LONG POND GREEBELT
Southampton Trails Preservation Society
The Long Pond Greenbelt encompasses a magnificent 1,100-acre expanse of interconnected ponds, woods, and
wetlands that stretches nine miles from Ligonee Brook and Otter Pond in Sag Harbor south to Sagg Pond and the
Atlantic Ocean shore in Sagaponack. Spectacular for its wealth of rare plants, animals, and ecological communities,
the Greenbelt is widely recognized as one of the most ecologically significant areas in all of New York State.
A splendid feature of the Greenbelt is its magnificent collection of coastal plain pond and pondshore communities, 13 of
which occur in this system. Both statewide and globally, these environments are considered very rare and vulnerable to
extinction. They also harbor the highest concentration of rare plants and animals in New York. New York Natural
Heritage Program has confirmed the presence of more than 30 rare species of plants and animals.
This unique area encompasses a chain of freshwater coastal plain ponds, wetlands, and vernal ponds as well as Sagg
Pond (a coastal salt pond), the tidal waters of Otter Pond, and the lower reaches of Ligonee Brook. The area was
created some 21,000 years ago by glacial advance and retreat creating the east-west trending moraines on Long Island
(the Harbor Hills and Ronkonkoma Moraines). The large-scale subsurface ice formation and subsequent collapse due
to melting caused ponds to form north of the morainal deposits. These ponds became south-flowing streams which
eventually eroded the moraine to form the north-south trending channel between Sag Harbor and Sagaponack.
Repeated seasonal meltwater streams created the present remarkable landscape.
Extravagantly rich in plant and animal life, the Greenbelt forms one of the most biologically diverse eco-systems in the
Town. More than 100 different bird species have been found in the area alone, many of which depend directly or
indirectly on the wetland complexes found in this corridor.
Efforts to preserve the Long Pond Greenbelt began in earnest in 1969. The Greenbelt was officially designated as a
high priority for preservation in 1985 through the Town’s adoption of the Long Pond Greenbelt Action Plan. The town’s
Comprehensive Plan Update and 1995-96 Open Space and Greenbelt Acquisition Programs have likewise noted this
areas significance, and identified it as one of the highest priorities for the Town. As a result of these initiatives, more
than 500 acres have already been preserved.
The Old Railroad Spur was an actual railway connection from the Bridgehampton Train Station to Sag Harbor’s Long
Wharf between 1870 and 1939. A 1400-foot connection was constructed between the spur and the Round Pond ice
house to facilitate shipping ice to New York City. The track was pulled up to supply steel during World War II.
Native American habitation dates back possibly 6,000 years and centered on freshwater ponds. The first European
settlers arrived on the South Fork in the late 1640s. Many colonial roads followed the long used trails of the Native
Americans. The present-day trails in the Long Pond Greenbelt are known colonial road-beds.
In the late 1600’s to the mid 1800’s, grist mills operated in the area of Sagg Swamp and Sagg Pond.
An ice house was run from Round Pond for approximately 70 years in the mid 1800s, and a dam was built in the late
1800s at the north end of Long Pond to provide public water for Sag Harbor.
In the late 1800s a mile long trench was dug between Crooked Pond, Deer Drink Pond, Long Pond and Otter Pond to
increase the flow of water needed to operate a mill on Otter Pond.
From the early 1960s through the 1990s, Old Hickory Farm on Haines Path offered horseback riding by the hour through
the beautiful trails in the Long Pond Greenbelt.
Coastal plain ponds are characterized by nutrient poor, acidic water and a gently sloping shore. Most coastal plain
ponds are not stream-fed, but are directly connected to groundwater. Pond water levels rise and fall with the water
table, reflecting seasonal and annual rainfall patterns. As a result, a unique community of plants grow along the pond
shores. Periods of both low and high water levels are essential for their survival.
The Long Pond Greenbelt was created 21,000 years ago by large scale, subsurface ice formation and subsequent
melting. Geologist William Neiter describes it as a rare, near-glacial relic, the likes of which are found only in the tundra
regions of Russia.

head south past the tennis courts between the athletic field and the railroad bed to the on the Crooked Pond Trail. During a
Truman Capote by his partner. The return leg of the hike passes a third pond called Little Long Pond. There is a boat ramp
off of Widow Gavitts Road where you can launch a kayak or canoe onto Long Pond.
Kayakers and local hikers love the seclusion and beauty found here. There are other ways to enter the Long Pond Path then
between Deer Drink and Long Pond, then onward towards Sagg Road and the Northwest Path.
