Wetlands are a significant factor in the health and existence of other natural resources of the state, such as inland lakes, ground water, fisheries, wildlife, and the Great Lakes.  Michigan's wetland statute recognizes the following benefits provided by wetlands:

• Flood and storm control by the hydrologic absorption and storage capacity of wetlands.
• Wildlife habitat by providing breeding, nesting, and feeding grounds and cover for many forms of wildlife, waterfowl, including migratory waterfowl, and rare, threatened, or endangered wildlife species.
• Protection of subsurface water resources and provision of valuable watersheds and recharging ground water supplies.
• Pollution treatment by serving as a biological and chemical oxidation basin.
• Erosion control by serving as a sedimentation area and filtering basin, absorbing silt and organic matter.
• Sources of nutrients in water food cycles and nursery grounds and sanctuaries for fish.

These benefits, often referred to as wetland functions and values, often play a vital role in recreation, tourism, and the economy in Michigan.  According to a 1991 United States Fish and Wildlife Service Wetland Status and Trends report, over 50% of Michigan’s original wetlands have been drained or filled, thereby making the protection of remaining wetlands that much more important.
