Prairie History

This is a remnant of a sedge meadow complex that was originally about a mile wide and seven miles long.

The site is in the Oak Openings Ohio Prairie Region. (Prairie Regions of Ohio)


226 acres.

Prairie Description

A primary feature is a hydric prairie dominated by several species of sedges, rushes and wetland grasses. It is considered to be Ohio’s best sedge meadow.

The preserve has a mosaic of plant communities influenced by varying water table levels, including: wet tallgrass prairie communities dominated by big bluestem and dense blazing-star; sedge meadow dominated by twig-rush; shrub swamp dominated by shrubby species of dogwoods and willows; grass meadow dominated by blue-joint grass and northern reed-grass; and swamp forest dominated by pin oak and cottonwood.

Visitation Information



The preserve has 1.25 mile handicapped-accessible boardwalk, beginning at the parking lot. This boardwalk does not have kick rails for wheelchairs, so it is suggested that wheelchair users have assistance when using the boardwalk.

Irwin Prairie State Nature Preserve is an example of sedge meadow and wet prairie found in the Oak Openings. It is handicapped-accessible.
