Marshes are defined as wetlands that are frequently or continually inundated with water. These areas are characterized by emergent soft-stemmed vegetation that is adapted to saturated soil conditions. There are many different kinds of marshes, ranging from the prairie potholes to the Everglades, coastal to inland, freshwater to saltwater. All types receive most of their water from surface sources, and many marshes are also fed by groundwater. Nutrients are plentiful and the pH is usually neutral, which leads to an abundance of plant and animal life.
