Introduction: Barren Island is one of seven islands administered by the Chesapeake Island Refuges, and is one of only a few uninhabited islands remaining in the Chesapeake Bay. Erosion, wave action, land subsidence and sea level rise are causing Barren and similar island habitats to disappear. The U.S. Fish and Wildlife Service, the National Aquarium in Baltimore, National Oceanic and Atmospheric Administration Restoration Center, Friends of Blackwater NWR and many other partners have been using clean dredged material to create and restore wetlands on Barren Island, providing habitat and protecting the island from further erosion. Community volunteers and local students are recruited to help plant and monitor the restored wetland. Since 2001, over 700 volunteers have helped install 231,500 plants and monitor the 17.5-acre restored wetland. The results of these restorations have shown reduced erosion, extensive animal habitat utilization, and high levels of plant survival and growth. However, Phragmites australis, which is established throughout the interior marshes of Barren Island, is beginning to invade these restored wetlands. Management of this invasive species is essential to ensure the continued success of these and future wetland restoration acres. Objectives: " Eradicate Phragmites present within the restored wetlands. " Implement an annual Phragmites management program within the interior natural marshes of Barren Island to prevent its spread into restored areas, and eventually eradicate Phragmites. Methods: " Refuge volunteers will inventory Phragmites using a Global Position System (GPS) unit and the Weed Information Management System software. Data will be downloaded and managed in a Geographical Information System (GIS). " Refuge volunteers and staff will hand pull and chemically spot treat Phragmites within restored wetlands. " Refuge volunteers will establish photo monitoring points within treated areas to determine success of treatments. " Refuge volunteers and staff will mechanically and chemically manage Phragmites within the interior marshes that surround the restored wetlands. " Refuge volunteers will establish photo monitoring points within managed areas to determine success of treatments.

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 the interior marshes that surround the restored wetlands.

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 assisted in treating approxmately 5 acres of Phragmites on Barren Island. Phragmites was treated with a mixture of herbicides Habitat and Glypro. Volunteers spot treated Phragmites with backpack sprayers in the wetland restoration areas. Pulling of young Phragmites shoots was not effecient. Stems broke off and they were hard to pull. Unfortunately, Phragmites is encroaching at full speed into the restoration area. Approximately, 15% - 20% of the area was invaded by Phragmites. There was concern of killing newly planted grasses. Care was taken to only target Phragmites. Treatment of the surrounding marshes was conducted using an Argo with a spray tank mounted on the back. This did not go as smoothly as expected. Recommend using Marshmaster since it is less likely to get stuck in the marsh. Volunteers also took monitoring photos and noted that there was over 50% control of the Phragmites from 2005 treatment. Volunteers mapped Phragmites using GPS units and in GIS. A map was created. We will not know percent control for 2006 treatments until spring of 2007. *extra chemicals will be used for follow up treatments.
