Welcome to the
New York Invasive Species Clearinghouse
The New York Invasive Species Information Website - NYIS.INFO and its host, the New York Invasive Species Clearinghouse, [jointly referred to as NYIS.INFO] were founded in October 2008. NYIS.INFO is funded with New York State Environmental Protection Fund resources through a contract with the New York State Department of Environmental Conservation. NYIS.INFO was established in response to Recommendation 5 of the November 2005 report of the New York State Invasive Species Task Force to the Governor and Legislature. The Task Force recommended that the State should integrate invasive species databases and information clearinghouses. This resulted in the creation of the Clearinghouse. The Clearinghouse is authorized and overseen by the New York State Invasive Species Council, which is co-chaired by the New York State Departments of Environmental Conservation and Agriculture and Markets. For more information on who we are, please refer to our About page. More information on New York State's invasive species program can be found on our State and Federal Activities tab under NYS Invasive Species Policies.

The European water chestnut (scientific name Trapa natans; common names: horned water chestnut, water caltrop), an invasive aquatic plant released inadvertently into waters of the Northeast in the late 1800s, is slowly but inexorably spreading throughout New York State, clogging waterways, lakes and ponds and altering aquatic habitats.
Water chestnut is native to Europe, Asia and Africa. In its native habitat, the plant is kept in check by native insect parasites. These insects are not present in North America and the plant, once released into the wild, is free to reproduce rapidly. Water chestnut colonizes areas of freshwater lakes and ponds and slow-moving streams and rivers where it forms dense mats of floating vegetation, causing problems for boaters and swimmers and negatively impacting aquatic ecosystem functioning.
