An analysis of eurasian watermilfoil
Eurasian watermilfoil belongs to the watermilfoil family, haloragaceae, which has two genera in the eastern united states, myriophyllum l (10 species, the watermilfoils) and proserpinaca l (two species, the mermaid-weeds) (gleason and cronquist, 1991. The nonindigenous eurasian watermilfoil (myriophyllum spicatum l) is widely recognized as a problematic invasive plant in north america, primarily due to the rampant spread of this aquatic species throughout waterbodies of 46 states and three canadian provinces (jacono and richerson 2003 kim 2005.

Invasive species are one of the major threats to ecosystems one of these “invaders”, eurasian watermilfoil, can crowd out important native aquatic plants, decrease habitat and diversity of native species in a lake, and interfere with water-based recreation.

As a biologist with research experience on the ecology of aquatic invasive species, he thinks of eurasian watermilfoil as a potential disturbance to the native ecosystem—knowing that. Tried and true versus experimental methods for eurasian watermilfoil control: an economic analysis frances homans department of applied economics. Abstract fluridone has been used to successfully manage eurasian watermilfoil since the late 1980s however, recent documentation of hybrid watermilfoils and the resulting potential for reduced herbicide sensitivity necessitate the need for an assay to determine individual population response to fluridone a known fluridone-resistant hybrid watermilfoil population from townline lake in.

Eurasian watermilfoil is an aquatic invasive plant that has spread rapidly through freshwater lakes across the united states along with being a hazard to local ecosystems, milfoil is a nuisance to those who use lakes for recreation, and its presence has been shown to lower lakefront property values.
