In recent years, major national and local attention has focused on conservation of wetlands. There are many complex issues to address related to drainage improvements and the protection of unique ecosystems. Numerous state and federal agencies are involved in some aspect of wetland protection. These agencies include, but are not limited to: the USDA Soil Conservation Service (SCS) and Agricultural Stabilization Conservation Service, the U.S. Army Corp of Engineers, the U.S. Environmental Protection Agency, the U.S. Fish and Wildlife Service, the Ohio Environmental Protection Agency, and various divisions in the Ohio Department of Natural Resources. It is beyond the scope of this publication to address fully the complex issues associated with drainage improvements and the conservation of existing wetlands in Ohio. However, if there are questions in this area, the reader is advised to contact the agencies listed above. A good place to start is with the county Extension office or the local USDA-SCS District Conservationist.
