Elodea: an emerging submerged weed in Victoria

摘要

Elodea (Elodea canadensis Michx.) is a perennial aquatic plant that grows totally submerged. It is a native of North America and was introduced to Australia and other parts of the world as an aquarium plant. Large infestations of elodea were discovered in a wetland at Endeavour Hills in Victoria recently. Elodea is actively expanding its range in Victoria and is likely to continue to do so within the system it has already invaded. Every attempt should be made to limit its movement between water bodies.
