PROJECT BACKGROUND INFORMATION



Project Title: Common buckthorn control at Shiawassee NWR

Project Description:
(Up to 250 words)
Shiawassee Refuge protects 4,225 acres of forested wetland. These wetlands provide breeding habitat for many Partners In Flight priority species, including hooded merganser, black-billed cuckoo, yellow-billed cuckoo, yellow-throated vireo, wood thrush, prothonotary warbler, and Baltimore oriole. Common buckthorn is a recent non-indigenous invasive plant on the refuge. This species occurs on approximately 100 acres of forested wetlands and has become the dominant understory woody plant in some areas. Consequently, habitat quality for these bird species has been degraded and the threat of more widespread degradation is imminent. Refuge staff implements buckthorn control on 5 – 10 acres per year via mechanical and chemical methods and occupied acreage is gradually diminishing. This effort is assisted through practices by adjacent farmers to eradicate buckthorn because of its role in the lifecycle of the soybean aphid. However, increased resources are required to eliminate common buckthorn from the refuge. The refuge has begun to incorporate volunteers into this program by providing herbicide applicator certification, equipment, herbicides, and supervision. Volunteers will also be used for more precise GPS mapping of existing treated and un-treated buckthorn stands and to conduct surveys to identify newly invaded sites. Adjacent farmers eradicate buckthorn which reduces re-colonization potential on the refuge.

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
Volunteer completed pesticide applicator certification. Volunteer also applied foliar and basal herbicide treatment to common buckthorn and Japanese barberry on approximately 50 acres of refuge lands. Adjacent farmers continue to eradicate buckthorn which reduces re-colonization potential on the refuge. Refuge receives significant recognition for our efforts from farmers since it helps their efforts.

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).
Common buckthorn follow up treatment completed on 30 refuge acres treated in previous years. Initial control implemented on 54 new acres. New control areas mapped in refuge GIS program. Also, 80 acres of Japanese barberry, 40 acres of autumn olive, 64 acres of Phragmites and 36 acres of garlic mustard treated.
Number of Acres Treated: 304
Number of Acres Inventoried and/or Mapped: 304
Number of Acres Restored: 304

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 enabling the refuge to make a meaningful impact toward common buckthorn control. Previously we only treated 10-20 acres per year. This program enabled the refuge to treat 84 acres. Also, 220 acres of other important invasive plants were treated, including japanese barberry, autumn olive, Phragmites, and garlic mustard.
