Emergent aquatic plants swimming. Purple loosestrife is an example of a
problem species.

leaves)
pondweed; whorled leaf plants can uproot and
break free easily and drift with wind to clutter
shoreline; Eurasian watermilfoil is an aggressive non-
native that can affect habitat and restrict recreation.
Raking is required to remove these clutters.

rooted algae can allow worse species to come in so
don't mess with them.

other plant or algae problems
