Development of a Multimetric Index for Integrated Assessment of Salt Marsh Condition in the Northeast Coastal and Barrier Network

The Challenge: The integrity and sustainability of salt marshes in National Park units of the Northeast Coastal and Barrier Network (NCBN) are severely threatened by human activities. These marshes provide critical fish and wildlife habitat and essential ecosystem services in the northeastern coastal zone, and are a high priority for NCBN Vital Signs monitoring. Biennial monitoring of nekton (...

Recovery of Eelgrass (Zostera marina L.) in Casco Bay, Maine, Following Destruction by European Green Crabs

The Challenge:  Eelgrass provides essential functions to the ecology and economy of Maine’s coastal zone. When over half the eelgrass in Casco Bay, Maine, disappeared between 2012 and 2013, USGS experimental evidence identified disturbance from invasive European green crabs as the leading cause. Loss of vegetation is expected to precipitate a range of impacts, including reduced fish and...

Integrating Estuarine Water-Quality Data in Northeastern National Parks

The Challenge: Estuaries in northeastern states are severely threatened by the adverse impacts of nutrient over-enrichment. USGS led the development of a vital-signs protocol to monitor estuarine nutrient status in northeastern National Parks, and monitoring has been operational in coastal parks from Massachusetts to Virginia since 2006. Monitoring results must be synthesized and interpreted...

Variation in Nitrogen Isotope Ratios of Eelgrass to Detect Trends in Estuarine Nutrient Status

The Challenge: Seagrasses are productive and important components of shallow coastal waters, and they have suffered extensive declines worldwide. Because seagrasses are directly in the path of watershed nutrient inputs, a major cause of habitat loss is coastal development and consequent water quality degradation. Improved approaches for detecting threats of nutrient enrichment are paramount to...

Use of Structured Decision Making to Optimize Salt Marsh Management Decisions at Northeastern National Wildlife Refuges

The Challenge: The U.S. Fish and Wildlife Service (FWS) needs tools to inform decisions regarding the management and restoration of salt marsh ecosystems on northeastern National Wildlife Refuges. Previously, we developed a structured decision making (SDM) framework for optimizing refuge management decisions. This SDM framework served as the foundation for FWS to implement a consistent...

Seabird Research Program

The Seabird Research Program at PWRC is focused on studying the ecology of species present across the Atlantic Coast. This program was a natural progression of PWRC's historic work studying the coastal ecology of wildlife in and around the Chesapeake Bay. We now focus on the three key areas on a variety of species: physiology, avoided bycatch, and movement ecology.

Survival and Recruitment of Common Eiders in the Gulf of Maine

The Challenge: Common eider numbers are declining throughout most of their range. The cause of this decline is not know, but poor recruitment, declining food resources, hunting, poor survival are possible causes. Research goals of this project focus on understanding the effects of hunting and predation on survival and recruitment rates of American common eiders (Somateria mollissima) in the...

Response of Avian Community to Forest Management on Moosehorn National Wildlife Refuge

The Challenge: Research goals focus on measurement of direct effects of various habitat management techniques for game species on neotropical migratory birds. Analyses are ongoing to determine if avian species richness, diversity, and relative abundance of land birds has changed at Moosehorn National Wildlife Refuge as a result of habitat management; determine if the structure of the avian...
