Eurasian water-milfoil is an invasive aquatic plant native to Europe, Asia and northern Africa. Introduced to North Americain the 19th century, it is now one of the most widely distributed invasive aquatic plants on the continent. It may have been introduced through the aquarium trade or the ballast water of ships.
Eurasian water-milfoil prefers shallow water one to three metres deep, but can root in up to 10 metres of water. A fast-growing perennial, it forms dense underwater mats that shade other aquatic plants. When large stands begin to die off in the fall, the decaying plants can reduce oxygen levels in the water.
