Communication among managers, the public, and scientists is the key to successful ecosystem management; however, the varied perspectives and interests of these groups can make such communication difficult. One way to achieve effective communication is to develop a common knowledge base by combining syntheses of key scientific results with information-rich visual elements.

Seagrasses, marine flowering plants, are widely distributed along temperate and tropical coastlines of the world. Seagrasses have key ecological roles in coastal ecosystems and can form extensive meadows supporting high biodiversity. The global species diversity of seagrasses is low (b60 species), but species can have ranges that extend for thousands of kilometers of coastline.

The mid-Atlantic coastal bays are shallow coastal lagoons, separated from the Atlantic Ocean by barrier sand islands with oceanic exchanges restricted to narrow inlets. The relatively poor flushing of these lagoon systems makes them susceptible to eutrophication resulting from anthropogenic nutrient loadings. An intensive water quality and seagrass monitoring program was initiated to track ecological changes in the Maryland and Virginia coastal bays.

South-west Australia contains extensive seagrass meadows along 2,500 km of coastline from the shallow subtidal to 50+ m water depths, and in many of the 51 bar-built estuaries along the coast. There are geomorphological differences between the south and west coasts that result in different patterns of swell exposure influencing the processes that structure seagrass habitats.

SINCE ITS INCEPTION, the National Park Service (NPS) has been charged with preserving the natural and cultural heritage of the United States for future generations. It is only recently, however, that the NPS has fully embraced the need to understand and describe the ecology of parks. The infusion of an ecological perspective into the natural resource management of the national parks is what separates today's park management from much of that which preceded it (Sellars 1997).

This poster series outlines the work of the National Capital Region Network's (NCRN) Inventory and Monitoring Program. The program's role is to monitor the status and trends of the parks, their vital signs and development pressures. Park vital signs monitoring is designed to inform managers of the condition of water, air, plants and animals, and the various ecological, biological, and physical processes that act on those resources.

Antietam National Battlefield is managed within the historical context of General Robert E. Lee's first invasion of the North during the Civil War. The 1,926 acre park is located in the heart of Maryland and is surrounded by rolling hills dotted with farm fields and pastures reminiscent of the day of battle. Patches of forest, open meadow, streams, and cropland are found within the park.

Catoctin Mountain Park originated as a Recreation Demonstration Area in 1936 and is managed today for its recreational use and the conservation of its cultural and natural resources. The park encompasses 5,810 acres of mixed hardwood forest located in the mountains of the Catoctin Ridge in north-central Maryland. Two high-quality streams bisect the park and the unique three million year old geology forms a number of cliffs and scenic vistas.

The Chesapeake & Ohio Canal National Historical Park is the largest and longest park in the National Capital Region, stretching along the Potomac River for 184.5 miles from Washington, DC to Cumberland, MD. The park's 19,236 acres cut through four major physiographic provinces and include diverse wetlands, floodplain, and upland forests. Hundreds of historic structures are preserved as reminders of the Canal's role as a major transportation system during the Canal Era.

George Washington Memorial Parkway was established to protect the scenic views along the Potomac River and its tributaries in the Washington, DC area. The park's 7,210 acres provide habitat for dozens of state-listed species of rare, threatened, or endangered plants and animals, many of which are associated with rare plant communities of the Potomac River Gorge.
