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

Terrapin Survey

Tuesday, May 28th through Saturday, June 1st

  • Land-based

– From your home, friend’s home (with permission), or contact MCBP for locations – 3 surveys, 15 minutes each

  • Water-based

– Kayak, canoe, or boat – One way run, no time constraint

slide-10

Location

  • We must have your location for the data to

be valuable. If you have a smart phone, you can use one of the apps on the following page.

– Coordinates must be in decimal degrees. – For boat surveys, take waypoints every 10 minutes if no terrapins are sighted. – Land-based surveys may use an address. Please do not access private property.

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!

slide-15
SLIDE 15

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.
