Eastern Ecological Science Center

The USGS Eastern Ecological Science Center (EESC) strives to provide world-class science to inform natural resource decisions that preserve and enhance our quality of life. 

The land and water we live on and around shapes our lives. We share responsibility for the healthy fish, wildlife and landscapes that are assets to current and future generations.

EESC works directly with managers of our shared natural resources to provide the unbiased scientific tools, research and innovations needed to make informed decisions in today’s complex and rapidly changing conditions.

EESC’s broad expertise spans from mountain streams to deep oceans and the lands in between, supporting stewardship of a wide range of species and habitats.

Unique facilities in Maryland, Massachusetts and West Virginia help EESC deliver the reliable, actionable science that partners need to effectively conserve our treasured natural resources.

Decision analysis of long-term research and monitoring investments for the Upper Mississippi River Restoration program Decision analysis of long-term research and monitoring investments for the Upper Mississippi River Restoration program

Congressional authorization of the Water Resource Development Act of 2020 increased funding for the Upper Mississippi River Restoration (UMRR) program and its Long Term Resource Monitoring (LTRM) element. With adequate resources there is an opportunity for LTRM to expand its understanding of the Upper Mississippi River System, address unmet partner information needs, and better inform...

Ecological transformations of coastal wetlands of the conterminous United States in response to contemporaneous sea-level rise Ecological transformations of coastal wetlands of the conterminous United States in response to contemporaneous sea-level rise

Coastal wetlands are among the most important ecosystems on the planet but are increasingly imperiled by accelerating sea-level rise (SLR). In the past, biogeomorphic feedbacks have allowed coastal wetlands to adjust vertically and persist through periods of accelerated SLR. Recent rates of SLR are faster than any in recent geologic history, making the fate of coastal wetlands highly...

Long-term predictive modeling of stream condition suggests wide-spread changes within the Chesapeake Bay Watershed, USA Long-term predictive modeling of stream condition suggests wide-spread changes within the Chesapeake Bay Watershed, USA

Stream ecosystems worldwide face ongoing degradation, underscoring the urgent need for conservation and restoration. Regional analyses of stream condition have been limited by sparse spatial and temporal data, particularly at long time scales. To address this gap, we used observed data to predict annual biological condition for 360,893 small, nontidal stream reaches in the Chesapeake Bay...

Osprey (Pandion haliaetus) Population and the Availability of Menhaden (Brevoortia tyrannus) as Their Food Source in Chesapeake Bay: Historical and Present-day Comparison

USGS is collaborating with many biologists in analysis of data on osprey ( Pandion haliaetus) and their prey (menhaden, Brevoortia tyrannus, and other species of fish) in the middle and lower Chesapeake Bay and its tributaries. The data compiled and collected will help determine if a lack of menhaden or other environmental factors are affecting osprey reproductive success in portions of the...

Not All PFAS Are Alike: Fish Responses Reveal The Importance Of Real-World Mixtures

A USGS study demonstrates the importance of monitoring not just the amount of PFAS in groundwater, but the PFAS mixture present. Building on two decades of experience conducting mobile laboratory experiments, USGS researchers applied this approach at a contaminated fire training area to evaluate how fish respond to complex PFAS mixtures, providing important scientific evidence that can improve how...

Advancing the Environmental DNA Toolkit for Ecosystem Monitoring and Management

The emerging field of Environmental DNA (eDNA) analysis allows characterization of species presence and community biodiversity by identifying trace amounts of genetic material left behind as organisms move through their environments. EESC scientists have been using eDNA technologies to detect native and rare species and as community biomonitoring tools.
