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 heathy 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.

The functional effects of African lions on co-occurring carnivores differ across species pairs and with changes in resource availability and lion abundance The functional effects of African lions on co-occurring carnivores differ across species pairs and with changes in resource availability and lion abundance

Apex carnivores are known to regulate ecosystem structure and function, including via interactions with syntopic, competitively inferior carnivores. These effects may be dependent on relative carnivore density and resource availability or productivity. We investigated the functional effect of African lions as an apex carnivore on the presence of co-occurring large carnivore species...

An analysis of the linked decisions in the confiscation of illegally traded turtles An analysis of the linked decisions in the confiscation of illegally traded turtles

Over the last few decades, freshwater turtles have become more common in the illegal wildlife trade because of growing global demand. Illegally traded turtles may be intercepted by several different agencies with separate jurisdictions. When turtles are confiscated, uncertainties may make releasing them back to the wild difficult. We used tools from decision analysis to achieve the...

Evaluating the Risks of Tire-Derived Compounds to Fish in the Chesapeake Bay Watershed

Tires contain a chemical known as 6PPD which prevents them from quickly breaking down. Microscopic tire particles, generated mainly from the friction of tires on roads, release 6PPD-quinone (6PPDQ) when they come into contact with oxygen. During precipitation events, 6PPDQ can be washed off roads, harming fish in nearby waterways. In response to requests from fishery managers, the USGS is studying...

Using monitoring data to measure conditions over time in Chesapeake Bay streams

This study provides a comprehensive assessment of the health of streams throughout the Chesapeake Bay. Monitoring data were used to assess seven key indicators of stream condition, revealing consistent patterns of degradation in urban and agricultural areas. The findings offer critical insights that can inform watershed restoration efforts and improve long-term monitoring strategies.
