Project Description:
(Up to 250 words)
Tennessee NWR is a major wintering area for waterfowl in the Mississippi Flyway and provides for the needs of many other species of waterbirds, including rails, shorebirds, and herons within diverse wetland habitats. Invasive exotic plants are degrading some of the aquatic habitats to a point that they are no longer desirable to many migratory birds. Parrotfeather and purple loosestrife are currently only known to be located within a few small areas on the refuge. A comprehensive inventory of the wetland habitats in the vicinity of the known communities is needed to fully document the impact of these two plant species. GPS and GIS technology will be used to mark and map all locations. Control measures will then be employed to control all documented areas of parrot feather and purple loosestrife. Parrotfeather will be treated with herbicide (Habitat) by aerial treating the larger infestations and spot treating small patches using ground methods. Biological control will be used on the purple loosestrife by releasing Galerucella beetles at infested sites. Inventory efforts will be accomplished during early June and treatment will occur during June and July. Post-treatment monitoring will extend through October. Follow-up monitoring and treatment if needed will occur in 2006.

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
The volunteer on this project assisted with searches for parrotfeather and spot treated isolated patches with herbicide using a backpack sprayer. He released the Galerucella beetles on the known populations of purple loosestrife and searched for new populations.
Total Number of Volunteers: 1

Project Results:
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).
There were 42 acres adjacent to the known parrotfeather infestations that were inventoried. One previously undocumented population of about 0.25 acre was located and treated. GPS locations were acquired for all known infestations and entered into ArcGIS to produce a map. A total of 20 acres were founded to be infested with parrotfeather. All populations were chemically treated with Habitat herbicide, 15 acres aerially using a helicopter and 5 acres on the ground using ATV and backpack sprayers. Preliminary monitoring has revealed no resprouting, indicating good control. Monitoring of this treatment will continue this fall and into the 2006 growing season. Approximately 100 acres were searched on the Busseltown Unit for purple loosestrife. No new populations were found. Galerucella beetles were released on the only known population that occupies about 3 acres. No control has been observed at this time. Monitoring of this treatment will continue this fall and into the 2006 growing season.
Number of Acres Treated: 20
