Eurasian watermilfoil is one of the most aggressive and problematic aquatic weeds found in ponds and lakes. It has reddish stems with delicate, fan-shaped leaves arranged in whorls around the stem. This invasive plant spreads rapidly, primarily through fragmentation, where small pieces break off and establish new growth. Once introduced, Eurasian watermilfoil can form dense underwater mats that outcompete native vegetation, reduce biodiversity, and interfere with recreational activities such as boating, fishing, and swimming. Early detection and consistent management are essential to prevent its spread and maintain a balanced aquatic ecosystem.
