To help fund the restoration of the 7,200-acre Kankakee Sands Wetland Preserve in northwest Indiana, AES created a restoration plan in the late 1990s that called for the establishment of a 100-acre wetland mitigation bank on the site.
In 2012, The Nature Conservancy received its permit to create the wetland bank with approximately 90 acres of wetland mitigation credits permitted in the Iroquois River and Kankakee River watersheds.
Construction of the bank in 2012-13 involved the filling of 1.9 acres of agricultural ditches to restore hydrology to the site. AES crews seeded 90 acres of restoration to wet prairie with another half-acre of wet prairie buffer and 9.4 acres of mesic prairie.
Hydrology monitoring began in June 2013, with vegetation and hydrology monitoring anticipated to continue through 2018.
The Nature Conservancy Kankakee Sands wetland mitigation bank includes objectives for regulatory, restoration, and public benefits.
The regulatory objective is to provide the availability of mitigation credits for use by public and private entities for wetland impacts within the service area.
The restoration objective is to create, restore, and enhance important wetland and wildlife habitat.
The public benefit objective is to improve passive recreation access and opportunities to learn and live with nature in healthy ecosystems.
