Grant Awarded:

$168,000

Lake Basin(s):

Michigan

Project Location(s):

Wisconsin DNR land in the Upper Fox River Basin within Marquette, Adams, Calumet, Columbia, Fond du Lac, Green Lake, Winnebago, and Waushara Counties, WI

The Wisconsin Department of Natural Resources (DNR) is controlling invasive species on wetland habitat on three wildlife areas and 12 State Natural Areas in east–central Wisconsin.  This work is aiming to improve wetland habitat on the 925 acres where control is occurring and also helping to protect the 22,415 adjacent acres by preventing their colonization by invasive species.  The project includes the control of reed canary grass on 406 acres, common and glossy buckthorn on 300 acres, phragmites on 117 acres, and narrow-leaved cattails on 102 acres.  Control techniques include aerial spraying with a helicopter, boom spraying, hand treatments with backpack sprayers, cut stump treatments, and buckthorn mowing with a tracked vehicle. Potential ecological benefits of the project include:  1) protecting high-quality wetlands that comprise the largest state owned tracts in the Upper Fox Basin; 2) protecting and maintaining habitat quality for 24 Species of Greatest Conservation Need and 21 rare species associated within the project area; and 3) preventing further habitat degradation in adjacent areas by eliminating sources for phragmites, reed canary grass or buckthorn.
