Mentor Marsh State Nature Preserve

The parking lot on Headlands Road at Mentor Marsh State Nature Preserve in Lake County will be closed for re-paving from Thursday, October 10 through Saturday, October 12.

Preserving 646 acres in Lake County

Mentor Marsh, designated as a National Natural Landmark in 1966, occupies an ancient abandoned channel of the Grand River.

A beech-sugar maple forest occupies the higher elevations bordering the marsh. At the eastern edge of the preserve, there is a mixed oak swamp forest, a forest type destroyed in most parts of the Lake Erie region.

The most extensive plant community type is an emergent wetland dominated by reed-grass or Phragmites. This is the largest Phragmites marsh in Ohio. The area provides habitat for a diversity of wildlife species.
