Lawsuits and legal appeals continue to stack up in the battle over oversand vehicle trails on Chappaquiddick.

The nonprofit, which oversees miles of oversand vehicle trails on Chappaquiddick, is proposing to retire about 1,300 feet of trail along the bayside of Cape Pogue because it now regularly becomes inundated by Cape Pogue Bay. 

The third annual Bioblitz took place at Long Point Wildlife Refuge over the weekend, where citizen scientists went to work cataloguing hundreds of local species.

The Trustees of Reservations, which manages the miles of oversand vehicle trails on Chappaquiddick, must go through another layer of review, potentially bringing more scrutiny to the controversial pastime of driving trucks and SUVs out to the pristine beaches. 

A legal tug-of-war over Edgartown’s new rules for the Chappaquiddick oversand vehicle trails has broken out, with the nonprofit that manages the coastline and a citizen’s group both filing appeals with the state this week. 

The Edgartown conservation commission Wednesday voted to allow no more than 200 vehicles at a time on the Trustees’ Leland and Wasque parcels, and no more than 30 on the Cape Pogue trails.

This week, The Trustees of Reservations, the nonprofit that manages the 16 miles of Chappy trails, publicly objected to proposed regulations from the Edgartown conservation commission, saying the rules are not aligned with state environment law and instead were formed with local politics in mind.

The natural splendor of the beaches on Chappaquiddick attracts swimmers, hikers, anglers, sunbathers, birdwatchers and sunset — or sunrise — watchers.

The draft regulations proposed no more than 200 oversand vehicles at a time on the Leland and Wasque properties, and no more than 30 on the Cape Pogue trails.

Joseph McLaughlin joined the organization in late February after decades as director of properties at the Norman Bird Sanctuary in Rhode Island, according to the Trustees.
