A 23-acre preserve in Portsmouth in one of the largest wetland areas feeding Great Bay. It has an Atlantic white cedar swamp and provides potential habitat for the Hessel's Hairstreak, a rare butterfly.
From the town of Greenland take 101 East. Turn right onto Ocean Road (this is just before Interstate 95). Travel approximately 1 mile. To the right (50 yards before the railroad) is a wet area which parallels and is West of a driveway just before the railroad. This is the access. Please note that parking for this site is a problem. The best places are the small pull-offs associated with the railroad.
