Manor St. George or St. George's Manor was a large tract of land purchased by William "Tangier" Smith in the 17th century on Long Island, in central Suffolk County, New York. Parts of the original parcel, which was approximately 64,000 acres (260 km2) of land, are preserved in bits and pieces: 127 acres (0.51 km2) and the main house and buildings are called the Manor of St. George and located in Shirley; 35 acres (0.14 km2) and another house are called the Longwood Estate and located in Ridge; and 35 acres (0.14 km2) became part of the William Floyd Estate. The Museum Manor of St. George is in a testamentary trust set up underneath the last will and testament of the late Eugenie A.T. Smith. The management of the manor rest with the trustees. The purpose of the private trust is to promote the Smith family history dating back to 1683. The Longwood Estate (sometimes called the Smith Estate) is maintained by the Town of Brookhaven, and the Floyd Estate is maintained by the National Park Service. The hamlet of Manorville also derives its name from Manor St. George.Manor St. George originally stretched from Carmans River (then called the Connecticut River) in the west to the edge of Southampton Town in the east, and from the Atlantic Ocean in the south to around present-day New York State Route 25 in the north.

The Wertheim National Wildlife Refuge is located on the south shore of Long Island and is one of the undeveloped estuary systems on Long Island. In 1947, Maurice Wertheim donated 2,000 acres (8.1 km2) on eastern Long Island to the United States government; the donated land subsequently became the Wertheim National Wildlife Refuge. The refuge's purpose is to protect the Carmans River Estuary for migratory birds. Wertheim hosts a variety of habitats including oak-pine woodlands, grasslands, and fresh, brackish and salt water wetlands. These habitats attract and support many types of wildlife including white-tailed deer, osprey, muskrat, fox, turtles, frogs and fish. The refuge also serves as a haven for waterfowl, shorebirds, raptors, and songbirds. In 2012 the Long Island National Wildlife Refuge Complex opened a new visitor center and headquarters facility in the Wertheim National Wildlife Refuge. The building includes an interactive exhibit hall, environmental education classroom and administrative offices.

The Poospatuck Reservation is a Native American reservation of the Unkechaugi band in the community of Mastic, Suffolk County, New York, United States. It is one of two Native American reservations in Suffolk County, the other being the Shinnecock Reservation. The population was 436 at the 2020 census. The Unkechaugi are descendants of the Quiripi-speaking Native Americans, who occupied much of southern New England and central Long Island at the time of European encounter in the colonial era. Historically they spoke an Algonquian language. They have retained a community; the reservation is the smallest in New York State. The current 55 acre reservation was originally set aside for the Unkechaugs as a 175-acre plot by William "Tangier" Smith after he purchased large tracts of land from Unkechaug John Mayhew in 1691. It is located in Mastic on the north side of Poospatuck Creek, on the east side of Poospatuck Lane, and south of Eleanor Avenue. Poospatuck is situated in the southeast corner of Suffolk County's present-day Town of Brookhaven; and is the township's sole Indian reservation. On account of the innumerable tobacco shops, the reservation is known synecdochally as "Mastic Boges" by those in neighboring towns. It is about 70 miles or 1½ hours east of New York City. The reservation and its people are recognized as Native American by the state of New York but it has not received federal recognition from the US Bureau of Indian Affairs. However, the Unkechaug established that it met the criteria of a Tribe set out in the Supreme Court case Montoya v. United States, 180 U.S. 261, 266 (1901). The Unkechaug proved beyond a preponderance of the evidence that they met the criteria of a common law definition of a tribe consisting of the following: 1. A body of Indians of the same or similar race; 2. United in a community under one leadership or government; 3. Inhabiting a particular though sometimes ill-defined territory. Federal District Judge Kiyo Matsomoto held that the Unkechaug satisfied all 3 Montoya criteria thereby entitling the Unkechaug to Sovereign Immunity from lawsuits because they are a federal Tribe under federal common law.
