Since the 1980s, biologists have documented global declines in amphibian populations. Landscape alteration and habitat loss are known to play a major role in these declines. The aim of the U.S. Geological Survey's Amphibian Research and Monitoring Initiative (ARMI) is to assess the status of amphibian populations in the United States, determine causes for their decline, and provide information in support of amphibian conservation. EROS scientists involved with ARMI use satellite images and aerial photography in combination with weather, topographic, and land cover data to map and monitor landscape change that may impact amphibians, and to identify potential habitat that could support struggling populations.
