EURASIAN WATERMILFOIL and White Sand Lake

(Myriophyllum spicatum)

Eurasian watermilfoil is a submersed, rooted aquatic plant native to Europe, Asia, and northern Africa. It was first reported in the United States in the 1880s and Wisconsin in the 1960s. Eurasian watermilfoil can reproduce via fragmentation, meaning a single stem fragment introduced to a waterbody could take root and establish a new population. Although it is present in almost every county in Wisconsin, it has only been verified in less than 10 percent of waterbodies statewide. While Eurasian watermilfoil can grow to nuisance levels in some waterbodies, recent studies have found that most Wisconsin lakes currently have populations at low frequencies, with relatively few lakes exhibiting very dense growth.
