The wetland classification system is hierarchical, with wetlands and deepwater
habitats divided among five major systems at the broadest level.
The five systems include Marine (open ocean and associated
coastline), Estuarine (salt marshes and brackish tidal water),
Riverine (rivers, creeks, and streams), Lacustrine (lakes and deep
ponds), and Palustrine (shallow ponds, marshes, swamps, sloughs).
Systems are further subdivided into subsystems which reflect
hydrologic conditions. Below the subsystem is the class which
describes the appearance of the wetland in terms of vegetation or
substrate. Each class is further subdivided into subclasses;
vegetated subclasses are described in terms of life form and
substrate subclasses in terms of composition. The classification
system also includes modifiers to describe hydrology (water
regime), soils, water chemistry (pH, salinity), and special
modifiers relating to man's activities (e.g., impounded, partly
drained).
