Common Invasives 

Long Island Native and Invasive Species

Long Island is home to many types of plants and animals all competing for food and space to grow. Different species are classified into different types depending on their impact on the environment. 


Native Species are species that once established, thrive in the environment they are naturally adapted to. 


Invasive Species are capable of rapid spread into relativly undisturbed natural communities. Once established invasive species begin outcompeting native plants, damaging soil and causing adverse ecological impacts. 

Vernal Pools

The Muttontown Preserve is heavily influenced by early glacial activity that formed the topography of Long Island. Rocky soils, uneven and glacially carved depressions. Vernal pools are bodies of freshwater leftover from storm water runoff or collections  

Muttontown Preserve History

Muttontown Preserve is 568 acres of land and is the largest preserve owned by Nassau County. It was formerly four different estates, the Moore Estate, Hudson Estate, Winthrop Estate and Hammand vacation home.


Mr. and Mrs. Benjamin Moore had their estate built in the 1920s. Mr. Moore named the estate Chelsea, referencing the section of New York City where his family lived for many generations. Mr. Moore died in 1938. His wife, Alexandra donated the land to Nassau County in 1966 to start a preserve. The nature center was built in 1970. When Mrs. Moore died in 1983, Nassau County acquired all of the Chelsea Estate.


Charles Hudson, a Wall Street mogul and steel tycoon, owned 240 acres of the Knollwood Estate which has been built in 1907. He died in 1921 and his estate went through several owners until 1951 when King Zog of Albania purchased the property. King Zog wanted to establish a kingdom for himself and fellow exiled countrymen but his plan failed and they never lived at Knollwood. The servants moved away and the house became vacant, leaving it and its rumored hidden treasures to be vandalized. In 1955, Landsdell Christie bought Knolwood in 1955 and demolished the vandalized home. In 1968, the county purchased the property. The only remaining pieces of the Hudson Estate are gazebos, a concrete walled garden and the main gate at the corner of Route 106 and Muttontown Road.


Mr. Cristie also purchased the Winthrop Estate. Bronson Winthrop purchased the John Duyea Farm in 1903 and built his mansion on the property, now known as Nassau Hall. Christie created a pinetum between 1956-1960 but sold his property to Nassau county in 1968.


Earlier, Captain Paul Hammond purchased land from Mr. Winthrop. This 20 acre section of Muttontown south was part of the Duryea Farm. It included a house build during revolutionary times known as the "Barn swallow". Captain Hammond's family used this as a vacation home until 1974. At that time, Nassau County acquired "Barnswallow" from Mrs. Hammond.


After acquiring the land, Nassau County developed its largest preserve. In 2006, Long Island Press named the Muttontown Preserve "Best Nature Walk" on Long Island.

Town of Muttontown History

Muttontown is an incorporated village in the Town of Oyster Bay located in Nassau County, New York. The 3852.8-acre town is just north of Jericho and to the south of Oyster Bay. The towns history includes many pastures of sheep farms. As far back as the 1600s, sheep were raised for the production of their meat and wool. The meat from sheep, or mutton, is how the town became Muttontown sometime after 1750.

Nassau Parks Conservancy Hall

Delano & Aldrich, the prominent architect of the ‘20s made his first commission in this area. His first commission is the Christie House on Muttontown Rd whose exterior wall was modeled after Mount Vernon, the home of our first president, George Washington. This mansion is now called Nassau Hall owned by Nassau County. Nassau Hall was built by Delano & Aldrich for the Winthrop family and was known originally as the Egerton L. Winthrop Jr. House or Muttontown Meadows. The estate was purchased by Lansdell Christie in 1950 and hence called the Christie House. His widow, Helen Christie sold the house and its 183 acres to Nassau County in 1969. It is now the home of Nassau Parks Conservancy. The grounds at Nassau Hall have one of the biggest collections of pine trees in all of Long Island, NY.
