Maryland Coastal Bays Program As a National Estuary Program, • Maryland Coastal Bays Program (MCBP) is a non-profit partnership among the towns of Ocean City and Berlin, the National Park Service (NPS), Worcester County, the U.S. Environmental Protection Agency, and the Maryland Departments of Natural Resources, Agriculture, and Planning. One of only 28 such programs • nationwide, our goal is to protect and enhance the watershed, which includes Ocean City, Ocean Pines and Berlin, and Assateague Island. East of Route 113, the 175-square mile • watershed is home to the treasured resources of the St. Martin River, Newport Bay, Assawoman Bay, Isle of Wight Bay, Sinepuxent Bay, and Chincoteague Bay.

Range & Habitat • Live in coastal salt marshes, tidal creeks, estuaries, and brackish marshes along the East and Gulf coasts. • Found from Cape Cod, Massachusetts to Corpus Christi, Texas. ❖ Seven subspecies found within this range. ❖ Northern Diamondback Terrapin range is from Cape Cod, Massachusetts to Cape Hatteras, North Carolina. ❖ Fun Fact: The Diamondback Terrapin is also found in Bermuda! This population has not been assigned a subspecies, but mtDNA testing shows it is closely related to the Carolina subspecies.

Troubles Facing Terrapins • Inadequate population information – Classified “Apparently Secure” in Maryland • Habitat loss – Living space – Nesting sites – Food • Vehicle Strikes – Boats – Cars • Predation • Crab traps – Bycatch Reduction Devices (BRDs) help prevent terrapin drownings http://www.turtlejournal.com/?p=6464

Reporting Information • All forms will be available at: http://www.mdcoastalbays.org/terrapin-project • All data is important even when it’s negative! Be sure to report the absence of terrapins and location surveyed as well as presence!
What to Expect • Likely only the head will be visible. • Observe with binoculars. If needed, go forward slowly to see if the head disappears underwater. If it does, it’s a turtle! If not, it’s probably a stick.
