Project Description:
(Up to 250 words)
Project goals were to train volunteers to conduct invasive species mapping using GPS and GIS technology. Maps with corresponding databases were created describing species composition, percent cover, and extent of invasive species. This information will be used to control and monitor invasive species.
List of Invasives Species Targeted:Common NameScientific Name
  Himilayan blackberry Rubus discolor
Canada thistle Cirsium arvense
Bull thistle Cirsium vulgare
Reed canary grass Phalaris arundinacea

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
Volunteers were trained to use hand-held GPS/GIS units to map invasive species.
Total Number of Volunteers: 8
Total Number of Volunteer Hours: 130
List both new and existing partnerships utilized in this project. (Up to 150 words).
Volunteers were recruited from members of the Friends group and from the general public.


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).
Volunteers were able to map 450 acres on the Atflati Unit of Tualatin River NWR. About 150 acres of invasive species were subsequently treated by either discing or by application of Service approved herbicide by refuge staff. We plan to continue next season by training more volunteers to conduct invasive species mapping and to form a "hot shot" team to combat the most agressive species. In addition, staff will be analizing current data to determine overall composition and entent of invasive species.
Number of Acres Treated: 150
Number of Acres Inventoried and/or Mapped: 450
Number of Acres Restored:


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

Recommendations: (OPTIONAL)
How useful was this program for meeting refuge invasive species objectives and how can it be improved?
This program was very helpful in providing equipment and supplies to enable volunteers to safely conduct invasive species mapping and in the future to help with control objectives.
