for wildlife and shouldn't be controlled except in

, Growth habits: rooted plants with all of their growth
occurring below the water line (i.e. pondweeds)
Dispersal:
Pondweeds - extensive root systems and runners,
new growth sprouts from roots, runners and seeds;
some have floating leaves and some submerged
leaves that are attached to center stem in alternate
arrangement.
Whorled leaves - 3 or more leaves attached at one
point on the main stem i.e. coontail, water milfoil,
and elodea are most common.

Aquatic Plants
Whorled leaves - if uprooted they break free, drift
with wind and clutter shoreline; must hand rake to
remove them. Cutting plants without raking can
produce nuisance situation. Motorboats can
aggravate situation and cause nuisance infestation.
Third type of submergent plant: water celery, tape
grass, and eelgrass. Grows in clear water to a depth
of 15ft. has long, green, ribbon-like leaves extending
from the base of the plant. Should be left alone
because it's a food source for waterfowl.
