PROJECT BACKGROUND INFORMATION



Project Title: Eradication of outlier populations of Spartina densiflora in Humboldt Bay
Region: 8
Station: Humboldt Bay NWR
Contact Person:

Project Description:
(Up to 250 words)
Control of Spartina densiflora in HBNWR was begun with a pilot project in 2004 and has continued with both internal and external grants, resulting in a successful mechanical methodology that kills all mature Spartina and suppresses re-invasion. The refuge CCP calls for the eradication of Spartina on the refuge, as a model for the regional eradication of this species in the Humboldt Bay and Eel River estuaries. Volunteers are most strategically used for manual removal of isolated, outlier populations of Spartina, and in this context the proposal is for early detection/rapid response (because without immediate action these will become substantial occurrences). We have previously mapped all outlier populations, which are scattered throughout the Table Bluff, Hookton Slough, and Salmon Creek Unit. During the summer of 2010 we will organize 3 large volunteer events, one in each of these units. Based on our success with last year’s volunteer event, we can expect up to 100 volunteers per event. All work will be carried out in summer 2010.

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
Volunteers removed S. densiflora mature plants using shovels, and removed juveniles with trowels. The work was done both during organized, large volunteer days, and by volunteers coming out on their own. Removal of large plants was done in areas behind dikes with limited tidal exchange. Removal of juveniles was done on the salt marsh at low tides. Volunteers wore rubber boots and gloves. The large volunteer days involved extensive publicity, including car pooling and van transportation, and a barbeque provided by the Friends group. All volunteer received extensive education.In addition, special walks were held at to take the public out on the salt marsh. A restoration pictorial guide was developed identifying common salt marsh natives, and the invasive Spartina, and the methods involved in restoration. Media were invited and attended the large events.

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).
Maps were produced showing all Spartina rmeoved by volunteers. Work was done in two areas....juveniles were removed at the Lanphere and Ma-le'l Dunes Units over 20 ac of salt marsh, and mature plants were removed at the Hookton Slough and Salmon Creek Units of HBNWR.
Number of Acres Treated: 30
Number of Acres Inventoried and/or Mapped: 30
Number of Acres Restored: 30
