The project consists of Refuge staff working with volunteers to map both target and Early Detection and Rapid Response (EDRR) invasive plant species on Ottawa National Wildlife Refuge. 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.

Describe the type of work the volunteers performed. (Up to 150 words)
The main involvement of volunteers is to inventory and map both target and EDRR invasive plant species on Ottawa National Wildlife Refuge. Volunteers 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. Volunteers are then given designated areas within the Refuge to inventory. When an invasive species is discovered, the volunteers then map the invasive. The volunteers then record all required descriptive information such as species, growth stage, and density. Selected volunteers are trained in pesticide application and assist refuge staff in treatment of invasive plants.

The project funds were allocated for the continuation of the Volunteers Working with Invasive project on Ottawa National Wildlife Refuge. For the 2008 field season a total of roughly 750 acres of critical habitat were inventoried. EDRR efforts focused on invasive pathways such as dikes and waterways, and on areas within the Refuge that are relatively undisturbed by invasive plants. During 2008, nearly all potential invasive pathways were inventoried, with immediate follow up treatment when EDRR species were detected. Three new EDRR species were discovered in 2008 on Ottawa NWR (Iris pseudacorus, Carduus nutans, and Berberis thunbergii). During 2008, a total of 25 new populations of EDRR species were mapped and treated throughout the Refuge. During the 2008 field season within the Crane Creek Eastern prairie fringed orchid restoration site, an additional 32 acres of key habitat were inventoried for invasive species. In 2008 an EDRR field guide was developed for Ottawa NWR and its use made mandatory by all field volunteers, researchers, and staff. The guide was also available for volunteers, educational groups, and the general public. A ‘weed of the week’ handout series was designed and then displayed within the visitor center and at various kiosks throughout the Refuge. Each handout depicts information regarding a specific invasive plant. Two workshops titled Get to Know Your Local Invasives were held at Ottawa NWR. Due to these efforts, the public is more conscious and aware of the impacts of invasive species on native habitat.
Number of Acres Treated:
A total of 630 acres were treated in 2008.
Number of Acres Inventoried and/or Mapped:
Roughly 750 acres were inventoried in 2008.
Number of Acres Restored:
Roughly 200 acres restored, however restoration is still in progress.
Account for funds in broad categories such as equipment, volunteer stipends, travel, coordinator salary/contract, etc.

How useful was this program for meeting refuge invasive species objectives and how can it be improved?
The project is most benifical in the assistance of acheiving Ottawa NWR goals for mapping, monitoring, and treatment of invasive species. More effort should be placed on recruiting potential volunteers for the project.
