Book Description
In 1991, the Herpatology Laboratory at Idaho State University began a collaborative project with the National Park Service and U.S. Fish and Wildlife Service to assess the occurrence and status of amphibians in the Greater Yellowstone Ecosystem. The program was expanded in 2000 and was fully implemented by 2007.

Book Description
Concerns about amphibians have escalated since population declines became apparent in diverse areas around the world in the 1980s (Collins and Storfer 2003). Systematic examinations have revealed that in some regions, including North America, rapid declines probably began around the middle of the 20th century, with the rate of decline increasing in the 1990s (Houlahan et al. 2000; Alford et al. 2001). Worldwide, 32% of amphibian species are now threatened with extinction, while 43% exhibit some form of population decrease (Stuart et al. 2004). Amidst the rapid and general decline in global biodiversity, amphibian population extinctions and declines are particularly alarming because they are occurring not only where habitat has been lost, but also in natural, protected areas.

Book Description
The national parks within the Greater Yellowstone Ecosystem (GYE) provide an opportunity to monitor amphibians within a relatively intact ecosystem, at spatial and temporal scales that can provide important insights about the status of regional amphibian populations and global declines of amphibians. The Greater Yellowstone Network (GRYN) amphibian monitoring program is the only long-term amphibian monitoring program in the GYE that consistently looks at multiple sites across the ecosystem.

Book Description
The Greater Yellowstone Network (GRYN) was established by the National Park Service Inventory and Monitoring (I&M) Program in 2000 to help enhance the scientific basis for stewardship and management of natural resources in Bighorn Canyon National Recreation Area, Grand Teton National Park including the John D. Rockefeller, Jr. Memorial Parkway, and Yellowstone National Park.

Book Description
Monitoring of natural resources is crucial to ecosystem conservation, and yet it can pose many challenges. Annual surveys for amphibian breeding occupancy were conducted in Yellowstone and Grand Teton National Parks over a 4-year period (2006?2009) at two scales: catchments (portions of watersheds) and individual wetland sites. Catchments were selected in a stratified random sample with habitat quality and ease of access serving as strata. All known wetland sites with suitable habitat were surveyed within selected catchments. Changes in breeding occurrence of tiger salamanders, boreal chorus frogs, and Columbia-spotted frogs were assessed using multi-season occupancy estimation. Numerous a priori models were considered within an information theoretic framework including those with catchment and site-level covariates. Habitat quality was the most important predictor of occupancy. Boreal chorus frogs demonstrated the greatest increase in breeding occupancy at the catchment level. Larger changes for all 3 species were detected at the finer site-level scale. Connectivity of sites explained occupancy rates more than other covariates, and may improve understanding of the dynamic processes occurring among wetlands within this ecosystem. Our results suggest monitoring occupancy at two spatial scales within large study areas is feasible and informative.
