How has this Project Benefited Invasive Species Management Efforts at Your Station? We would not have any weed mapping of the Refuge without this program. We use this data to plan control efforts and chemical treatments. For the past two years we have used the Montana Conservation Corps High School group to map and treat tansy ragwort. They search an area and map using gps any plants found. They then clip and bag the seed heads, and spray the remaining plant. The crew consists of 6 to 8 local youth and two crew leaders. Both years that the Montana Conservation Crew came to the Refuge, the voted this their most valuable project of the summer. These local teens learn about weeds, and weed control. We teach them about bio-control as well as chemical treatement and why weeds are such a problem. I believe that most of these youth will not be able to pass by a tansy ragwort plant without pulling it. Last year the crew found a bio-control agent on one site of tansy ragwort. This agent had been released on forest service lands near the refuge but this was the 1st time it was found on the Refuge. We also located another location of the endangered plant, Spalding's Catchfly on the Refuge. If this group hadn't weed mapped in this area we would not have know about this location.
What are some of the Lessons Learned and/or Troubleshooting Points that could be Shared with Others Engaged in Similar Activity?
