We all can make a difference to help conserve northern diamondback terrapins. This beautiful species is a symbol of our coast – and now more than ever, we need to be sensitive to our incredible coastal estuary ecosystems!

Here are some ways that you can help make a difference to protect this amazing species:

  • Slow down, don’t tailgate, and be aware while driving in coastal areas from May through July.
  • If you see a terrapin on the road, pull over, put on your hazard lights and carefully help the turtle cross in the direction it is going. Please be careful and use your best judgement and do not get in front of a motor vehicle to stop them on area roads. Do not jeopardize your own safety for a turtle.
  • If you go crabbing and use commercial-Maryland style crab pots, use BRDs or “bycatch reduction devices” to prevent terrapins from getting trapped in them. Use line that sinks to prevent a crab pot from becoming lost. Abandoned crab pots can trap and kill a ton of marine life over time, including blue claw crabs, many species of fish, and terrapins.
  • Talk to others to educate them about terrapins and their role in the ecosystem. You can learn all about them in our Online Field Guide!
  • Volunteer with CWF to patrol roadways and take part in other volunteer actions in Southern Ocean County, Atlantic County, and Cape May County! We really need your help – so please contact us if you, your business, or your civic group is willing to help save the incredible diamondback terrapin!
  • Donate to CWF’s diamondback terrapin program. Any amount would help greatly! Click here and note Terrapin in the PayPal note, or you can mail a contribution to Conserve Wildlife Foundation, 501 East State Street, P.O. Box 420, Mailcode 501-03E, Trenton, NJ 08625-0420.

How to See Terrapins in the Wild in New Jersey

During their nesting season, Northern diamondback terrapins are usually pretty easy to spot along the coast of New Jersey, and throughout their range. They are beautiful turtles with very unique coloration.

Individuals vary in coloration, but in general, their upper shell, or carapace, is dark with a diamond shaped pattern on it. Their lower shell, or plastron, is a light yellow/green color. Their skin is a grey color with black spots that vary highly between individuals. Almost all have a light upper mandible.

From May through July, spotting a terrapin is pretty easy!

Females leave the protection of the coastal waterways to find suitable nest sites to lay eggs. They seek areas with sandy soil, like dunes, parking lots and road shoulders. When our barrier islands were developed, roads were created to access those islands.

The creation of these roads also increased the amount of available nest sites for terrapins. But the development itself actually decreased the amount of suitable nesting habitat for them overall. Much of our coast is now bulkheaded.

Bulkheading restricts the natural movement of terrapins and limits their ability to find suitable nest sites. So, now they must take what they can get: roadsides. Nesting on the edges of roads is a perilous journey for terrapins. The vehicles that travel on those coastal roads may have careless drivers behind the wheel.

Terrapins may be found in many different places along the coast, especially roads that criss-cross saltmarsh. Use extreme caution in trying to spot terrapins on active roads used by vehicles – not only to avoid driving over terrapins, but for your own safety and that of other drivers or pedestrians.

Some widely used locations include Avalon Boulevard and other west-east highways connecting the mainland with barrier islands and peninsulas. Many coastal areas in Cape May also feature high numbers of terrapins, while Monmouth County, Ocean County, and Meadowlands coastal regions feature plenty of terrapins as well.

However, one of the best places to view terrapins during their nesting season is inside the 5,000+ acre Great Bay Blvd. Wildlife Management Area, Little Egg Harbor, NJ. The WMA is located along the coast and is accessible by motor vehicle from the 5 mile long road that ends at the Rutgers Marine Field Station. The road was originally planned to connect the mainland with Atlantic City in the early 1900s. Luckily that plan fell through and the last bridge was never built (road is also called 7 Bridges Road, after the 7th bridge that was never built). There is plenty to see and do out on GBB, at all times of the year. A wide variety of wildlife can be observed from the road, including ospreys, terns, oystercatchers, herons, egrets, and shorebirds. Lots of outdoor recreation opportunites await as well, including crabbing, fishing, and kayaking. There are boat ramps along the road, and all the owners of the local marinas are very nice, including Capt. Mike’s, Rand’s Boats, and Cape Horn Marina.

Viewing terrapins:

Terrapins can be timid if approached, especially when nesting. Please keep your distance when near a nesting female. You wouldn’t want to cause a female to abandon laying eggs in a nest cavity! If she is unable to cover up her eggs with soil then they might become an easy meal for a gull or crow… Watching them nest is fun to watch as they excavate down and lay 8-12 eggs.

If you see one on the road and there is no traffic, slow down or stop and let it cross. If there is traffic coming, stop your vehicle, put on your hazard lights and carefully get out and move the terrapin in the direction it is heading. Terrapins can bite, so be careful and pick it up from the side of it’s shell (called the bridge). Use 1-2 hands to ensure you have a good grip. Sometimes they use their legs to try and get you to let go! Put it on the soft shoulder to be out of harms way. If you have a GPS or a smartphone, record the location and submit us a sighting via our online terrapin sighting form. Data collected from the form will help guide future conservation efforts for them in NJ.

Other great viewing areas:

  • Island Beach State Park
  • Edwin B. Forsythe NWR – Oceanville
  • Wetlands Institute – Stone Harbor
  • Reeds Beach
  • Fortescue Beach

Terrapin Week: Developing a Northeast Regional Conservation Strategy for Terrapins

This story marks the second of five blog stories spotlighting New Jersey’s Diamondback Terrapin – and educating people on the research and efforts being done to protect these fascinating reptiles!

Part 1, Monday, was an introduction into the world of the Diamondback Terrapin. Part 2, today’s blog post, will feature CWF’s research efforts to protect the terrapins. Part 3, on Wednesday, will look at great places to view these beautiful turtles . Part 4, Thursday, will highlight some important ways you can help protect the Diamondback Terrapins.

For the next two years, we will be working with over 30 partners, many of whom are part of the Mid-Atlantic and Northeast regions of the Diamondback Terrapin Working Group (DTWG), assembling data and developing a strategy with the help of their years of expertise working with terrapins.

The overarching goal of the strategy is to help achieve long-term sustainability of terrapins by identifying the species current and historical populations and its habitat (known and unknown occupancy); characterizing and ranking threats; prioritizing focal areas for regional and individual state management; identifying data gaps; and reviewing the regulatory status in each state. The strategy will describe a strategic initiative for implementation of conservation actions across eight states and identify focal areas for conservation. The results of the strategy could be used to solicit additional funding for implementation for more regionally significant areas for terrapins in the future.

We’ve hit the ground running for this project and will convene the partners in meetings later this year at the College of William & Mary in Virginia and Cape Cod, Massachusetts as well as visit states for more local terrapin meetings.

More information on this project can be found on the Northeast Regional Conservation Needs (RCN) Grant Program site.

*The Northern Diamondback Terrapin (Malaclemys terrapin terrapin) in the Northeastern United States:  A Regional Conservation Strategy” is supported by State Wildlife Grant funding awarded through the RCN Program.  The RCN Program joins thirteen northeast states, the District of Columbia, and the U.S. Fish and Wildlife Service in a partnership to address landscape-scale, regional wildlife conservation issues.  Progress on these regional issues is achieved through combining resources, leveraging funds, and prioritizing conservation actions identified in the State Wildlife Action Plans.  See RCNGrants.org for more information.

Its Terrapin Week!

Join us on this fascinating journey into the world of the Diamondback Terrapin

Last week, I drove slowly down a road with no buildings or homes on either side, with only vast salt marsh as far as the eye could see. Over the course of the roughly 10-mile round trip, I passed maybe four other cars. But there was another kind of traveler that I found in abundance – 22 diamondback terrapins crossing the road on the way out, and another 18 of these gorgeous turtles on the way back (although I’m sure I saw some of them twice)!

Amazingly enough, this was a drive along the New Jersey coast in June. If you haven’t guessed it, I was on Great Bay Boulevard in Little Egg Harbor. And if you haven’t been there, now is the time to go – it is a true wildlife spectacle that you have to see to believe.

New Jersey’s coast is filled with wonders during the summer months – wonders that go beyond its crowded beaches, boardwalks, and traffic jams! Believe it or not, the coast still has plenty of nature to be found, often in total seclusion. And diamondback terrapins offer as amazing a wildlife story as any.

So today we kick off Terrapin Week! Read our first installment below for an up-close look at the terrapin’s habitat, appearance, range and status. Then stay tuned for a brand new story each day this week by our terrapin biologists Ben Wurst and Stephanie Egger, with topics including our biologists’ research projects, how our volunteers are making a difference, terrapins across the East Coast, and New Jersey locations where you have the best chance of seeing terrapins in the wild!

Meet the Terrapin

by Stephanie Feigin, CWF Program Coordinator

Northern diamondback terrapins (Malaclemys terrapin terrapin) are native to New Jersey and inhabit the many miles of coastal salt marshes and estuaries along the Atlantic Coast and Delaware Bay. They exclusively inhabit coastal salt marshes, estuaries, tidal creeks and ditches with brackish water (a mix of both salt and freshwater) which is bordered by spartina grass. They are the only turtle species in the world that is specially adapted to spend its entire life in this type of water.

The northern diamondback terrapin is a medium-sized turtle that varies in length from only 4 to 5.5” in males to 6 to 9” in females. Terrapins have a gray, brown, or black carapace (top of shell) and a lighter plastron (bottom of shell), which is a greenish-yellow. The skin is light to dark gray with black spots and other dark markings. Both sexes have a light colored upper mandible. They are named for their diamond shaped pattern on their carapace. Adult terrapins primarily eat mollusks and crustaceans, including snails, fiddler crabs, and mussels. They also eat blue crabs, green crabs, marine worms, fish, and carrion.

Terrapins are cold-blooded, or ectothermic. They hibernate during the winter and bury themselves at the bottom of or in the banks of creeks and ditches. Studies have shown that terrapins also exhibit a high level of site fidelity or they return to the same territory every year, some even occupy the same small creeks year after year. Terrapins have a very small home range, from Cape Cod, Massachusetts to Cape Hatteras, North Carolina.

In 2001, a status review of reptiles in New Jersey recommended that the Northern diamondback terrapin be listed as a species of special concern in New Jersey. The listing as special concern “warrants special attention because of some evidence of decline” (NJ ENSP-Species Status Listing) and little is known about their actual population status in New Jersey. However, terrapins are still harvested for food in New Jersey and the total harvested annually is not known. Since Terrapins are still considered a “Game” species subject to harvest, the Special Concern designation was never officially applied to the species and will not be until they are re-classified as a “Non-game” species.

Major threats to the health of the population include; habitat loss, mortality from being drowned in crab traps, and road mortality. Each year hundreds of terrapins are killed by motor vehicles throughout their range and here in New Jersey. The Conserve Wildlife Foundation (CWF) and their biologists are working hard to protect these incredible reptiles with their many conservation efforts. We are asking you to “Be Terrapin Aware” while driving along roads in New Jersey’s coastal region, and stay tuned for more posts during Terrapin Week about our efforts to protect these turtles!
