Which, if any, of these Species are Early Detection Species: Houndstongue,Leafy Spurge,Dalmation Toadflax,Diffuse knapweed
Total Number of Acres Mapped (since project initiation): ~250
Have You Shared Mapping Data with USGS in Ft. Collins? No

Describe Projects Initiated with Follow-Up Funds ($10,000): Hired a seasonal bio-tech to help with training volunteers, quality control of data management, and mapping priorities. Additionally we used the GPS unit and historic information on weed location to check on success of past years control efforts
Total Number of Acres Treated with Follow-up Funding: ~200
Total Number of Acres Restored with Follow-up Funding: 0
Total Number of Volunteers Engaged in Treatment and/or Restoration: 3


How has this Project Benefited Invasive Species Management Efforts at Your Station? Having this project has given new and former volunteers the opportunity to learn new skills, and apply these to the things they enjoy in the outdoors. It has given the station the opportunity to collect new baseline data on weed distributation above the usual target species. With that information the refuge staff can better utilize the limited resources of staff time and equipment to eradicate weeds.
What are some of the Lessons Learned and/or Troubleshooting Points that could be Shared with Others Engaged in Similar Activity?
In the training, it is important to teach the volunteers how to estimate plant cover percentages (i.e., what percent of the ground is covered by what) in a standard manner.
