Wildlife Habitat

Troy Meadows has a biological value as wildlife habitat for ordinary, threatened and endangered species of fauna and flora, a recreational value for the people of the state of New Jersey, an open space value within a densely populated section of the state, and an economic value for the flood storage it provides.

Troy Meadows is a remnant of ancient Glacial Lake Passaic (along with the Great Swamp, Black Meadows, and Great Piece and Little Piece Meadows). It was the largest freshwater marsh in the State of New Jersey and was classified as the highest quality inland wetland in New Jersey. Unfortunately, during the past half century, its landmass has been shrinking, its landscape has been dissected, and its environmental integrity has been degraded by the construction of Interstate Route 80, Interstate Route 280, and surrounding suburban developments. Its large cattail community is being replaced by an invasive species of reed grass known as phragmites communisas a result of land disturbances, road construction, polluted storm water, silt pollution deposits, and the excessive suburban use of winter road salts.

Nonetheless, Troy Meadows remains an important habitat for a variety of birds, butterflies, mammals, reptiles and amphibians. It is located along the Atlantic flyway and serves as a staging area for migratory waterfowl.

The value of Troy Meadows is considerable as it is in the shadows of the greater New York City area. It is highly utilized by many people for educational and research purposes and for nature appreciation.
