Invasive Species Management and what it means for 2019

By David Blumer (, LEAPS, January 2019

The goal of aquatic plant management adopted by the Round Trade Lakes Improvement Association (RTLIA) for the Trade Lakes has been to control non-native aquatic plant species including curly-leaf pondweed (CLP), Eurasian watermilfoil (EWM), and purple loosestrife (PL) from damaging the health of our lakes. In late 2017 the RTLIA applied for three grants, one for each lake. To our surprise, all three of these grants were awarded by the Wisconsin Department of Natural Resources in the spring of 2018. We welcomed these grants because AIS management is very expensive including the use of chemical herbicides and physical removal. The grants support three years of CLP, EWM, and PL management on the four lakes.
