The diamondback terrapin is one of the most beloved species of New Jersey’s coastal salt marshes. Their popularity has not protected them from the rapid development of our coast however, and climate change is calling their future into question.
Terrapin and human interaction has been fraught with peril for the turtles for a long time. They used to be considered a delicacy and were almost wiped by the 1920s when, in an odd turn of events, they were saved by prohibition. Turns out that once terrapin stew no longer featured copious amounts of alcohol, people noticed they did not, in fact, taste very good.
The fourth episode of our podcast, State of Change, “The Terrapin’s Troubles” features John Wnek, Project Terrapin coordinator and supervisor and researcher at the Marine Academy of Technology and Environmental Science (MATES), and Ben Wurst, Conserve Wildlife Foundation (CWF) habitat program manager.
Public urged to use caution while driving in shore areas this summer

Each year in late May and early June the annual nesting season for northern diamondback terrapins begins. This unique species of turtle is the only one to inhabit our coastal estuaries year round. They live exclusively in brackish water.
During this time of year, adult females emerge from the protection of their aquatic habitat to find suitable areas to lay eggs. They seek nesting areas with a sandy gravel type substrate that’s above the high tide line.
Throughout their range along the coast, terrapins face a variety of threats to their survival. Terrapin nesting habitat has been lost due to commercial and residential development, shoreline hardening and flooding which poses a greater threat to these limited nesting areas. Loss of terrapin nesting habitat along marsh systems put terrapins at greater risk of mortality as a result of increased time searching for adequate nesting areas (Winters 2013). Terrapins will utilize roadsides for nesting which increases the threat of being hit by motor vehicles. Roads are essential to our daily life but they often are barriers to wildlife, especially small critters like terrapins. Studies have shown that adult females have become less abundant and smaller from road mortality. (Avissar, 2006).
You can help terrapins several ways during the nesting season. Driving more cautiously from now until mid-July is a simple way to be more aware of terrapins crossing the roads. Nesting peaks during the full and new moon cycles and they’re more active during the high tide (less distance to travel on land to nest sites). We ask drivers in coastal areas to “Be Terrapin Aware” while driving in these areas. If you find a terrapin crossing the road use these steps to help it cross safely:
Stay safe. Never put yourself at risk! Make sure that you do not endanger yourself, or others, by walking into traffic.
When safe to do so, pull your car over and onto the shoulder, if possible. Turn on your hazard signals.
When safe to enter the roadway, approach the turtle and pick it up by grabbing its shell with both hands between its front and hind legs. HOLD ON – Terrapins have strong legs!
It is important that you move the turtle in the direction that it is heading. They are not always headed directly towards water. They will turn around if you put them in the wrong direction, so work with their instincts.
Place the terrapin off the road onto the soft shoulder (dirt or grass).
If you have a GPS or a smartphone then record your location and submit your sighting on our website.
Please do not move a terrapin long distances to “somewhere safe!” They have very small home ranges and moving them will only hurt them.
Rescuing a live terrapin (or any other turtle) from the road is a rewarding experience. It’s a great way to engage future generations in caring for our terrapins.
You can also help terrapins during the nesting season by supporting our new “Turtle Gardens” project. CWF, in partnership with the Marine Academy of Technology of Environmental Science, will develop and implement an educational initiative to promote terrapin nesting habitat enhancement. These “Turtle Gardens” will raise awareness of the benefit of living shorelines to terrapins and other coastal wildlife, as it relates to sea level rise and coastal flooding within the Barnegat Bay Watershed. Turtle Gardens for terrapins are patches of sandy nesting habitat above the high water line that are less susceptible to flooding. They also reduce the risk of road mortality. We will be having informational training sessions for those that would like to volunteer for monitoring Turtle Gardens or have property that would support a Turtle Garden. Information on these sessions will be announced in mid-June.
In addition, we will also be looking for terrapin sighting information with Project Terrapin in Berkeley and Lacey Townships in Ocean County as part of an initiative to fill in data gaps for this species on the mainland. If you see terrapins in these locations please report your sightings online.
