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 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.

In response to indications of worldwide declines in amphibian populations, Interior Department agencies were directed to initiate a national program of amphibian monitoring, research, and conservation. There is an urgent need to determine the scope and severity of the problem and to investigate causes. As a result, the USGS formed the National Amphibian Research and Monitoring Initiative (ARMI)...
Malformed frogs first came to national attention in 1995. Since that time, reports of malformed frogs and other amphibians have increased dramatically. Malformations have been reported in at least 44 states and in more than 50 species of frogs and toads. Multiple limbs, missing limbs, and facial abnormalities are the main malformations seen.Frog malformations are the result of environmental...
More than 6,000 amphibian species exist worldwide, with approximately 300 of them found in the United States. The USGS is the lead agency for the Amphibian Research and Monitoring Initiative (ARMI), a program of amphibian monitoring, research, and conservation that was established in response to the worldwide decline of amphibian species.
Research suggests that even though amphibians are severely declining worldwide, there is no smoking gun—and thus no simple solution—to halting or reversing these declines.Though every region in the United States has suffered amphibian declines, threats differ among regions. They include:Human influence from the Mississippi River east, including the metropolitan areas of the Northeast and the...
