Oakwood Bottoms Greentree Reservoir

Within the Shawnee National Forest, Oakwood Bottoms is a 3700 acre greentree reservoir; bottomland forest artificially flooded to imitate natural flooding of the river bottoms during the Fall/Winter to provide forested wetland habitat for migratory waterfowl and other wetland dependent species.  The greentree reservoir is among a larger 12,000 acre block of bottomland hardwood forest in the Big Muddy River floodplain.  The Big Muddy River bottomlands is the largest contiguous bottomland forest in Illinois and for many mile up and down the river. 

The site  has been designated by the National Audubon Society as an Important Bird Area and by the Central Hardwoods Joint Venture as a wetlands focus area.
