As with many of our conservation projects, they are centered around compassion for a species in need. One of which is the northern diamondback terrapin: a coast hugging turtle who inhabits salt marsh habitat from Cape Cod to Cape Hatteras. In New Jersey they range from the Meadowlands south along the coast and in the Delaware Bay. Terrapins are known to have a very small home ranges and some may inhabit the same small creek for their entire lives. During summer months, females leave the protection of their salt marsh habitat to seek out sandy nest sites above the high tide line. Many times, they encounter a roadway and the results can be deadly.
Northern Diamondback Terrapins (Malaclemys terrapin terrapin) are a native species of New Jersey turtle, inhabiting the brackish waters of the state’s coastal salt marshes and estuaries. The survival of the species depends on the ability of female turtles to access safe nesting habitat every summer, a struggle for the species these days with roadways disconnecting large swaths of their habitat. To help give females a better chance of successfully reproducing, CWF partnered with New Jersey Division of Fish & Wildlife last year to create a half-acre “turtle garden” at a former marina within the Great Bay Wildlife Management Area.
CWF Habitat Manager Ben Wurst took Pat Johnson of TheSandpaper.net to the site recently to survey the success of this new turtle garden and walk through what it takes to save a species like the diamondback terrapin.

It’s diamondback terrapin hatching season in the newest turtle garden established by the Conserve Wildlife Foundation of New Jersey in the Great Bay Wildlife Management Area. Project Manager Ben Wurst has been monitoring the 50 or so nests that were created this spring to protect them from predators so the hatchlings could have a fighting chance of survival.
Last week, Conserve Wildlife joined the American Littoral Society at their annual Parade of Boats event in conjunction with the Operation Oyster program.
Conserve Wildlife, through funding from NOAA’s Marine Debris Program, has spent the last several years in a related effort to clean up Barnegat Bay. Removing derelict crab traps or ghost pots from the bay has been an ongoing initiative. Ghost pots are lost in a variety of ways including improper rigging to buoys and buoy lines cut by passing boat traffic.
The issue spans not only the commercial crabbing industry, but the recreational industry as well. The longer the pots sit on the bottom of the bay the more likely they are to serve as a deathtrap for a variety of marine species. The more marine life that becomes trapped the more the pots continue to attract other marine life. This is of particular concern for Northern Diamondback Terrapins that frequently investigate these pots looking for a quick meal only to be trapped and quickly drown.

Giving kids a head start in learning about nature is the point of Head Start Terrapins, a school course started by the Ocean County MATES program and Conserve Wildlife Foundation of New Jersey. Last October, Ben Wurst, CWFNJ project manager for Bass River and Balanger Creek, picked up seven quarter-sized baby diamondback terrapins from the roadside on Great Bay Boulevard, Little Egg Harbor Township.
Dedicated volunteers help reduce mortality of adult female terrapins

Volunteers Elizabeth and Courtney measure the height of a female terrapins carapace.
Now that Northern diamondback terrapins (Malaclemys terrapin terrapin) are officially considered a nongame species, our work to help conserve breeding adult females is more justifiable. Before July 2016, adult terrapins, including egg bearing females, could be harvested during an open season from November to March. With that said, it was troublesome to know that a 15+ year old female that you helped safely cross a road in summer, could be harvested, shipped to Asia and eaten only a few months later… Now, we can rest (somewhat) easy knowing that the hard work of our dedicated volunteers will live on and help the population grow (there are still many threats to terrapins including collisions with boats, vehicles, poaching, drowning in ghost crab pots, etc…) Continue reading “Reducing Roadkills of Terrapins in S.

Preservation of declining habitat is key to survival of high marsh wildlife

As the sea rises, high areas on the coastal salt marsh will decline or disappear. These areas are higher in elevation and usually consist of more sandy soil. The sandy soil attracts nesting female diamondback terrapins, like many roadsides throughout New Jersey. As we harden shorelines to hold back floodwaters, terrapins will face more dangerous treks to find suitable nesting habitat, unless these high marsh areas are enhanced and elevations raised. For the past five years we have been surveying Route 30 (Whitehorse Pike) during summer months for the occurance of terrapins on the highway. Adult female terrapins enter the roadway while seeking these sandy areas above the high tide line. Most, if not all, do not survive crossing Route 30.

While removing our seasonal (better late than never!) terrapin X-ING signs on Great Bay Blvd. in Little Egg Harbor yesterday, we stumbled upon some tiny northern diamondback terrapin hatchlings. These little guys were hiding or trapped under a very large (and heavy) X-ING sign made from old pallets that someone knocked over (I say guys because they hatched later in the season and it was a very cool August, but some could be girls). At first I didn’t see anything, but upon closer inspection I saw several hatchlings in the vegetation. One, two, three, four, five, six. Then I dug a little with my hand and found two more. The sign had been atop a nest. Continue reading “Photo from the Field”
Conserve Wildlife Foundation of New Jersey Releases a New Story Map: “Turtle Gardens”
By: Michael Davenport, Wildlife Biologist & GIS Program Manager
The northern diamondback terrapin is an imperiled species of turtle found in brackish coastal waters along the northeast coast of the United States. Within New Jersey, much of the nesting habitat once used by terrapins has been lost to development and rising sea level. What little suitable nesting habitat remains is often inaccessible to terrapins due to bulkheads or other construction and road mortality is a major cause of terrapin mortality as they cross roadways seeking nesting sites.
Turtle gardens provide suitable nesting habitat for diamondback terrapins where little natural suitable habitat remains or is inaccessible. By enhancing the existing habitat at a site within the terrapin’s range to meet their nesting habitat requirements, terrapins can more safely lay their eggs within an area specifically set-aside for them.
CWF recently partnered with the Marine Academy of Technology and Environmental Science (MATES) on a pilot project turtle garden on Long Beach Island in New Jersey. The newly released Turtle Gardens story map details this project.
DONATION SUPPORTS CONSERVATION OF NJ’S ONLY COASTAL MARSH TURTLE
by Corrine Henn, Communication Coordinator
Great Bay Boulevard in Little Egg Harbor is a favorite haunt for local fisherman, birders and tourists alike. While many locals and visitors celebrate the summer, Conserve Wildlife Foundation of NJ’s Ben Wurst and his team of dedicated volunteers know that summer can mean something else entirely.
An increase in traffic on Great Bay Boulevard during the summer months threatens the survival of one particular species, the northern diamondback terrapin. Hundreds of female terrapins cross roads adjacent to their native habitat, our coastal estuaries, in search of suitable nest sites each year. Unfortunately, Great Bay Boulevard lacks a formal speed limit and mortality rates as a result of vehicle collisions are just one of the dangers the terrapin face.
“From what I’ve seen and experienced from the beginning of this project is that many more people are more aware of terrapins on the road,” said Habitat Program Manager, Ben Wurst. “It is critical to have the support of the local community as they are the ones who frequent the area the most and can really play a huge role in their long term conservation.”

The Great Bay Terrapin Project has done tremendous work to reduce road kill rates. More recently CWF has been collecting data to monitor the local population by taking measurements and notching individual terrapins as part of a mark-recapture effort. Our volunteers conduct road patrols to collect data on terrapins that are encountered on road and also help ensure that they cross safely. Along the most dangerous part of the road, a barrier fence helps to deter terrapins from entering the roadway. Both the fence and several “Terrapin X-ing” signs, have also aided efforts to curb mortality rates each summer.

Ensuring the future survival of the terrapin is, of course, a collaborative effort. We were especially thankful when Glenn Laborda, Dibyarka Chatterjee and Kristen Schmicker of Absolutely Fish presented Conserve Wildlife Foundation of New Jersey with a $5,000 check from the proceeds they raised throughout the Earth Day weekend in April.

According to Jennifer Ruivo of Absolutely Fish, “People come into the store specifically to see her and are generally much more willing to help, donate, or take information when we have a terrapin in store.” The turtle’s presence in the store garners support by bridging the gap needed for many to see that these animals, our neighbors, are in need of our support.
Following the donation from Absolutely Fish, Absolutely Fish representatives – along with Wurst and CWF Executive Director David Wheeler – conducted a survey of Great Bay Boulevard with CWF intern Carly Sibilia who demonstrated the data collection and notching technique of terrapins.
Stay tuned for post-summer update on CWF’s terrapin projects. And in the meantime, be mindful of your surroundings and be terrapin aware!
ROADS ARE DANGEROUS CROSSINGS FOR SLOW-MOVING TURTLES
by Kathleen Wadiak, CWF Intern
New Jersey is home to a number of turtle species, and this time of year, it is not uncommon to see some of them crossing the road. Slow movers on land, they are not well equipped to avoid the dangers of a busy roadway. If you come across a turtle on one of your streets, what should you do?

First of all, it is important to think of your own safety in addition to the turtle’s. Be sure to pull completely over to the side of the road and to put on your hazard lights. Check for cars, and make sure that you are visible to oncoming traffic.

If you want to move a turtle across the road, there are a few things to keep in mind. To start, remember to never lift a turtle by its tail or limbs, as this can cause serious injury. With most turtles, it is best to pick them up on either side of their shell between the forelimbs and hind limbs. Even small ones may squirm and kick, so try to keep a firm hold and carry them low to the ground to avoid a dangerous drop!
If the turtle is large with a long tail and pointed head, it is likely a snapping turtle and should be met with some extra caution. Try using a blunt object to gently coax it to the roadside, and be careful to avoid touching it anywhere within range of its bite, which can reach as far back as the middle of its body! If you think you need to carry it, hold it with two hands on the shell behind its hind legs, on either side of the tail.

Before you handle a turtle, notice which direction it’s facing. Move it to that side of the street, as it is likely determined to head to a certain site, and will end up in the road again if it is moved away from its goal. This is an especially important point with the many threatened and endangered turtle species in our state. Helping turtles in trouble across a roadway and leaving them to enjoy their natural environment is a great way to ensure that there will be more wild turtles to appreciate for years to come!
