Third Haven Woods

Maryland / DC

An unusually old hardwood forest on Maryland's Eastern Shore.



Third Haven Woods is one of the largest single blocks of forested upland not used for timber in the central Eastern Shore. It is a remnant of the forests that once covered much of the Delmarva Peninsula.

Although still relatively young, Third Haven will become an excellent example of old-growth forest in several hundred years.

The preserve provides habitat for a small population of the Delmarva fox squirrel (Sciurus niger cinereus), a recovering endemic subspecies that has been federally listed since 1973.  

There are no facilities, trails or established parking areas at this preserve.
