This summer, I had the chance to volunteer for the Great Bay Terrapin Project to help survey the local terrapin population within Great Bay Boulevard Wildlife Management Area. Being able to assist a vulnerable population was incredibly fulfilling and I personally was able to learn a lot about their behavior during this incredible time. I got to see firsthand just how many female turtles crossed that road to lay their eggs, but unfortunately that also showed me just how many were injured or killed by reckless, inattentive, or outright malicious drivers. One thing I realized during this is just how hardy of an animal the terrapin is. I saw individuals with massive chunks taken out of them, bite marks, claw marks, and huge gashes from boat propellers forever etched into their shells. I realized that despite their vulnerability in early life and extremely slow growth, the defense of their shell and their insane ability to recover from injuries left them with very few threats for a long time. Even many major boat injuries are recoverable, emphasizing the severity of the threat posed by automobiles specifically.

When we founded the Great Bay Terrapin Project, our goal was to reduce roadkills of adult female northern diamondback terrapins. This was largely due to personal observations of multiple roadkills during the summer months along roads in Little Egg Harbor Township and past research which accounted for a large number of adults DOR (dead on road). Since 2010, we’ve been able to cut the historic roadkill rate in half, all thanks to our devoted volunteers who patrol area roads and raise awareness for them! This allows adults to grow larger and live longer lives, which helps to ensure their long term survival.

This past Monday I joined several partners to release a very special northern diamondback terrapin back into the wild. This adult female terrapin had been illegally collected and sold into the black market pet trade. Over the past couple years we have been working on a plan to get her back the wild.
Each of these partners, including Dr. John Wnek, MATES/Project Terrapin, Kelly Scott, NJ State Park Service, Brian Zarate, NJDEP Fish & Wildlife played an important role in her successful release (you can read about each of their roles in a story by Dr. Wnek below). We gathered in the parking lot of a former marina which CWF & NJDEP Fish & Wildlife converted into suitable nesting habitat for female terrapins. For all of us, I think it’s safe to say that it was bittersweet to see her swim off into the brackish water. She was home.
Over the past several years, I have worked with LBIF to help guide their efforts to provide habitat for wildlife on their property in Loveladies. We have always wanted to establish another, larger “turtle garden” for nesting female N. diamondback terrapins, since they are a common visitor during summer months. This spring we received a small grant from the Garden Club of Long Beach Island to establish a new turtle garden at LBIF. Late last month we ordered 15 tons of mason sand from a local supplier, which provides excellent nesting habitat, with small grain size and little organic matter. Myself and Jeff Ruemeli, who is the new Director of Sciences at LBIF, worked to install coir logs to hold the sand before spreading it out by hand. I followed up with planting around 30 seaside goldenrod plants at the site to help stabilize sand and provide foraging habitat for pollinators.

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.
