Project Description:
(Up to 250 words)
The project consists of Refuge staff working with volunteers to map Early Detection and Rapid Response (EDRR) invasive plant species on Ottawa National Wildlife Refuge. Although volunteers mainly work with EDRR species, Refuge target invasive species are also mapped. Handheld mapping units (Recon TDS) are used to map invasive plants throughout the Refuge. Mapping units are equipped with GPS flashcards with WAAS capability. Each unit uses ESRI’s ArcPad 7.0 software for the mapping component with the Refuge Lands GIS (RLGIS) database for the collection of the field data. The RLGIS program is used for data collection, data analysis such as invasive plant distribution, producing reports used for management decisions, and generating GIS shape files. In 2008 the WIMS (Weed Inventory Management System) database that had been utilized for invasive collection since 2005 was replaced by the RLGIS database. Volunteers also assist with treatment and control of EDRR species.

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
The main involvement of volunteers is the inventory and mapping both EDRR and target invasive plant species on Ottawa National Wildlife Refuge. Volunteers also assist with the follow-up treatment of detected EDRR species. Before volunteers are sent into the field to map, they are trained in the following: plant identification (both invasive and native species found on Ottawa); basic knowledge of GPS and GIS; mapping methods and collection; operation of handheld mapping units; and understanding of ArcPad software and the RLGIS database. The volunteers are then given designated areas within the Refuge to inventory. Areas are surveyed by either vehicle, ATV, boat, or by foot. When an invasive species is discovered, the volunteers then map the invasive. When follow-up treatment is required volunteers are trained in equipment knowledge and usage. Select volunteers are trained in pesticide application and assist refuge staff in the chemical treatment of invasive plants.

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).
The project funds were allocated for the continuation of mapping and control of EDRR and target invasive species on Ottawa National Wildlife Refuge by both volunteers and staff. For the 2009 field season a total of roughly 2500 acres of habitat was inventoried. EDRR efforts focused on invasive pathways such as dikes, waterways, and new construction sites. Areas also included habitats that are relatively undisturbed by invasive plants. During 2009, nearly all potential invasive pathways were inventoried, with immediate follow-up treatment of EDRR species that were detected. Luckily only two new EDRR species were discovered in 2009 on Ottawa NWR (Centaurea maculosa, and Dipsacus fullonum). In addition, new populations of earlier detected EDRR species were mapped and treated. During 2009, a total of 13 EDRR species on 143 spots were mapped and treated throughout the Refuge. During the mapping project in 2007, the federally threatened Eastern prairie fringed orchid was discovered within the Crane Creek riparian restoration area. During the 2009 field season within the Crane Creek site, an additional 80 acres of key habitat were inventoried and treated for invasive species. In 2009, a total of 384 orchids were discovered. In 2009, 20 acres of critical beach ridge habitat was manually treated for spotted knapweed and tree-of-heaven (Centaurea maculosa, and Ailanthus altissima). A total of 100, 40-gal bags of spotted knapweed was hand pulled and removed. An EDRR field guide, developed by Ottawa NWR, which is made mandatory by all field volunteers, researchers, and staff.
Number of Acres Treated: 305 acres
Number of Acres Inventoried and/or Mapped: 2,500 acres
Number of Acres Restored: Restoration is still in progress.


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?
More effort should be placed on recruiting new potential volunteers for the project.
