Marsh:Marshes feature standing
water from less than an inch to several feet deep. The amount
of water can fluctuate seasonally or from year to year. Marshes
might generally be called “flooded grasslands.” They are dominated
by soft-stemmed emergent plants such as cattails, grasses,
sedges and rushes. In deeper water are found lily pads and
submerged plants such as milfoil and pondweed. Marshes are
critical for many fish species that live and/or breed there.
Marshes also offer primary breeding and feeding habitat for
water birds and some song birds, as well as numerous amphibian,
reptile and mammal species.
Shoreline: The Great Lakes shoreline features nearly 11,000 miles of diverse habitat-everything from sheer, rocky cliffs to active dune systems to marshy freshwater estuaries. In general, these shoreline areas are extremely dynamic, strongly influenced by weather and water level changes, and they support an incredible variety of plants and animals.
