Describe Projects Initiated with Follow-Up Funds ($10,000): Garlic mustard patches were first identified in 2005 when the entire 14,000 acre Refuge was mapped through a WIMS mapping project. These patches were relatively small and required immediate attention to keep small. Using these funds one intern was hired from North Dakota and two volunteer interns were recruited from Northern Minnesota and Central Louisiana to revisit twenty-four hundred acres of the Refuge. This area was the location of the greatest number of garlic mustard infestations. We found that the patches had grown in size to encompass approximately 80 acres. One third of these 80 acres were treated using chemical but more needs to be done. We will continue monitoring in FY09 and treat as funding and staff time provide. Seven Waterfowl Production Areas and one other Refuge Unit were mechanically treated with the help of the one Invasive Species Intern and two Volunteer Interns for Canada thistle. Over 200 acres were mowed and an additional 30 acres treated using a broad cast sprayer. These folks were critical to keep ahead of thistle seed production in FY08 and would not have been available to us if not for the additional funding. One Trimble Nomad was purchase with the additional mapping funding to assist in the mapping of invasive species on the Minnesota Valley NWR and WMD.
Total Number of Acres Treated with Follow-up Funding: 280
Total Number of Acres Restored with Follow-up Funding: 25
Total Number of Volunteers Engaged in Treatment and/or Restoration: 125


How has this Project Benefited Invasive Species Management Efforts at Your Station? Our Invasive Species Program is made whole through programs like this. In order to keep up with the continued demand that invasive species have on the refuge we need to continue to hire folks through funding sources such as this to assist in managing volunteer groups. It takes time lots of staff time to coordinate volunteers and by hiring an Invasive Species Assistant through funding sources like this we exponentially increase the number of volunteers working on Service owned and managed Lands.
What are some of the Lessons Learned and/or Troubleshooting Points that could be Shared with Others Engaged in Similar Activity?
Invasive species which can be considered in the "early detection stage" are treated in the early spring or late fall. We need to look for funding sources or take pieces of our annual budget to hire a seasonal employee who can assist during these critical times of the year or continue looking for volunteers who can work during these times. Most STEP students are either still in school or have gone back to school.
