Places We Protect

Third Haven Woods

Maryland / DC

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

COVID-19 Update (June 3, 2020)

TNC’s public preserves in Maryland remain open. We ask all visitors to observe our preserve access guidelines and follow current health and safety precautions, including guidance from the Maryland Department of Health and the Centers for Disease Control (CDC), including maintaining a distance of at least 6 feet from others (social distancing).

Parking may be limited at many of our preserves. If parking areas are full, please plan to return to the preserve another day.

Thank you for helping us in our efforts to protect our visitors’ health and well-being.


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.

What to see: Plants

  • Flowering dogwood
  • Southern arrow-wood
  • American holly
  • Pepperbush
