Critical environmental factors include amount of salinity, 

 frequency of inundation, and depth of water. 



Freshwater Marsh 



As with the salt marsh community, the freshwater community 

 is divided into two phases, the coastal freshwater marsh phase and 

 the inland freshwater marsh phase. The primary source of water for 

 these marshes is precipitation and runoff via rivers and streams and 

 thus a totally different type of community develops. 



The coastal freshwater marsh phase occurs along rivers and 

 streams where there is little or no tidal action as well as in 

 interdunal areas. The water is fresh or slightly brackish and 

 ranges in depth from ground level to several feet. A great diversity 

 of plants is distributed in these marshes in response to variation 

 in depth of water and salinity. 



In areas where water is usually fresh, plants such as 

 cattail Typha spp . , wildrice Zizania aquatica , sawgrass Cladium spp . 

 pickerelweed Pontederia cordata , and waterlily Nymphaea odorata 

 may form extensive stands. In the more brackish areas, species 

 characteristic of the more saline environments occur including tall 

 cordgrass Spartina cynosuroides and Olney's threesquare Scirpus 

 olneyi . Other typical species of the coastal freshwater marsh are 

 smartweeds Polygonum spp . , spikerushes Eleocharis spp . , sedges
