DNREC Seeks Volunteers to Help Nesting Diamondback Terrapins
DOVER, Del.- DNREC’s Division of Fish & Wildlife is seeking volunteers to ensure diamondback terrapins are successful in their journey toward reproduction at one of many places they come ashore to nest: along the Delaware bayshore’s Port Mahon Road near Little Creek.
Fish & Wildlife staff will offer volunteer training beginning at 5:30 p.m. Thursday, May 18 on Port Mahon Road. In the event of inclement weather, training may be rescheduled.
Diamondback terrapins live in and along Delaware’s bayshore, inland bays and tidal creeks. They spend their lives in brackish waters, but every spring female terrapins leave the water to lay eggs.
At the peak of nesting season, hundreds of terrapin heads can be seen in the water off Port Mahon as they approach the shoreline. Then, when the tides, temperature and humidity are right, the female terrapins come ashore to lay their eggs.
Fish & Wildlife officials said Port Mahon Road borders the bay in some locations and is often flooded with water and debris during high tides and storm events. In 2015, large rocks were placed along sections of Port Mahon Road to protect it from erosion and debris accumulation. Officials said however, that these rocks can trap terrapins as they leave the water to nest and when making their way back to the bay after laying eggs. Terrapins blocked by the rocks also spend more time in the road where they risk being hit by cars.
To help the terrapins cross the road safely, the state’s Department of Transportation has constructed two “experimental terrapin tunnels” – wide concrete pipes that run under the rocks to provide the terrapins with safe passage between the bay and their nesting areas. While similar devices have been successful in other locations, this will be the first nesting season with these structures in place at Port Mahon, so the Division of Fish & Wildlife is seeking volunteers to monitor terrapins and their use of the tunnels, and to assist them as needed.
“With only two test tunnels in place, many terrapins may not be close enough to use one, so volunteers are needed to help the terrapins navigate into the tunnels or around the rocks,” said Wildlife Biologist Holly Niederriter, Division of Fish & Wildlife. “If terrapin passage through the tunnels appears to be successful, additional tunnels may be added along the road in the future.”
