Floating leaf pondweed provides
valuable grazing for ducks and geese late in the growing season.
Muskrat, beaver, deer and moose will all consume portions of
floating leave pondweed. Because of the shade and foraging
opportunities, it produces floating leaf pondweed in considered
good fish habitat.
Dense populations of plants
reduce the water temperature and oxygen concentrations when plants
die in late summer. Floating Leaf Pondweed may form dense
mats blocking sunlight for other submersed vegetation along with
interfering with fishing, boating and swimming.
Leaves both floating and submersed.
Submersed leaves are long and narrow. Floating leaves are oblong
and slightly heart-shaped at base. Parallel leaf veins are evident.
Stems occasionally branched. Leaves are alternately arranged on
stem. Solid, tightly packed spike of nutlets at tip of weed rises
above water surface.
