Tucked away in Englewood MetroPark is a unique woodland area, a remnant swamp forest. Visitors can follow the yellow trail from the trailhead in East Park that will lead to a boardwalk into this wet area. The area supports an unusual population of trees, including black ash, swamp white oak and pumpkin ash. This remnant swamp has been dedicated as a State Natural Landmark in recognition of the occurrence of pumpkin ash, a tree rarely found in Ohio.
