It’s not surprising that Edo Potter’s favorite piece of conservation land is the next one. For decades she has been instrumental in acquiring plot after plot on her beloved Chappaquiddick for public use and enjoyment by future generations. She’s confident about the future of conservation on Martha’s Vineyard because of the health of the Island’s numerous environmental groups and their remarkable track record, both of which owe in large part to her tireless efforts.

The Martha’s Vineyard Land Bank has signed a contract to purchase 41.1 acres on Chappaquiddick, including some 900 feet of shoreline on Cape Pogue Bay.

The acquisition will be added to its existing Three Ponds Reservation, bringing the total contiguous land area to 357.7 acres.

In an announcement on Monday, the land bank said the land, at the end of Jeffers Lane, would cost $4.95 million. The sellers are Judith Self Murphy, E. Baldwin Self Jr. and Karen Self Osler.

In researching The Chappy Ferry Book, author Tom Dunlop asked his fellow Islanders what they thought was the most spectacular thing to hit the boat in its 200 years of operation

“I’ve gotten some good answers: a whale, a meteorite,” Mr. Dunlop said in an interview this week. “To a man and to a woman they stop and stare at me when I say, ‘No, an airplane hit it.’”

The Sheriff’s Meadow Foundation has purchased a new property on Chappaquiddick, the conservation foundation announced this week.

The 2.3-acre parcel sits on Manaca Hill, near Chappy Point. Viewed from the Edgartown side of the Chappaquiddick ferry, it is located on the right side of the small island, across the street from the Chappy Beach Club, and abuts the town-owned Gardner property.

Sheriff’s Meadow Executive Director Adam Moore said this week that the foundation purchased the property on Dec. 19 from Virginia Mattern for $100,000.
