Seven Island Conservation Area is in Mississippi County, two miles southwest of the town of Dorena and 16 miles southeast of East Prairie.
The area can be reached by traveling south on Highway 102 from Highway 80 to Route A, then south to Mississippi County Road 520. A cantilever sign at this intersection directs visitors over the Mississippi River levee and into the area.
The area consists of a nearly 8.5 mile long tract of land that is located outside the front line levee. At it's widest point the area is little less than one mile wide.
The Conservation Department made three separate purchases of land parcels in 1979, 1982 and 1985 to acquire what is now a 1,375-acre area. Of the total, 430 acres are annually rowcropped, 875 acres are forested, sloughs comprise 46 acres and small openings account for the remaining 24 acres.
The area features 3.5 miles of Mississippi River frontage. Because it is not protected by levees, the area floods regularly, enhancing its value as wetland habitat.
Management of the property is presently limited to leaving a percentage of the row crop standing for wildlife consumption and improving the timber through forest management.
In addition to providing important habitat for waterfowl during periods of high water, Seven Island Conservation Area is home to deer, turkey and various songbirds and furbearers. The area also hosts two rare species, the swamp rabbit and Mississippi kite.
