Project Description:
(Up to 250 words)
Volunteers worked with staff to survey for and treat 17 different invasive species within the Willamette Valley Refuges (Ankeny, Baskett Slough and William L. Finley). Approx 1500 acres (including 45 miles of roadsides and trails) were treated for invasives. An additional 400 acres were surveyed for presence of specific target invasive species. Ten acres were replanted with native forbs following treatments.

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).
75 % of the mature tansey ragwort plants were removed prior to seed dispersal 45 miles of roadsides/trails were mechanically/chemically/hand treated for multiple invasive species Meadow knapweed chemical treatments were considered 80% effective False brome was almost eradicated but most importantly prevented from spreading Oyeye daisy handpulling prevented spread but was ineffective as eradication Hand pulling English ivy 95% eradication where treated
Number of Acres Treated: 1500
Number of Acres Inventoried and/or Mapped: 400
Number of Acres Restored: 10


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?
Very useful towards containment and control of some invasive species. Any funding dedicated to invasives including this program is productive and should be considered part of base refuge funding.
