How has this Project Benefited Invasive Species Management Efforts at Your Station? This project has helped give the refuge a tool to begin the process of tracking the spread of invasive species on U.S. Fish and Wildlife Service lands. It has also provided a foundation and direction for prioritization of future treatments of infestations especially when it comes to early detection and eradication.
What are some of the Lessons Learned and/or Troubleshooting Points that could be Shared with Others Engaged in Similar Activity?
We were originally trained in WIMS. However, Region 2 choice of database was RLGIS. So mapping was mostly done in points with Garmin units and transferred to ArcGIS 9 as a shape file. This information is in the process of being transferred to RLGIS. The lesson learned from a data management stand point would be to have information gathered with a hand held device like a PDA or Trimble to cut down on transcription errors and make work more time efficient.
