armi.usgs.gov — The U.S. Geological Survey's Amphibian Research and Monitoring Initiative (ARMI) is a multidisciplinary effort to determine the status and trends of amphibians in the U.S., research the causes for amphibian declines, and provide scientific information to decision-makers to help halt or reverse declines. This website includes information on ARMI's More...

www.npwrc.usgs.gov — Interest in amphibians continues to rise as people become more aware of this fascinating group of animals. To the uninitiated all frogs may look alike; ditto for salamanders (in the same manner that beginning birders are overwhelmed by the immense variety of small brown birds). One of the purposes of this checklist and online identification guide More...

www.nwrc.usgs.gov — The south-central region includes the States of Texas, Oklahoma, Arkansas, Mississippi, and Louisiana. We are currently conducting research projects designed to monitor amphibians on Federal lands in these States and to research possible causes of declines in amphibian populations. These potential threats include loss or degradation of habitat, More...

fl.biology.usgs.gov — The objectives of Southeastern ARMI are to determine the status and trends of amphibian populations on DOI lands in the southeastern United States and U.S. Caribbean and to provide information useful in determining causes of declines should they be discovered. Meeting the needs and expectations of the Nation for monitoring the status of More...

www.frogweb.gov — Amphibian population declines are particularly serious in California, the Rocky Mountains, the Southwest, and Puerto Rico. This website addresses this concern by linking to resources about Amphibian Declines, Amphibian malformations, and resources to what can be done to help. There are additional links to species information and resources for More...
