Selected images for Eurasian watermilfoil (Myriophyllum spicatum )
Eurasian watermilfoil is a submersed aquatic plant that invades lakes, ponds, and other aquatic environments throughout the United States. The plants are rooted and the stems grow up to the water surface, usually reaching 3 to 10 ft. (0.9-3 m) in length, however they can be as much as 30 ft. (9.1 m) long. Eurasian watermilfoil forms dense mats of bright green, finely dissected, whorled leaves. The delicate leaflets give this plant a feathery appearance. Eurasian watermilfoil requires stagnant to slowly moving water and can tolerate brackish conditions. Once established the dense mats of leaves restrict light availability, leading to a decline in the diversity and abundance of native macrophytes. In addition, Eurasian watermilfoil displaces the native species of watermilfoil and reduces habitats for fish spawning and feeding. Eurasian watermilfoil is native to Europe, Asia, and northern Africa. It was accidentally introduced into the United States sometime between the late 1800s and 1940s.
