There are nearly three dozen AIS — about an equal number of plants, fishes, invertebrates, and microbes — that MAISRC currently considers high-risk for Minnesota and in need of research into their detection, prevention and control. Learn more about these priority species by clicking below.

Aquatic species are adapted to habitats that are regularly or permanently inundated, including lakes, rivers, and many kinds of wetlands. Invasive species are those that when moving into a new locale tend to spread rapidly, outcompete resident species, and cause — or likely cause — ecological or economic harm or harm to human health.
