Project Description:
(Up to 250 words)
Big Lake NWR is a 11,038 acre refuge that consists primarily of wooded swamps and open water. Big Lakes system is so unique that approximately 5,000 acres have been set aside as a National Natural Landmark. Approximately, 2,100 acres of the Natural Area has been included in the Wilderness Preservation System. In the early 1950’s approximately 200 acres of this valuable bottom land habitat was cleared for farming practices by the refuge. Throughout the 1990’s these croplands were reforested with trees; however, these reforested fields and forest edges host a plethora of exotic species.

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
Summer interns and friends members were trained and utilized to conduct weed mapping and assessments. Summer volunteers started the implementation of treatments under staff supervision to remove the exotic species of concern. Additionally, Friends group members were called upon to implement control and donated use of equipment as a cooperative effort.
Total Number of Volunteers: 15

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).
The treatment sites were evaluated through habitat assessments and sites with invasives present were mapped and treated was initiated. Extreme infestations may be mapped and retreated annually. All affected areas will need to be reassessed and spot treated potentially for several years for complete eradication. Approximately 300 acres were mapped, control of mimosa appears complete, all other species will need continued eradication efforts. Along the western boundary of the refuge, early detection was very important to prevent the spread of invasives into the refuge interior and the entire western boundary was effectively treated.
Number of Acres Treated: 40
Number of Acres Inventoried and/or Mapped: 200
Number of Acres Restored: 40


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