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.
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.

Northern diamondback terrapins are a coast hugging, saltmarsh living, shellfish eating, aquatic turtle. Their ultimate survival depends on the ability of adult females to safely access nesting areas during summer months. Since 2010 CWF has worked to document and reduce roadkills of terrapins on roads in southern Ocean and northern Atlantic Counties.
