Long Island is home of both native (aggressive) and non-native (invasive) species. Invasive species are organisms that are not native to the ecosystem under consideration and whose introduction is a constant challenge to the protection of our natural resources.
Many species have been in New York for so long that people have forgotten that they are not native. Most invasive plants were intentionally brought into a specific area for their ornamental value or ability to be used for food, fiber, or habitat restoration. Unfortunately, nobody recognized the negative impact the species would have on the environment, economy and human health until after the species were established.
Long Island lies on one of the United States’ four bird migration flyways. Among the species which stop on Long Island are the Canada goose, the Pidgeon hawk, the swift, the tree swallow, and a great number of ducks. Despite of the decline and disappearance of some species, Long Island is still home to at least 200 different birds that breed and nest here.
From shallow sandy habitats to deep boulder habitats, life for Long Island Sound’s marine life is rich in diversity. Sandy beaches are high-energy habitats that constantly change throughout the year, reflecting the effects of tides, winds, storms, and currents.
