Introduction: Blackwater National Wildlife Refuge has lost 8,000 acres of marsh since the 1930s from a number of causes, including excess herbivory by nutria. The reduction of nutria from Blackwater has made wetland restoration feasible. On-site dredged material was used to create and restore approximately 27 acres of wetlands in 1980-1984 and 2003. The success of these efforts has shown that the marsh can be restored and maintained over time. Blackwater Refuge and partners (U.S. Geological Survey, National Oceanic and Atmospheric Administration, MD Department of Natural Resources, Port of Baltimore, National Aquarium in Baltimore, Army Corps of Engineers, and Friends of Blackwater) would like to continue restoration efforts on a larger scale. However, Phragmites australis, which is established throughout the interior marshes of Blackwater Refuge, is beginning to invade these restored wetlands. Management of this invasive is essential to the continued success of these restored acres, and future restoration efforts. Objectives: " Eradicate Phragmites present within the restored wetlands. " Implement an annual Phragmites management program within the interior natural marshes to prevent spread into restored areas, and eventually eradicate Phragmites.

Describe the type of work the volunteers performed. (Up to 150 words)
Refuge volunteers inventoried Phragmites using a Global Position System (GPS) unit and the Weed Information Management System software. Volunteers who were not comfortable using the GPS, drew Phragmites infestations onto paper maps to be compared with vegetation map and digitized if need be. " Refuge volunteers hand pulled and chemically spot treated Phragmites within restored wetlands. " Refuge volunteers took photos of phragmites stands before treatments at established permanent monitoring points. " Refuge volunteers assisted with chemical management of Phragmites within impoundments and the interior marshes that surround the restored wetlands.

List both new and existing partnerships utilized in this project. (Up to 150 words).
Give an overview of the results of the project. Include quantifiable measure of success, such as maps produced, efficacy of control measures, number of sites where invasions were detected early and responded to, number of community contacts, etc. (Up to 250 words).
Volunteers treated Phragmites with a mixture of herbicides Habitat and Glypro. Spray tanks mounted on refuge trucks, Argo, and marshmaster were used. Backpack sprayers were also used from boats in water accessible only areas. The marshmaster and trucks with high pressure and 100' long hose was most effective. Wetland restoration areas were targeted as management priorites, and then volunteers and staff moved onto managed wetlands (impoundments) and surrounding natural marshes. Volunteers mapped 375 acres of treated Phragmites using GPS units and GIS. Maps were created. Volunteers also assisted with photo monitoring points established in marshes.
