This project analyzed existing aquatic sediments, plants, and animals collected throughout the watershed to pinpoint key sources of nitrogen. As submerged aquatic vegetation has disappeared in regions heavily impacted by land-use activities, macroalgae and oysters were deployed and incubated in situ to help trace the origin of nitrogen inputs by identifying, delineating and mapping the relative influence of the varied urban and agricultural land uses in the watershed.

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.

6 February 2014

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.
