Marsh

In physical geography, a marsh is a type of wetland area, featuring grasses, rushes, reeds[?], cattails, sedges[?], and other herbaceous plants, possibly with low-growing woody plants, in a context of shallow water, often with deeper channels.

Marshes are critically important wildlife habitat, often serving as breeding grounds for a wide variety of animal life. Estuaries are often marshes, which may be fresh-water, salt-water, or, in this case, brackish.

Some of the most important marshes are in prairie areas.

Salt-water marshes are common in areas between coastal barrier islands[?] and the inner coast.
