Fens are peatlands whose dominant plants are sedges (tall grass-like plants) accompanied by grasses, brown mosses and flowers such as iris. A fen is fed by streams or by ground water. Fens are less acidic and generally richer in nutrients than bogs. The water table is usually at or above the surface of the peatland.

are wetlands found in northeastern Illinois and along the Illinois River.
