ARMI

The USGS Eastern Ecological Science Center (EESC) is rooted in a proud tradition of service to the nation—advancing science that informs the conservation and management of fish, wildlife, and habitats across the eastern United States and beyond. Our mission is clear: deliver reliable, partner-driven science that supports natural resource decisions today, while ensuring these resources remain...

Decision analysis is widely used in business applications to improve cost saving and increase efficiency under uncertainty. Scientists at the U.S. Geological Survey Eastern Ecological Science Center (EESC) include world-renowned experts who use data, mathematics, statistics, and computer science to help frame and solve decision problems to support U.S. national security, public health, wildlife...

In 2013, the Salamander Population and Adaptation Research Network started as a partnership between researchers at Penn State University and the USGS Northeast Amphibian and Research Monitoring Initiative with the intention of creating a research network to address adaptation and population dynamics across multiple scales. Our goals are to understand impacts of land use and weather conditions on...

In 2004, the Northeast Amphibian Research Monitoring Initiative (NE ARMI) in collaboration with National Park Service and US Fish and Wildlife Service initiated a region-wide study on the distribution of vernal pools and estimate the proportion of pools that were occupied by pool-associated amphibians (specifically, wood frogs, Lithobates sylvaticus, and spotted salamanders, Ambystoma maculatum).

The U.S. Geological Survey’s Eastern Ecological Science Center is home to the Northeast Amphibian Research and Monitoring Initiative (NEARMI), one of 7 ARMI regions across the United States. NEARMI works on public lands in thirteen states from Maine to Virginia, including many National Parks and National Wildlife Refuges.

We are working closely with multiple partners to provide updated information, model potential outcomes, and identify key uncertainties relevant to amphibian and reptile species proposed for listing in the northeast US. We also provide timely science to partners to assist in recovery of listed species, which may involve field research, data analysis, or decision support.

The Shenandoah salamander is listed as an endangered salamander that is at risk of extinction due to its small, high-elevation range, competition with the co-occurring red-backed salamander, and the predicted habitat changes in the Appalachian mountain range. We are working with multiple partners to understand the current status of the species, predict future status, and continually engage...
