Classification of Wetland and Deepwater Habitats(lO) 



Compared to Other Procedures 



(at the Class and Subclass Levels) 



Class, Subclass (10) 



The class is the general appearance of the habitat in terms of 

 either the dominant life form of the vegetation or the physiography 

 and composition of the substrate. Subclasses are used for finer 

 differentiation. 



Emergent 



Characterized by erect, rooted, herbaceous hydrophytes, exclud- 

 ing mosses and lichens (10). Named marshland in (2). 



Emergent/saturated/organic soil is equivalent to fen (3, 10). In (3), 

 this includes: Atlantic ribbed fen, basin fen, channel fen, collapse 

 scar fen, feather fen, floating fen, horizontal fen, ladder fen, 

 lowland polygon fen, net fen, northern ribbed fen, palsa fen, shore 

 fen, slope fen, snowpatch fen, spring fen, and stream fen. 



An emergent/saturated/Palustrine area in (10) would be called 

 herbaceous in (8). 



Emergent/saturated, fresh water/mineral soil is equivalent to 

 marsh, fresh water in (8), or in (3), a subclass could be tidal fresh 

 water marsh, floodplain marsh, stream marsh, channel marsh, 

 active delta marsh, inactive delta marsh, terminal basin marsh, 

 shallow basin marsh, kettle marsh, seepage track marsh, and 

 shore marsh. 



Moss-Lichen 



Aquatic Bed 



Emergent/saturatedAnixosaline/mineral soil is equivalent to marsh, 

 saline water in (8) or estuarine high marsh, estuarine low marsh, 

 coastal high marsh, and coastal low marsh in (3). 



A saturated regime where mosses or lichens cover substrate other 

 than rock and where emergents, shrubs, or trees make up less 

 than 30 percent oftheareal cover (10). Called a bog in (8). In (3) 

 this includes: Atlantic plateau bog,basin bog, blanket bog, collapse 

 scar bog, domed bog, flat bog, floating bog, lowland polygon bog, 

 mound bog, northern plateau bog, palsa bog, peat mound bog, 

 peat plateau bog, polygonal peat plateau bog, shore bog, slope 

 bog, string bog, or veneer bog. 



Wetlands and deepwater habitats dominated by plants that grow 

 principally on or below the surface of the water for most of the 

 growing season (10). Called floating, rooted submerged, ix)oted 

 floating, rooted emergent in (8). Called floating or submerged in 

 (3). Called submergents in (2).
