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.
