Project Description:
(Up to 250 words)
Over the length of the project, the San Francisco Bay National Wildlife Refuge Complex will be developing a much more intensive Integrated Pest Management Plan and weed management program. A new Wildlife Refuge Specialist position has been established to address weed management issues for the Complex and to initiate a volunteer program to help answer questions that need to be addressed in order to develop weed management goals and objectives, specifically; what species are present, what species are new to the area, where these species are, are and where they are not. We will be working with our Volunteer Coordinator, and our Native Plant Nursery Manager (who is a volunteer) to create a volunteer base that will help address the aforementioned questions by monitoring disturbed areas along roads and trails for Early Detection and Rapid Response treatment of newly detected species, mapping already established weed infestations, hand pulling shallow-rooted invasive weeds, and monitoring the success of manually and chemically treated weed areas.

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
In September of 2010 we initiated a volunteer group called the Weed Wranglers, in which volunteers controlled invasive weed infestations and restored habitat through direct weed management (i.e., cutting, digging or hand pulling weeds). Currently, we are working with our Visitor Services department to initiate an “Adopt a Trail” program in which volunteers will choose an existing trail on the Refuge, and monitor the trail seasonally for pre-determined weeds. Refuge staff will train volunteers to identify plants and how to navigate GPS technology. Volunteers will map weed infestations or new sightings of species, work with Refuge Staff to verify these sightings, and upload data into the Weed Database for map making purposes.
Total Number of Volunteers: 6
Total Number of Volunteer Hours: 180
List both new and existing partnerships utilized in this project. (Up to 150 words).
The Refuge Biology Department is partnering with the Refuge Visitor Services Department to develop the "Adopt a Trail" program. Partnerships like this go a long way in fostering camaraderie between departments and personnel, at a large Refuge Complex where they often work in isolation from, and feel overlooked by, other departments and staff.


Project Results:
Give an overview of the results of the project. Include quantifiable measure of success, such as maps produced, efficacy of control measures, number of sites where invasions were detected early and responded to, number of community contacts, etc. (Up to 250 words).
Using clippers, loppers, shovels and hand pulling the "Weed Wranglers" volunteers in 2010, were able to remove approximately 80 60-gallon bags full of Dittrichia graveolens, one of the most invasive species on the Refuge. We anticipate at least ten times the amount of effort in 2011. The “Adopt a Trail” volunteers will monitor and map the most invasive weeds on trails of the Refuge, which will enable Refuge biologists to more effectively track and control new weed populations of known weeds, and keep a look out for the introduction of new weed species. Volunteers will help Refuge Staff to create weed maps which will be used to track population trends amongst years.
Number of Acres Treated: 10 in year 2010. We anticipate treating at least 50 acres in 2011.
Number of Acres Inventoried and/or Mapped: We anticipate monitoring and mapping at least 5 miles of roads and trails in 2011.
Number of Acres Restored: We are not restoring treated acres with this volunteer program. However! a separate Refuge volunteer program re-vegetated several of the sites where we pulled weeds in 2010.


Budget: Account for funds in broad categories such as equipment, volunteer stipends, travel, coordinator salary/contract, etc.
