NEW STUDY: ARMI paper documents surprising rates of amphibian declines in U.S.

We have summarized nine years of regional monitoring data to describe the rate at which amphibian populations have been changing at our survey sites across the country. The results, published in the scientific journal PLoS ONE, estimate declining trends for many species of frogs, toads and salamanders in all regions of the country. It is the first-ever broad assessment of amphibian populations in the United States, and the first quantitative estimate of trends for amphibian populations at a continental scale.
