Marshes form where water is very close to, or above, the ground surface for part or most of the year. This results in a waterlogged environment that stays soggy even if there are no pools of standing water. Marshes are either features in their own right, or zones along the margin of a lake or a river's edge. In intertidal areas along the coast, salt marshes sometimes occur. Surprisingly, these are enormously biologically productive.
