Over the past several decades, scientists, natural resource managers, and the general public have become increasingly aware of, and concerned for the impaired health of the Chesapeake Bay.

Harpers Ferry National Historical Park provides a wealth of natural resource values, including riparian habitats, floodplains, agricultural fields, geologic exposures, rare limestone glades, developed areas, and upland forests. These resources were assessed using the Vital Signs framework. Overall, the natural resoures in Harpers Ferry National Historical Park are in degraded condition and are under threat from surrounding land use, regionally poor air quality, and overpopulation of deer.

Catoctin Mountain Park provides a wealth of natural resource values, largely resulting from the maintenance of forest and wetland habitats. These resources were assessed using the Vital Signs framework. Overall, the natural resoures in Catoctin Mountain Park are in moderate condition but are under threat from surrounding land use, regionally poor air quality, and overpopulation of deer.

Chesapeake and Ohio Canal National Historical Park provides a wealth of natural resource values, due to its location spanning four physiographic provinces. These resources were assessed using the Vital Signs framework.

This book is for environmental managers. Physically, our environment gives us everything we need, but then there are things that we just 'want', so as our wants grow, the demands we place on our environment increase even more rapidly. As awareness of these environmental pressures grow, so too do the numbers of people working in environmental fields. People can burn out trying to balance their desire to protect the environment with a wide variety of demands. This book tells the story of Prof.

The America's Watershed Initiative Report Card project continued with a regional workshop for the Ohio River Basin, held near Cincinnati, Ohio, on December 12–13, 2013. At the workshop, stakeholders and experts from social, economic, and environmental sectors identified easily understood and transparent ways to measure status and trends for the Ohio River Basin in relation to six broad goals.

Anthropogenic nitrogen contributes to water quality degradation, but it is difficult to distinguish sources once they are mixed in coastal ecosystems. Natural abundances of stable nitrogen isotopes (delta N-15) were measured in oyster (Crassostrea virginica) tissues (muscle, gills, and mantle) during summer 2006 to summer 2008 to identify nitrogen sources in Monie Bay (a subestuary of Chesapeake Bay) receiving freshwater inputs from three tributary creeks. The creeks (estimated flushing times:

Ecosystem-based management is widely regarded as a method to improve the way we manage our coastal marine resources and ecosystems. Effective ecosystem-based management relies upon synthesizing our scientific knowledge and transferring this knowledge into management actions. Integrated ecosystem assessment is a framework to conduct this scientific synthesis and transfer information to resource managers.

The America's Watershed Initiative Report Card project began with a regional workshop for the Upper Mississippi River Sub-Basin, held in Moline, Illinois on September 11–12, 2013. At the workshop, stakeholders and experts from social, economic, and environmental sectors identified easily understood and transparent ways to measure status and trends for the Upper Mississippi River Sub-Basin in relation to six broad goals.
