Wetland Ecosystem: Wetlands are areas where soil is wet or soaked with water for at least part of the year, supporting a variety of plants and wildlife that are adapted to live in water or wet conditions. Unfortunately, over the past 200 years more than half of Michigan’s wetlands have been destroyed by filling or draining them to provide land for farming, development, or to get rid of mosquitoes. Today, people recognize the importance of wetlands for the services they provide, including flood and erosion control, water purification, and habitat for wildlife. In this module, learn about the types of wetlands, where they are found in Michigan, what lives in them, and why they are so important.
