ADDITIONAL INFORMATION

How has this Project Benefited Invasive Species Management Efforts at Your Station? The Volunteer Invasives Mapping Project has allowed San Pablo Bay NWR to develop and implement a program focused on control of invasive plant species and restoration of native plant assemblages. The program has also expanded to Marin Islands NWR. Much of the annual follow-up funds (e.g., 10K) have been used to build the infrastructure for our mapping program (e.g., GPS units, kayaks, field supplies) and to hire interns for mapping and related restoration. The initial training, base funds, and subsequent mapping efforts have provided significant leverage for obtaining additional grants to fund large-scale treatment, native plant propagation and planting (restoration), and education. We have built several new partnerships as a result of this program: The Bay Institute, Save the San Francisco Bay Assoc., Sonoma Land Trust, CA Dept. of Fish and Game, Marin-Sonoma Weed Mgt. Area. As a result of our success in 2006, The Bay Institute is now raising funds so they can continue working with the Refuge in 2007 and assist with Refuge treatment and propagation funding. In 2006 we established the San Pablo Bay Native Plant Nursery and successfully propagated and planted over 3,300 plants. Our hope is that these species will act as a source from which natives can spread throughout the Refuge. Large-scale treatment of Lepidium latifolium will take place at San Pablo Bay NWR in May 2007. This is the first well-documented project focused on control of this species in a tidal marsh environment.
What are some of the Lessons Learned and/or Troubleshooting Points that could be Shared with Others Engaged in Similar Activity?
Be patient with technology, monitor your efforts, find/make new partners, join your local weed mgt. area if you have one, treat your volunteers really well, leverage your volunteers as in-kind $ to raise additional funds for control/restoration.
