Amphibian decline in Yellowstone National Park.

Patla, Debra A.; Peterson, Charles R.; Corn, Paul Stephen. 2009. Amphibian decline in Yellowstone National Park. Proceedings of the National Academy of Sciences, USA. 106(9): E22.

We conduct long-term amphibian monitoring in Yellowstone National Park (YNP) (1) and read McMenamin et al.'s article (2) with interest. This study documents decline in the extent of seasonal wetlands in the Lamar Valley of YNP during extended drought, but the conclusion, widely reported in the media, of "severe declines in 4 once-common amphibian species," is unsupported. This study wrongly defines sites occupied by one nonbreeding individual as "populations."

Keywords: amphibian monitoring, seasonal wetlands, Lamar Valley, Yellowstone National Park
