelhead temperature study in the New River, and a pine marten habitat use study using telemetry in the Lassen region. Prior to that Garth worked with hydrology researchers studying the effects of timber harvesting on hillslope processes and stream sedimentation in Prairie Creek Redwoods State Park and in Caspar Creek near Fort Bragg, California.
