Project Title: Control Canada Thistle

Project Description:
(Up to 250 words)
Over the past several years, Canada thistle has become established on many acres of the refuge where the soil is moist enough to allow germination of the seeds. Canada thistle invades, dominates and suppresses other plants. Canada thistle does not do well in this climate if some efforts to control it are taken and competing desirable plants are allowed to become established. The refuge has been aggressively attacking Canada thistle for five years, however, there are areas that are not being addressed due to low staffing and funding. Some areas are physically not accessible due to dead timber that was flooded several years ago. Canada thistle is fast becoming the dominant plant in these timber areas. Kirwin NWR is recognized by the American Bird Conservancy as a Globally Important Bird Area. Control of Canada thistle will incorporate the latest techniques. Research has led to the following suggested actions: control burn to release seed bank of Canada thistle, allow physical access to the area, broadcast and spot treat with herbicide, assess and retreat with herbicide in following years. Planting competing desirable vegetation (grass/forbs) will occur in selected areas. Early Detection Rapid Response: EDRR will include training a minimum of 7 volunteers to identify and map invasive plants that are known to exist near the refuge but currently do not occur on the refuge. These plants include purple loosestrife, sericea lespedeza, leafy spurge, and Russian knapweed.

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
Volunteers were trained to identify the above listed invasive plants. Then they searched for those plants on the refuge. If/when those plants were found, refuge staff would go out and assess the extent of infestation and take appropriate action.
Total Number of Volunteers: 14
Total Number of Volunteer Hours: 560
List both new and existing partnerships utilized in this project. (Up to 150 words).

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).
Throughout the project 2,100 acres were inventoried and mapped. Of the acres inventoried, 750 were identified as having Canada thistle. Those acres were treated with herbicide. None of the other invasive plants were observed in the inventoried area.
Number of Acres Treated: 750
Number of Acres Inventoried and/or Mapped: 2,100
Number of Acres Restored: 160


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 needed resource work on the ground for mapping existing invasive plant locations and or early detection of other invasive plants.
