Eurasian Water Milfoil
Eurasian water-milfoil is an invasive plant that is native to Asia, Europe and Northern Africa. Since it’s introduction to North America in the 19th century, it has now become one of the most widespread invasive aquatic plants on the continent. This plant is spread easily from boats and other recreational activities, as broken plant fragments readily root and infest new areas.
Eurasian water-milfoil is identified by its feather like leaves that arranged in whorls around the plant stem. In July and August, small red flowers are visible just above the water’s surface.
Effects on our Ecosystems
The impact of Eurasian water-milfoil on our waterways can be severe. It can cause loss of native plant species through competition; reduced oxygen levels in the water leading to fish death; thick mats of plants hindering recreation activities such as swimming and boating; and dense stands leading to water stagnation and increased mosquitoes.
