After intensive testing throughout the weekend, Lambert’s Cove Beach and Long Point Wildlife Refuge Beach in West Tisbury remained closed to swimming on Monday afternoon due elevated levels of enterococcus. All beaches in Oak Bluffs had opened by Saturday afternoon, except for Madeiros Cove, which remains closed.

Growing up on a ranch in Wyoming, Barbara Erickson received an early education in the importance of open space.

“You get an appreciation for nature that sticks with you,” the newly-appointed president of The Trustees of Reservations said on Friday during a sun-splashed walk through Long Point Reservation in West Tisbury. “Then you come to a place like Massachusetts which is 10 times smaller and I really think it’s a call to action to preserve as much as we can. I think the Trustees has been a trailblazer in that effort.”
