Aquatic invasive plants include exotic, nonnative, or new to the area plants and algae that grow partially or entirely submerged in water. This includes plants that are rooted in the ground with part or all of the plant underwater, as well as plants that float freely in water. They pose a significant threat to our aquatic resources, water supplies, or water infrastructure. With no natural enemies to keep their population in check and their ability to outcompete Nebraska’s native species for food and other resources, aquatic invasive plants can become widespread in a waterbody quickly.
Four categories have been established for designated aquatic invasive plants that are found in Nebraska:
Category 1: Potential Aquatic Invasive Species
Category 1: Potential Aquatic Invasive Species are those species that have not yet been sampled in Nebraska and are considered a high threat. Those organisms include:
Category 2: Priority Aquatic Invasive Species
Category 2: Priority Aquatic Invasive Species are those species that are currently present in Nebraska but with limited distribution. They are considered highly unwanted species and all efforts should be taken to prevent the expansion of their populations. Those species include:
Category 3: Established Aquatic Invasive Species
Category 3: Established Aquatic Invasive Species are those species that are well established in Nebraska and total elimination is impossible. Protocols established in Nebraska Administrative Code Title 163, Chapter 2, sub-sections 012.02 to 012.04 do not apply to the species on this list, which includes:
Category 4: Aquatic Invasive Species Listed as Noxious in Nebraska
Category 4: Aquatic Invasive Species Listed as Noxious in Nebraska are regulated by the Nebraska Department of Agriculture as noxious plant species. Those species include:
