EGLE permits the chemical control of both native and non-native aquatic vegetation. Native vegetation may be treated for control of nuisance conditions that impedes recreational use of the site. Control of native vegetation is typically restricted in size and location to areas with the highest recreational usage (along developed shoreline). Treatment of native vegetation is limited in this manner to provide habitat protection for native plants and animals that live in the lake. Treatment of non-native vegetation may be permitted anywhere in the waterbody, provided that it can be conducted in a selective manner (through selection of the herbicide active ingredient, dosage, seasonal timing, treatment frequency, etc.) and with the required bottomland owner permissions and treatment map delineations. More expansive treatment of non-native species is allowed in order to counteract the spread of invasive species and promote the return of native plants to the system.
