Forty-four acres of forests, wetlands and fields along Bogtown Road were generously donated to NSOLF by long time North Salem resident Stephen Stempler in 2006. The Stempler Preserve features forests, beautiful rock outcroppings, mature oak stands, a stream and is home to mink, otter, coyotes, and bobcats. This property borders NSOLF's 34-acre Hawthorne Preserve.
Stempler Preserve is open to the public. A trail is currently under construction.
