www.nyseagrant.org Plants Exotic or nonindigenous Eurasian species are plants or Water Milfoil animals that are (Myriophyllum spicatum) transported to an area outside their native European Frog-bit range where they compete (Hydrocharis morsus-ranae) with native species for food and habitat and may impact the ecosystem. These thirty Purple Loosestrife species are considered invasive (Lythrum salicaria) somewhere in New York waters. With New York’s fresh water, Water brackish, and saltwater coasts, Chestnut (Trapa natans) a species indigenous to one area may be invasive in another.
