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.

What is the United States doing about amphibian deformity and decline issues?
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 Amphibian Research and Monitoring Initiative (ARMI). The main...
What causes deformities in frogs, toads, and other amphibians?
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...
Why are amphibian populations declining?
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...
