e from the first and a new individual will be produced, causing the plant to spread.
Humans have carried this plant around the globe. When fragments of the plant float to the surface they can be transported to new areas. Stems can become lodged among any watercraft apparatus or sports equipment that moves through the water, especially boat trailers. Milfoil can live out of water for many hours and can quickly rebound to full life once back in water.
The species is also capable of spreading through seed, although at a frequency much lower than the fragments. The current, wind and wave action transport these fragments to their new homes. Birds can also carry the plant to new locations.
There is a general agreement that Eurasian milfoil was introduced to North America, but the exact timing and location of its introduction is disputed. Details of the introduction and expansion are incomplete because Eurasian milfoil was often confused with the native North American species. It is believed that it is native to northern Europe and Asia and arrived to North America sometime between the late 1800¡s and early 1940¡s. First documented in 1942 from a pond in Washington DC, Eurasian milfoil was probably introduced to the United States around this time frame. It has now taken roots in three Canadian provinces and 45 states in the United States.
Eurasian milfoil likes to live in lakes, ponds, shallow water reservoirs and slow moving rivers and streams. The degree to which Eurasian milfoil invades a body of water varies from one location to the next. Any milfoil invasion has enough potential to seriously disrupt conditions in any body of water. The end result of these invasions is, more often than not, the decimation of the previous aquatic ecosystem.
Some of the most serious problems, short and long term effects, presented by the invasion of Eurasian milfoil are:
