Invasive species are non-native plants and animals that reproduce and spread quickly, compete with native species for food, degrade habitat, and ultimately cause ecological and economic damages. The many established invasive species have caused great damage in the Great Lakes. Physical barriers such as land masses, currents, and large gaps in suitable habitat (like deep ocean basins that separate shallow reefs), limit movement of aquatic species. Non-native Cattail Cattail Scientific name: Typha angustifolia Aquatic Invasive Species pose an ever- growing danger to the health of our Nation's ecosystems. Between 1918 and 1981, over 400 million common barberry shrubs were destroyed. More than 180 non-native species have entered the Great Lakes, and a new species is discovered every 28 weeks on average. Invasive species are perhaps the greatest stressor currently facing the Great Lakes aquatic ecosystem. Some of the common plant species that are invasive in the Great Lakes include purple loosestrife, curly pondweed, reed canary grass, common reed ( Phragmites ), cattail, Japanese knotweed and Eurasian watermilfoil. It is used to provide stability and maneuverability during a voyage when ships are not carrying cargo, not carrying heavy enough cargo, or when more stability is required due to rough seas. Aquatic Invasive Species Efforts. Audubon Great Lakes is also working with partners in Michigan to remove invasive Common Reed ( Phragmites australis) later this fall. With industry-driven best management practices, no new invasive species have been introduced into the Great Lakes-St. Lawrence Seaway System through the uptake and discharge of ships' ballast waters since 2006. The Great Lakes and St. Lawrence Governors and Premiers have identified the "least wanted" aquatic invasive species (AIS) that present an imminent threat to the Great Lakes-St. Lawrence River region. Sea lamprey, alewife, dreissenid mussels, round gobies, and the spiny water flea are all examples of invasive species that have affected or are affecting Great Lakes fisheries.

Parts of the Great Lakes, including nutrient-rich bays, tributaries, and other near-shore areas, would offer invasive carp an abundant supply of their preferred food, plankton. Invasive species cause harm when they out-compete native species by reproducing and spreading rapidly in areas where they have no natural predators and change the balance of the ecosystems we rely on.

Aquatic invasive species is a wicked problem, not due to unclear definitions on what the problem is exactly but due to the impossible task of completely eradicating (or solving) an invasive species in a lake or body of water. Invasive species: a long-term assessment of the the zebra mussel invasion in the inland lakes of southern Michigan (with MSU); Land use and climate change: a study of how climate-affected environmental factors constrain the structure and function of the Great Lakes "food web," with a look toward predicting how climate change will impact . The ones with arguably the most devastating impact are much less frightful-looking than sea lampreys: the tiny zebra and quagga mussels, which are believed to have entered the lakes in the late 1980s in ballast water from ocean-going ships. The Great Lakes are national treasures. Invasive species damage . In that water was the Eurasian zebra mussel, which is now a threat to 140 native mussel species. Over a decade ago, a Caspian Sea tanker released its ballast water into the Great Lakes.
