Description
Amphibian populations are declining globally (Jennings and Hayes 1985, Beebee
et al. 1990, Blaustein and Wake 1990). Disease, introduced predators, ultraviolet
radiation, pollution, environmental change, and habitat loss and degradation have been
suggested factors responsible for amphibian population declines (Jennings and Hayes
1985, Beebee et al. 1990, Laurance et al. 1996, Pounds et al. 2006). However, the
relative importance of each potential factor is often unknown in specific cases. Because
the processes that underlie amphibian declines are not well understood, collaborative
efforts, such as the North American Amphibian Monitoring Program (NAAMP), have
been developed to collect basic ecological data, and to systematically monitor amphibian
population trends. Despite efforts such as the NAAMP, there are still many areas where
amphibian surveys have not been conducted and little is known about local populations.
