Since 1982, the 333-acre Romeoville Prairie Nature Preserve has been protected by a combination of District purchases, land donations, leases, and conservation easements within the eastern portion of the Village of Romeoville north of 135th Street/Romeo Road. Romeoville Prairie lies adjacent to the District's Centennial Trail and Isle a la Cache Preserve as part of the protected greenway along the river.

Romeoville Prairie was dedicated as a State Nature Preserve in 1984 to acknowledge the significance of its wet to mesic dolomite prairie, marsh, sedge meadow, springs, fens, and floodplain forest on shallow soils over limestone bedrock. Prescribed burning and brush cutting by Forest Preserve Resource Managers started in 1985 to maintain and improve the health of these plant communities. There has been an emphasis on hydrological control and the expansion, enhancement, and monitoring of habitat for daisy and leafy prairie clover.

There is currently no public access or recreational facilities at Romeoville Prairie Nature Preserve.
