Many wetlands are important fish spawning and nursery areas, as well as nesting, resting and feeding areas for waterfowl.
Wetlands have been called “nature’s kidneys” because of their ability to filter impurities from water. Sediment settles out of runoff and dissolved contaminants bind to plant surfaces or are transformed, resulting in improved water quality. Wetlands perform other valuable functions including reducing flood flow and shoreline erosion control.
The Wetland Ecology Group performs wetland research with the goal of developing wetland biocriteria and wetland water quality standards for Ohio. Funded largely by U.S. EPA grants awarded to assist states with the development of water quality standards for wetlands, the Wetland Ecology Group's work aids and strengthens the basis for regulatory decisions made by the 401 Water Quality Certification Section.
