Wetland classification

Classification of wetlands has been a problematical task, with the commonly accepted definition of what constitutes a wetland being among the major difficulties. A number of national wetland classifications exit. In 1970s, the Ramsar Convention on Wetlands of International Importance introduced a first attempt to establish an internationally acceptable wetland classification scheme. ^[1]

Ramsar classification

Main article: Ramsar Classification System for Wetland Type

The Ramsar classification of wetland types is intended as a means for fast identification of the main types of wetlands for the purposes of the Convention.^[2]

The wetlands are classified into three major classes:

• Marine/coastal wetlands
• Inland wetlands
• Human-made wetlands

These are further subdivided by the type of water: fresh / saline / brackish / alkaline; and may be further classified by the substrate type of other characteristics.

United States

Wetlands of the United States are classified according to the U.S. Fish and Wildlife Service's National Wetlands Inventory (NWI).^[3]
