Project Description:
(Up to 250 words)
This project is at the southernmost edge of the San Francisco Bay, on a 12 acre artificial upland fill peninsula adjacent to Artesian Slough, in Alviso, CA. The peninsula was 98% covered in non-native invasive plants such as mustard, poison hemlock, thistle, stinkweed, and pepperweed. Refuge volunteers and staff have been eradicating the weeds using a variety of techniques such as herbiciding, mowing, and hand pulling. Over the years we have reduced the density of invasive plants but have not been able to transition to native plants. In 2007 Peter R. Baye, Ph.D., in partnership with the Refuge, completed a Vegetation Management Plan (Plan) which incorporates weed management and restoration of the site with alkali grasslands, vernal pool, riparian scrub and valley oak woodland species. This year we began to experiment with Dr. Bayes recommended techniques to eradicate invasive plants as outlined in the Plan, such as salinization (salt water irrigation), solarization (use of plastic to kill invasive plants), and the use of cover crops. These various techniques exclude the invasives in favor of native plants. This year the salinization test plots had a 95% reduction of invasive plants. As a result, this fall we plan to expand the invasive control area beyond experimental sites and restore native plant species to the area, thereby creating a sustainable native plant community. In order to achieve this we need additional tools and supplies, such as salt water irrigation equipment, cover crop seeds, planting equipment, erosion matting, mower, weed whacker, and backpack sprayers. We expect that these techniques will be transferable to other Refuge units in the future.

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
Every Tuesday a core group of 2 - 6 Refuge Volunteers meets to work on the project. In addition we have a partnership with HOPE services (see below for a description), community service days with the Children Discovery Museum of San Jose, CISCO systems, and the general public on Saturdays. The volunteer hours and number of volunteers reflected below are from July 1 - October 15- since the project is not complete these numbers will increase in the next report.
Total Number of Volunteers: 135
Total Number of Volunteer Hours: 551
Partnerships:
List both new and existing partnerships utilized in this project. (Up to 150 words).
We have a partnership with HOPE services, an organization that helps people with disabilities find jobs. A group of 7 workers from HOPE and 1 supervisor comes out 2 - 4 times a month. The workers from HOPE are paid for their time with funding from HOPE. The HOPE group has helped us reduce the number of invasive plants in the revegetation site significantly.


PROJECT RESULTS

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).
So far we have mapped the weed zones using our GPS/ GIS systems (all 12 acres). In addition, we have been hand pulling and spraying weeds with herbicide. Since the project is not yet complete - I will be reporting more information in December about salinization and cover crop techniques we will be implementing this fall. This year, we have erradicated 90% of our invasive plants before they went to seed (early detection) however since it has not rained yet - it remains to be determined how many will begin to grow again.
Number of Acres Treated: 12 acres
Number of Acres Inventoried and/or Mapped: 12 acres
Number of Acres Restored:

Recommendations: (OPTIONAL)
How useful was this program for meeting refuge invasive species objectives and how can it be improved?
Recommendations:This grant is extremely useful in helping us meet our objectives. The way it can be improved is to allow more time to spend the money and report back - ex: 1 full year - we would be able to get through an entire weed/ growing season and then be able to report back afterwards. By the time I knew we had the money this year it was really late and I have to report back before an entire growing season which is difficult. Thank you for this opportunity.
