The Sherwood-Jayne Farm is private preserve owned and managed by the Society for the Preservation of Long Island Antiquities (SPLIA). The Seatuck Environmental Association operates a natural history education program on the property through a partnership with SPLIA. The programming includes not only straightforward nature programs, but also programs that explore how early settlers lived with and relied upon the natural landscape.
The Sherwood-Jayne Farm is the 18th century Jayne family homestead, which was acquired in 1908 by SPLIA founder Howard Sherwood, who filled the house and outbuildings with a varied collection of furniture and objects. The immediate acreage around the Sherwood-Jayne house is a bucolic setting that retains its 19th Century agrarian context, including grazing sheep, pastures and orchard. The majority of the 80-acre property, however (including a portion owned by Suffolk County) is a natural and ecologically rich landscape featuring mature upland forests and the varied topography typical of the North Shore. Several miles of hiking trails have recently been established to make more of the property's beauty and wildife accessble to the public.
