Critical environmental factors in the freshwater marsh 

 include depth of water, salinity, rate of siltation, turbidity of 

 the water and competition for light and space. 



Bog. 



Bog communities are divided into two different phases, 

 s phagnum b ogs and ced ar swamp s. All bogs nave several features 

 in common. They generally develop in areas where drainage is 

 restricted, all have a surface layer of cushion-like vegetation, 

 and all have an accumulation of peat. The decidedly acid condition 

 of bogs limits the species which can persist here. 



Sphagnum bogs are more typical of the mountain region and 

 the far north, however, particularly in the northern section of the 

 Atlantic Coastal Plain, they occur scattered across the landscape. 

 Very few sphagnum bogs have persisted in the Chesapeake Bay region. 

 The vegetation is generally low to the ground with the exception of 

 some scattered shrubs and trees. Two mosses Sphagnum and Hypnium 

 dominate the bog by creating a covering over the entire surface. 

 Other species scattered through the bog include buckbean Menyanthes 

 trifoliata . cotton grass Eriophorum spp. , numerous sedges Carex 

 spp . , cranberry Vaccinium macrocarpon , sweet gale Myrica gale, bog
