Species Information.

Invasive species are organisms (plants, animals and pathogens) that are not native to a particular ecosystem and whose introduction causes, or is likely to cause economic or environmental harm, or harm to human health. Due to the potential harm invasive species can cause to natural communities and systems, all New Yorkers have a stake in the issue.

Potential pathways for individuals to spread invasive species include the aquarium trade, boating, hiking, fishing, and swimming. Seeds, plant parts, or larvae attached on boots, waders, clothing, automobiles, recreational and commercial boats, paddles, life jackets, and bilge water are examples of some potential vectors that may spread invasive species.

Many invasive species are already within New York State and some are in states bordering New York. It is important to be able to identify these species and understand their impacts to respond quickly to new invaders. Below are species profiles that provide information on the appearance, biology, distribution and management information.
