In order to receive approval by the MN DNR to either chemically treat or mechanically remove nuisance aquatic invasive species from a lake, they will generally require a mapping or delineation of the boundaries of where those AIS occur in the lake. These maps are also used by herbicide applicators to determine application rates and where chemicals should be applied. Delineations are most often done for either curlyleaf pondweed or Eurasian watermilfoil. Getting approval for treatments may also require doing a native plant survey because whether or not an area is treated may depend on what other species are present with the AIS.
We have staff members trained and certified by the Minnesota Aquatic Invasive Species Research Center means you can be sure we can identify these types even though they are look-alikes to native plants.
