Across the country, USGS scientists research amphibians to help other agencies manage this historically underappreciated and now declining group. Our scientists have learned that no single threat explains global amphibian declines; instead, a variety of local and global factors are contributing. Habitat loss, disease, contaminants, and other threats are all part of the pattern.
