Which, if any, of these Species are Early Detection Species: Arundo donax
Total Number of Acres Mapped (since project initiation): Area surveyed = 1,398ac., gross Lepidium mapped = 188ac., infested = 30ac.
Have You Shared Mapping Data with USGS in Ft. Collins? Yes

Describe Projects Initiated with Follow-Up Funds ($10,000): Expanded training and mapping efforts to Marin Islands NWR and Antioch Dunes NWR. Received additional grants (total=$50K) to develop a Lepidium control plan, apply treatments, develop community based education related to invasive plants, and propagate and outplant natives in treated areas. Our first treatments will occur in summer 2006. The control plan will guide treatment activities in 2006.
Total Number of Acres Treated with Follow-up Funding: 0-treatment begins summer 2006
Total Number of Acres Restored with Follow-up Funding: 0-restoration begins fall 2006
Total Number of Volunteers Engaged in Treatment and/or Restoration: 0-anticipated in 2006 = >50


How has this Project Benefited Invasive Species Management Efforts at Your Station? The San Pablo Refuge did not have an invasives program prior to 2004. The introduction of WIMS and engagement of volunteers allowed the Refuge to begin mapping invasive perennial pepperweed in tidal marshlands of the Refuge and adjoining lands. Our efforts have ignited interest and enthusiasm from our volunteers and our partners. Our efforts have led to additional funding from NFWF, the USFWS Coastal program, and in-kind resources from our partners and neighbors to address invasive issues on the Refuge (and on adjacent lands), expand education, and expand community participation in restoration. Lastly, the exported shapefiles provide a great tool for examining the extent/pattern of invasives relative to other environmnetal features and will assist in the development of a control program.
What are some of the Lessons Learned and/or Troubleshooting Points that could be Shared with Others Engaged in Similar Activity?
Be patient in starting your program. It takes time to develop a solid team of volunteers and to become fluent with the WIMS database. Ask questions...don't be afraid to ask others for help concerning WIMS issues. Use the WIMS message board to browse previous technical issues or to post new questions (http://ice.ucdavis.edu/wims/index.php).
