Predicting the invasion process of European frogbit (Hydrocharis morsus-ranae) and a survey of possible biological control organisms in the Great Lakes region

European frogbit, an invasive floating plant, has been spreading   rapidly from Canada to the Great Lakes region in the U.S. It may be   an imminent threat to further areas of the Great Lakes Basin,   including areas in New York State, and likely to have major impacts   on these surrounding natural ecosystems. Knowledge of its invasive   ability will be crucial to predict the potential extent of future   distributions and by extension the resulting ecosystem disruption   and economic loss. Therefore, this project will investigate the   major environmental factors contributing to the rapid expansion of   this plant, and explore possible biological control agents to manage   its current population. This study is important to the health of the   Great Lakes because current expansion of European frogbit is rapid   and may lead to ecosystem disruptions in nearshore areas and   protected bays.    (European frogbit); (Hydrocharis morsus-ranae); (AIS); (aquatic   invasive species); (New York); (invasive plant); (invasive plants)
