Total Number of Acres Mapped (since project initiation): 515 acres of mapped invasives, ~6000 acres inventoried for invasives
Have You Shared Mapping Data with USGS in Ft. Collins? Yes

Describe Projects Initiated with Follow-Up Funds ($10,000): Continued mapping of invasive species on Refuge, with about 2/3 of the area inventoried to date. Treatment of approximately 200 additional acres that would otherwise be untreated. Evaluation of best treatment methods for control of flowering rush. Funding for seasonal invasive species coordinator for mapping and control of invasives, and providing WIMS training and advice to personnel at other Refuges.
Total Number of Acres Treated with Follow-up Funding: 200
Total Number of Acres Restored with Follow-up Funding: 50
Total Number of Volunteers Engaged in Treatment and/or Restoration: 3


How has this Project Benefited Invasive Species Management Efforts at Your Station? This project has provided numerous benefits to the Refuge. Mapping allows us to more efficiently prioritize treatment efforts, evaluate the effectiveness of treatments, and monitor for expanding populations. It aids us in identifying new outlying populations early after establishment, so that we can rapidly respond and eliminate the problem species. We have been able to do some experimental treatments to determine the best management and control options, especially for flowering rush and giant reed. For example, this year we experimented with a combination of pesticide application methods (backpack, boom spraying) and mechanical treatment (disking) to evaluate best control methods for flowering rush. Funding for a seasonal invasive species coordinator more than doubles the amount of mapping and treatment the Refuge is able to accomplish.
What are some of the Lessons Learned and/or Troubleshooting Points that could be Shared with Others Engaged in Similar Activity?
Mapping databases push the limits of current PDA technology, and patience is necessary especially if using aerial photography with the PDA. Systems failures sometimes occur for no known reason on the PDAs and require system resets or sometimes full reinstallation. Make sure you regularly back up the desktop database, and keep backup copies of data used on the PDAs.
