Five acres of refuge property adjacent to the site of the new refuge headquarters and visitor contact station are targeted for habitat restoration through this project. Students and other volunteers manually cut two acres of Japanese knotweed during the summer of 2005. After allowing the knotweed to regrow, adult volunteers chemically treated the regrowth as well as an additional acre of Japanese hops and reed canary grass. Follow-up spraying to control any remaining Japanese knotweed will take place in Spring 2006. Volunteers will use a combination of herbicide control and mowing on the remaining acreage in 2006, and the entire five acres will be planted with native trees and shrubs (raised by volunteers)in Spring 2007 to restore the native bottomland hardwood forest.

Describe the type of work the volunteers performed. (Up to 150 words)
Volunteers manually cut two acres of Japanese knotweed and did a follow-up herbicide treatment of the regrowth. They also applied herbicide to an additional acre of Japanese hops and reed canary grass and began treatment of tree of heaven using the "hack and squirt" technique.

Students and staff from Fairplains Elementary School visited the project site on two occasions. The first trip focused on learning about invasives plants, including identfication skills. The follow-up trip was devoted to cutting Japanese knotweed. A local Boy Scout troop and members of the Marietta Natural History society participated during a "knotweed knock-out" party. Additionally, a Marietta College student is working with the refuge to evaluate the control measures used on this project.
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).
While evaluation of the success of this project will not be determined until reforestation efforts are completed in Spring 2007, initial invasive response to treatments on three acres appearslargely successful with a strong decline in the vigor of the Japanese knotweed clones. However, control of the knotweed allowed Japanese hops to exploit the site and required additional treatment. We modified our control strategy plans to include future mowing in areas of the site where annual invasives such as mile-a-minute are expected to be a problem.

How useful was this program for meeting refuge invasive species objectives and how can it be improved?
Without this program, we would have been unable to implement this project. It will help us to evaluate invasive plant control strategies that we can apply to many additional refuge acres. It also helps us interpret invasive species problems and control strategies to our publics.
