New in 2016, NECWA in collaboration with Mass Audubon at Wellfleet Bay began a study on Diamondback Terrapins Malaclemys terrapin in the marshes of Wareham, Marion, Mattapoisett and Pocasset, Massachusetts.
In the spring of 2016, NECWA staff and interns walked Aucoot Beach in Marion, and Cromeset Beach in, Wareham, in search of female terrapins coming up onto the beach to nest. The Diamondback Terrapin is the only brackish-water turtle that lives in the coastal marshes of New England. NECWA has now expanded our study on nesting females which is conducted from the end of May through mid-June. In late summer and early fall, NECWA also actively documents natural and predated nests in order to better understand the survivorship of hatchings (baby terrapins) or other new recruits in these areas.
Become part of our Southcoast Terrapin Project by getting involved. If you see a Diamondback Terrapin on a beach or in the water, alive or dead, please report your sightings below.
The Diamondback Terrapin,Malaclemys terrapin, is a Threatened species in Massachusetts. In the past, this medium-sized marsh turtle was abundant in many areas of New England. However, over-harvesting of terrapins for food and the destruction of their habitats has significantly reduced their population size and overall abundance.
Like all other animals, terrestrial and aquatic, photo-identification techniques can be used to identify individuals within a population. Since each Diamondback Terrapin has unique features and markings on their skin and shell, there is no need to mark or tag individual animals. Taking photographs of specific body features allows researchers to create catalogs of individuals within a population.
