How has this Project Benefited Invasive Species Management Efforts at Your Station? We almost have a baseline map of the invasives distribution in two of our units. We will be ready to develop a Weed Management Plan for one of the units based on the mapping since 2003. Mapping of the roads in 2004 demonstrated their importance as vectors to plant invasion.
What are some of the Lessons Learned and/or Troubleshooting Points that could be Shared with Others Engaged in Similar Activity?
This program requires that a staff member is involved weekly. Our volunteers had some problems inputting all of the information into WIMS. Weekly data checking should limit this problem. The volunteers are eager to walk around areas of the refuge that are usually closed, and to contribute to the management of the refuge. Most of the volunteers aren't technically savy, encourage your volunteers to explore the functions of the GPS units before they go into the field.
