Title: Hydrologic restoration of historically drained wetland in the Evansville Wildlife Area
Abstract: The Wisconsin DNR In-lieu Fee Program (Wisconsin Wetland Conservation Trust; WWCT) recently completed earthwork with the goal of restoring vegetation and hydrologic function on 80 acres of a historically farmed and drained wetland complex in the DNR-owned Evansville Wildlife Area in Rock Co. With the site's unique landscape position, DNR staff & Heartland Ecological Group realized a goal of full remediation of known drainage features along a seepage slope continuum from upland to surface water by breaking 20,000 feet of clay tile, scraping acres of Phalaris arundinacea sod for ditch fill, and level-filling 3,500 feet of deep ditch. While this restoration is far from complete, I will walk through critical data-gathering steps, planning considerations, and lessons learned for those considering hydrologic remediation of a drained site.
