List of Invasives Species Mapped:Common NameScientific Name
  kudzu Pueraria lobata
privet Ligustrum vulgare
bamboo Bambusa spp.
mimosa Albizia julibrissin
Which, if any, of these Species are Early Detection Species: EDRR is being applied to Privet; the kudzu and bamboo have been established and known for better than a decade.
Total Number of Acres Mapped (since project initiation): 190
Have You Shared Mapping Data with USGS in Ft. Collins? Yes

Describe Projects Initiated with Follow-Up Funds ($10,000): Since 2005 Cache River has mapped several infestations and used follow up money to purchase herbicides, spray equipment, and PPE for volunteers. Volunteers spent several weeks on treatment efforts.
Total Number of Acres Treated with Follow-up Funding: 40
Total Number of Acres Restored with Follow-up Funding: 0
Total Number of Volunteers Engaged in Treatment and/or Restoration: 2


How has this Project Benefited Invasive Species Management Efforts at Your Station? By enabling the Refuge Staff and volunteers to begin mapping invasives this program has literally opened our eyes to see how big of an impact invasives really have on the habitat. Follow up funds have been extremely helpful to not only continue mapping, but especially treat areas and stay ahead of new infestations. Invasive control is now a part of our summer routine and funding, such as this, has become crucial to help us maintain and improve wildlife habitat and meet our objectives.
What are some of the Lessons Learned and/or Troubleshooting Points that could be Shared with Others Engaged in Similar Activity?
Kudzu control involves a multi year commitment - we have implemented chemical control for 3 years, and now we are down to only spot control - we have seen good improvement. Privet is easier to control; however, you must be on the look out for new seedlings advancing in to any location where there is sunlight. Stay up with your mapping and treatments; it pays off in the long run for planning, adaptive management, and reporting.
