The preserve protects one of the last remaining examples of a natural barrier beach along the Ohio shoreline of Lake Erie.
The marsh acts as a natural water filtration system, improving water quality for the adjacent Sandusky Bay and Lake Erie.
Over 300 species of birds have been recorded within the boundaries of the preserve due to its location on a major migration flyway.
The preserve is home to the bald eagle, which has historically nested within the protected confines of the property.
The sandbar separating the marsh from the lake is dynamic, shifting shape regularly due to lake currents and ice movement.
Ecologists recognize the site as a significant remnant of the coastal marshes that once dominated the southern Lake Erie shoreline.
The preserve features a specific habitat zone known as a 'dune community' which supports rare coastal plant species.
Sheldon Marsh State Nature Preserve encompasses 472 acres of protected coastal wetlands, barrier beach, and upland forest along the shore of Lake Erie. The primary trail is a 1.2-mile paved path that traverses through diverse habitats, leading visitors from an upland hardwood forest to the marsh and beach. The preserve is a vital stopover for migratory songbirds, raptors, and waterfowl, particularly during the spring and autumn migration seasons. The landscape includes a protected lagoon and sandbar that serve as a natural nursery for Lake Erie fish species. Rare wildflower species inhabit the forested areas, including several varieties of native orchids. The site is managed by the Ohio Department of Natural Resources to protect the fragile ecology of this coastal barrier ecosystem. It serves as a significant site for birdwatchers tracking migratory patterns across the Great Lakes region.

Bring binoculars for birding, as the marsh visibility is best from the designated path edges.
Apply mosquito repellent during summer months, as the wetland environment creates significant insect activity.
Stay strictly on the paved path and boardwalks to avoid trampling sensitive wetland vegetation or disturbing nesting wildlife.
Do not attempt to walk on the soft, unstable mudflats in the marsh, as they are protected and dangerous.
Stay on marked trails; dogs are prohibited; do not collect plants, shells, or wildlife; carry out all trash.
