Project Description:
(Up to 250 words)
Treatment and removal of invasive plant speices at Wallkill River and Shawangunk Grasslands. Some invasives are well established (barberry,buckthorn,phragmites)and more difficult to control but others, such as water chestnut were caught early and have been controlled and almost eliminated. This will be accomplished by manual and chemical means, such as cutting and stump apraying and general broadcast spraying of other areas. This part of the project will be supervised by the staff licensed pesticide applicator. Specific areas to be addressed are improvement of habitat for grassland nesting birds, removal of invasives along existing public trails in an attempt to limit spreading in these corridors and removal in new trail corridors before opening them to the public. As important as public use is, it does create a vehicle for the unintentional spread of invasive seeds. The second part of the project is to map areas of invasives using GPS and GIS technology, thus allowing us to track actions that have been taken and prioritize future actions to be taken.

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
Our friends group volunteer invasives coordinator recruited a labor force to manually remove invasives along existing public trail corridors. Prior to startup, an educational walk was scheduled to orient volunteers and the public to the problem of invasive plants. Erradicaton was also undertaken along newly proposed public trails prior to opening them to the public. Summer interns mapped acreage on land and water and assissted in the manual removal and chemical treatment part of the project. A small restoration project was initiated at the end of the season. Native trees and shrubs were purchased and a work day was scheduled. In addition to the trees and shrubs purchased, the first group of trees and shrubs grown on site were added to this restoration project. This was the result of a previous (FY2009) CCS grant to establish an on site greenhouse and nursery to grow native plants from our on site natural seed bank.

List both new and existing partnerships utilized in this project. (Up to 150 words).
The existing partnership with our Friends group was heavily utilized to do a significant amount of manual labor and public outreach. They also established a new partnership with the environmental club at Sussex County Community College who participated in the trail work project. The Sussex County Sheriff's Labor Assisstance Program was also utilized to do invasives removal along the newly proposed trail corridor. The mapping effort was accomplished by the summer interns who also participated in the manual removal and stump spraying aspects of the project. The restoration project was done by the Hardyston Cub Scout Pack #298.


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).
Efforts to control water chestnut have been very successful. After finding a widespread outbreak in 2008, we have aggressively attacked this invasive and have nearly eliminated it. The effort to remove invasives on the new trail section were very successful as this was accomplihed before opening to the public. Control along existing trails is more problemtic but this project has given us a focus and new partnerships which should allow us to control and restore additional areas. The extensive GIS mapping initiative gives us a tool to prioritize and respond to problem areas as resources permit. While it is almost impossible to control all invasives, these tools help us to selectively target areas of concern.
