Exotic Invasive Species
Fire Island National Seashore is a complex park with a number of historic and modern structures, landscapes, and natural areas, including wilderness and dynamic coastal dunes. But an assortment of urban and rural pests, such as exotic invasive plants and animals, often find their way into the park through neighboring non-federal lands. Some species were established before the park was designated.
Invasive plants and animals pose a severe long-term threat to biodiversity and ecosystem stability as they crowd out native species. Some exotic species also pose health risks and adversely affect outdoor recreation and fisheries. Sometimes, native species become "pests" when they find food and shelter or take up residence under unnatural circumstances.
