Locate and map, via the use of GPS, Rush skeletonweed on the refuge. Located areas then entered into GIS to allow refuge staff to pin point locations and treat this invbasive species.

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).
Approximately 8100 acres of the total 9959 acres of the refuge were searched for Rush skeletonweed during this project. Of the 8100 acres, 2245.79 acres were categorized as having dense stands of Rush skeletonweed. Maps were developed to identify large areas of skeletonweed, as well as points to identify smaller more isolated areas to improve the ability of staff to locate these areas for treatments. The dense areas were localized to 3 core areas.
Number of Acres Treated: approximately 1000 acres
Number of Acres Inventoried and/or Mapped: 8099.04
Number of Acres Restored: 0


Budget: Account for funds in broad categories such as equipment, volunteer stipends, travel, coordinator salary/contract, etc.

Recommendations: (OPTIONAL)
How useful was this program for meeting refuge invasive species objectives and how can it be improved?
The program was very successful in identifying areas to focus needed treatments with regards to Rush skeletonweed. However, additional funds would be needed to allow individuals to focus their attentions on certain species, as refuge staff were responsible for treating various other invasive species on the entire refuge, and could not take the time necessary to focus strictly on one species. A crew would be needed to focus solely on Rush to allow for any realistic hope of full erradication.
