The preserve contains a rare 'flatwoods' forest type, characterized by poorly drained soil that supports unique plant communities.
The property was donated to the Lake County Forest Preserves by the Edward L. Ryerson family, former owners of Inland Steel.
The site includes several ancient trees, some of which are centuries old, predating the surrounding suburban development.
Its location along the Des Plaines River serves as a critical stopover for migratory birds in the Mississippi Flyway.
The historic Ryerson log cabin and estate were designed to integrate seamlessly into the surrounding wilderness.
The Edward L. Ryerson Conservation Area is a 547-acre nature preserve in Riverwoods, Illinois, featuring one of the last remaining high-quality remnants of northern flatwoods forest in the state. Managed by the Lake County Forest Preserves, the site encompasses a diverse ecosystem of floodplain forests, prairies, and vernal ponds along the Des Plaines River. It serves as a designated Illinois Nature Preserve, protecting ecologically sensitive landscapes that are largely untouched by modern development. Visitors can explore approximately 6.5 miles of trails, including the accessible boardwalks through the forest floor. The area is home to the historic Ryerson Home, built in the early 20th century in a distinct architectural style. The preserve acts as a significant wildlife corridor, providing habitat for deer, owls, and migratory birds.
The elevated boardwalk trails during autumn or the historic estate exterior during late afternoon light.
Wear waterproof footwear during spring or after heavy rain, as the low-lying trails are prone to flooding and mud.
Check for ticks and mosquitoes, as the dense forest environment is highly active during summer months.
Stick strictly to the marked trails to avoid damaging the sensitive ecosystems of the designated Nature Preserve area.
Do not attempt to walk off-trail or enter the river, as the protected ecological zones are fragile and easily damaged.
Trails are generally open from sunrise to sunset daily, but the Ryerson Welcome Center may have restricted days during winter.
Stay on marked trails at all times, do not collect plants or wildlife, and pack out all trash.
