Description
Momence Wetlands Land and Water Reserve consists contiguous floodplain forest and upland forest adjacent to the Kankakee River. It is within the Momence Wetlands complex, which is the last remaining vestige of the Grand Kankakee Marsh in Illinois that once encompassed nearly a million acres extending on both sides of the Kankakee River in Illinois and Indiana. The portion of the Kankakee River which flows through the site is recognized by the Biological Stream Characterizations as one of Illinois’ finest water resources and containing outstanding biological features. The high-water quality and endangered species habitat is due in large part to the filtering of sediments and agriculture runoff provided by the reserve’s forests. Only a few large tracts of floodplain forest remain in this part of the state, making the site an outstanding and highly significant remnant of Illinois’ natural heritage. Wet floodplain forests are dominated by pin oak, silver maple, swamp white oak, river birch, and green ash. The upland forest is composed primarily of white oak, black oak, white ash, and shagbark hickory. These forests also provide habitat for several area-sensitive forest species, and three state listed species. Notable plant species include the swamp cottonweed, pumpkin ash, and climbing hempwood – all of which are southern swamp species that have their only known northern outliers in the Momence Wetlands.
