To lay eggs, of course.It’s now the beginning of the annual nesting season for northern diamondback terrapins, the only species of turtle that inhabits the New Jersey coastal estuaries year round, according to Ben Wurst, Habitat Program Manager for Conserve Wildlife Foundation of NJ.

Living exclusively in brackish water, adult females emerge from the protection of their aquatic habitat to find suitable areas to lay eggs, seeking nesting areas with a sandy gravel type substrate above the high tide line, Wurst said.

And that’s where the trouble begins.

“Throughout their range along the coast terrapins face a variety of threats to their survival,” he said, citing a loss of nesting habitat due to commercial and residential development, shoreline hardening, and flooding.

In turn, the loss of habitat in the marsh systems increase the risk of terrapin mortality as they search for adequate nesting areas.

“Terrapins will utilize roadsides for nesting which increases the threat of being hit by motor vehicles,” Wurst said. “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.”

But there are several ways to help.

He suggests that drivers in coastal areas “Be Terrapin Aware” until mid-July, a simple way to avoid striking a turtle in search of a nesting area.

“Terrapins are a great example of a small behavioral change in people — in this case, driving with more awareness on our coastal roads — making a huge difference for an at-risk wildlife species,” said Conserve Wildlife Foundation of New Jersey Executive Director David Wheeler.

“Rescuing a live terrapin (or any other turtle) from the road is a rewarding experience,” the habitat program manager said. “It’s a great way to engage future generations in caring for our terrapins.”
