Humboldt Bay NWR plays a unique role with its contribution to the protection of coastal dune and estuarine ecosystems. Its northern units represent some of the most pristine coastal dune ecosystems of the Pacific Coast of the United States. The southern units are an integral piece of the Pacific Flyway. Invasive species threaten the ecological health of these diverse ecosystems. The refuge volunteer invasives program has a four-year history of volunteer commitment. Between 2003-2006, volunteers spent over 1,000 hours on mapping and control of invasive species. Nine hundred acres were surveyed for 24 high priority invasive weed species and 10 species from the refuges priority list were mapped. This years proposal emphasizes the continued capacity building of the volunteer-supported invasive weed mapping and control program. With funding from this grant the Volunteer Weed Eradication Event developed in 2006 will continue at the south bay units. This annual event is focused on eradication of early detection species. Several new weed eradication events will be developed in the northern units. The events will focus on invasive annual grasses which threaten the habitat of two Federally listed endangered plant species, Humboldt Bay wallflower and beach layia. Surveying the southern units for high priority species will continue. Several early detection species, Lotus uliginosus, Senecio sylvaticus, and Erichtites glomerata will be mapped in the Hookton Slough Unit. Volunteers will gather literature on the life history and distribution of these species to aid in the assessment of their impacts to the estuarine ecosystem.

Describe the type of work the volunteers performed. (Up to 150 words)
Volunteers were trained in the use of PDA/GPS units using the Nature Conservancy's WIMS program and ArcPad. The volunteers surveyed a total of 227 acres for 25 high priority invasive weed species. Volunteers attended the second annual invasive weed removal event at the Salmon Creek Unit, HBNWR.

How useful was this program for meeting refuge invasive species objectives and how can it be improved?
The project is still in progress. There will be volunteer annual grass removal event in the spring and some additional mapping. I will complete form and recommendations then.
