Wetlands

Fifteen wetlands have been restored on campus starting in 1992. They range in size from small ephemoral (temporary) ponds up to 9 acres of surface water. They were constructed through the U.S. Fish and Wildlife Service Wetland Restoration program. These wetland sites, drained years ago for agriculture, were identified by surveying and from topographic maps. Dikes were constructed and field drain tiles were destroyed if present. These wetlands now have many nesting waterfowl as well as chorusing populations of amphibians. All wetlands are surrounded by the other natural areas (prairie and woodlands) to buffer them from agriculture and development runoff. The wetlands are part of the Cannon River watershed and help with seasonal flood control, soil stability and ground water recharge as well as provide valuable wildlife habitat.
