WESTPORT — You can call it a walk into natural history, or just a warm-weather stroll. Either way, visitors will want to join the Westport Historical Society next Saturday, June 18, at 3 p.m. for a unique tour of the Haskins Preserve.

Unknown to most Westport residents, the 22-acre preserve, owned by the Aspetuck Land Trust, is at the end of Green Acre Lane off Compo Road South.

“A lot of people have never been to it,” said Susan Gold, executive director of the historical society, who will also lead a Qi Gong session prior to the event, a “Tree Walk at the Haskins Preserve.”

“We’ve done these tree walks before,” Gold said, in several locations, including Winslow Park. “They’re very popular.”

Ben Sykes, an arborist with the Care of Trees in Norwalk, will lead the walk, focusing on the range of unique trees inhabiting the large property, including a Chinese catalpa, Japanese hinoki cypress, and a dawn redwood.

“With so much new development in Westport,” Sykes said, “and homes being torn down and the land cleared, we don’t get to appreciate mature trees.”

The preserve was originally the estate of Caryl and Edna Haskins, two scientists who brought back a range of unique specimens from around the world that they planted there, ultimately willing the land to the trust.

Reservations are suggested; Donation is $10. For details, call 203-222-1424 or visit westporthistory.org.
