Wetland class definition

Wetland class means the general appearance of the wetland based on the dominant vegetative life form or the physiography and composition of the substrate. The uppermost layer of vegetation that possesses an aerial coverage of 30 percent or greater of the wetland constitutes a wetland class. Multiple classes can exist in a single wetland. Types of wetland classes include forest, scrub/shrub, emergent, and open water.

Wetland class means a description of vegetation habitat based on the predominant life forms that occupy a particular layer of vegetation and possess an aerial coverage of thirty percent or greater of the entire wetland. The basis for these descriptive classes is derived from the Wetlands Taxonomic Classification System of the United States Fish and Wildlife Service (Cowardin et al., 1978).

Wetland class means the U.S. Fish and Wildlife Service wetland classification scheme using a hierarchy of systems, subsystems, classes and subclasses to describe wetland types (refer to USFWS, December 1979, Classification of Wetlands and Deepwater Habitats of the United States for a complete explanation of the wetland classification scheme). Eleven class names are used to describe wetland and deepwater habitat types. These include: forested wetland, scrub-shrub wetland, emergent wetland, moss-lichen wetland, unconsolidated shore, aquatic bed, unconsolidated bottom, rock bottom, rocky shore, streambed, and reef.
