The Humboldt Bay National Wildlife Refuge has been developing a volunteer-based invasive weed mapping and control program since 2003. Approximately 800 acres and 35 miles of roadsides were surveyed for 24 invasive weeds. Volunteers spent 1000 hours on mapping and control efforts and on invasives management education. Community support for invasives removal is essential for the long-term success of any control effort. There are several components that need to be added to our program to develop a volunteer-base that is committed to the continuation of invasives control at the Refuge. First we need to increase the number of volunteers capable of surveying for invasive weeds and mapping their locations and treatments. Additionally, a segment of the Refuge support group needs to be educated in invasion biology management methods so that they can act as rapid response weed eradicators. In the 2006-2007 season with financial support from this grant the project will cover these three objectives: educate long-term volunteers to work with staff members to recruit and train new volunteers, develop an annual community weedpull to focus on the removal of incipient populations of highly invasive weeds, and continue surveying and mapping Refuge subunits .

Describe the type of work the volunteers performed. (Up to 150 words)
The newly formed Refuge support group, Friends of Humboldt Bay NWR has taken an active role in the invasives mapping portion of the project. Several members participated in a WIMS training and are currently mapping sections of the Hookton Slough Unit, HBNWR. Volunteers participated in the first annual rapid response weed removal event. An incipient population of barnyard grass, (Echinochloa crus-galli) was almost completely removed. Volunteer coordination by the Friends group is continuing to remove the rest of the occurrence.

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).
A core-group of volunteers was trained in the WIMS/ArcPad mapping technologies. These volunteers will be available to survey for invasives in future seasons and will participate in the training of newly recruited volunteers. Members of the Friends of Humboldt Bay have participated in the mapping efforts and in the annual weed control event. The first annual community weedpulling event was held on September 24th. The only occurring population of invasive barnyard grass on the refuge was almost completely removed. Followup treatment is necessary because the species has a seed bank of more than 2 years. The annual rapid response event will be held in the springtime. This year it was held in the fall because of the contractor's availability and experience organizing similar events. The 2nd annual event will be in spring 2007. Fortuna high school students and their biology instructor participated in the weed removal event. They plan to participate in more events at the refuge. The refuge is developing a list of people who would like to participate as a rapid response team. They would be called if an incipient population of an invasive weed was found at the refuge.
Number of Acres Treated:
Two acres of barnyard grass infested area.
Number of Acres Inventoried and/or Mapped:
50 acres survey for 24 invasive weeds
Number of Acres Restored:

How useful was this program for meeting refuge invasive species objectives and how can it be improved?
The program allowed the refuge to train volunteers to survey for invasive species. These volunteers will continue the program in the years to come. This program is vital to refuge. It allows us to educate the public on the threat of invasive species and allows the public to participate in management activities at the refuge.
