(16/42) TRENTON – Due to continued pressures on northern diamondback terrapins in coastal areas of New Jersey, the Department of Environmental Protection has proposed regulations to close all harvesting of the species, Commissioner Bob Martin announced today.

“We know that this species, which holds a special place in the hearts of residents of coastal areas as well as visitors, faces many threats and has been declining in numbers for many years now,” Commissioner Martin said. “Banning all harvesting is the right thing to do to ensure future generations can continue to enjoy seeing diamondback terrapins in the wild.”

imageThe rule proposal, which appears in today’s New Jersey Register, will close the harvest season for diamondback terrapins indefinitely. The proposal, which will be open to public comment and a public hearing, follows two partial season closures ordered by Commissioner Martin after the discovery of massive harvesting of terrapins to meet market demands, primarily in Asia.

The diamondback terrapin is the only species of turtle that lives in the brackish waters of New Jersey’s coastal marshes and estuaries. It is slow to reach sexual maturity, and few of its offspring survive their first year due to predation from birds, animals and fish.

Some of its biggest challenges have also been from people hitting them with cars as they cross roads, from habitat loss, drowning in crab traps, and from people who keep them as pets.

In the past, commercial harvesting of terrapins was very limited, the season running from November 1 through March 31 and conducted by small numbers of harvesters using hand methods. But in 2013 one harvester took more than 3,500 terrapins from two locations in southern New Jersey, using a commercial crabbing dredge, and sold them to an aquaculture facility in Maryland.

A joint investigation by the DEP’s Division of Fish and Wildlife and the U.S. Fish and Wildlife Service determined that this facility used the terrapins harvested in New Jersey to raise 14,000 terrapins for sale to overseas markets.

“That incident was really a wake-up call, making us realize just how vulnerable this species had become,” said Division of Fish and Wildlife Director David Chanda. “We have plenty of observational and anecdotal evidence that the species has been in decline. We need to take a step back and get a better handle on the measures that will be needed to restore this species.”

The DEP’s Division of Fish and Wildlife has also been working with the New Jersey Marine Fisheries Council, as well as neighboring states, the U.S. Fish and Wildlife Service, and other terrapin experts to develop management strategies to enhance protection of diamondback terrapins in order to sustain the species in New Jersey.

Although the diamondback terrapin has not been listed as threatened or endangered in New Jersey, it is considered a species of special concern. As part of the state’s recovery effort, the DEP will be assessing populations, ecological data, and habitat needs as it develops management strategies.

Diamondback terrapins, so named for the diamond-shaped patterns on its shell, are more closely related to freshwater turtles than marine turtles, and spend their entire life cycle in coastal marshes. They are an important part of the ecosystem, feeding on snails that can overgraze marsh grasses, leaving them barren mudflats.

They can be found in all types of coastal habitats, including the lower Hackensack River, Newark Bay, Raritan Bay, the numerous coastal estuaries along the Atlantic seaboard such as Barnegat Bay and Great Bay, and Delaware Bay and its extensive wetland areas.
