While out on a drive along Delaware Bay friend of Conserve Wildlife Foundation Jim Wright has an unplanned encounter with our biologist Larissa Smith and several baby terrapins.
On his blog Jim says “(Larissa) explained that these tiny terrapins cross this road every late May. We helped save four of the little turtles — including three that would have likely been crushed by a giant tractor-trailer headed for a marina. Alas, we found a few crushed little guys on the way.”
To the trained eye, it was clear Kevin Courts and Michael Riff were illegal terrapin harvesters.
The Hatboro, Pennsylvania, men, one shirtless, were parked next to a marsh off Sea Isle Boulevard last July, with six nets and a long pole leaning against their green truck, the state said. A conservation officer who approached them spotted a turtle crawling under the driver’s side seat and found a cooler packed with hatchlings.
Derelict fishing gear continues to plague the depths of Barnegat Bay. Often lost through storm events or due to boat traffic, lost or abandoned crab pots (ghost pots) become an unintentional deathtrap for a variety of marine species and reduce otherwise harvestable resources. CWF and their partners at MATES, Stockton, and ALS have been working to recover lost pots in Barnegat Bay since 2015.
Over the course of the last three field seasons, 1,300 crab pots have been recovered and their bycatch has been extensively documented. Notably, CWF and MATES have been focusing on how to further help northern diamondback terrapins who often find themselves caught in ghost pots. In 2016, one pot contained the remains of 17 terrapins.
As we enter the fourth field season of pot collections, the project hopes to not only recover as may pots as possible, but also to glean further information on how the pots move in a variety of substrates and under a variety conditions. To bring further awareness to the issue, CWF teamed up with the awesome folks at Citizen Racecar to produce a short informational film about ghost fishing and its effects on Barnegat Bay.

This project is funded primarily by the National Oceanic and Atmospheric Administration, with additional support by the New Jersey Corporate Wetlands Restoration Partnership and New Jersey Department of Environmental Protection. Covanta and Schnitzer Steel also support the project by recycling the metal in the retrieved crab pots.

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!
