The USGS Amphibian Research and Monitoring Initiative (ARMI) is designed to determine where populations of amphibians are present, to monitor specific apex populations, and to investigate potential causes of amphibian declines, diseases, and malformations. The Northeast Region of ARMI encompasses thirteen states (Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia) and the District of Columbia.
Dr. Evan H. Campbell Grant at the USGS Patuxent Wildlife Research Center in Laurel, Maryland, coordinates ARMI activities in the Northeast by conducting and developing amphibian research and monitoring projects.
The ARMI program is based on a three-tiered approach, with extensive broad scale sampling, mid-level sampling, and intensive sampling and research at Apex Sites. Information from surveys in the Northeast will be used to determine the proportion of surveyed areas that are occupied by various species of amphibians and to estimate amphibian population sizes and trends over space and time.

The areas of the United States that are most at risk of a potentially invasive salamander fungus are the Pacific coast, the southern Appalachian Mountains and the mid-Atlantic regions, according to a recently published U.S. Geological Survey report.
A deadly fungus causing population crashes in wild European salamanders could emerge in the United States and threaten already declining amphibians here, according to a report released today by the U.S. Geological Survey.
