Aquatic Invasive Species

Every species has a natural range that is governed by biological, chemical, and physical barriers. As development occurs and as people move and travel, they often bring species from other areas with them. These species – both plants and animals – are known as exotic and non-native species because they are introduced to an area outside of their native range. When these exotic species survive and thrive in the new location, reproducing and competing with native organisms, they are known as invasive species. Their presence can cause environmental harm to the local ecosystem, and negatively impact local economies. In marine, estuarine, river, and lake ecosystems, these species are known as aquatic invasive species.
