The Associations of the Marsh Habitats 



In the low ground back of the fringing dune and south of Beach 

 are two small bodies of water known as the Dead River and the Lit- 

 tle Dead River. The former expands in width as it nears Lake 

 Michigan and becomes what is know as Dead Lake. The small 

 drainage area commanded by these rivers is very level, and conse- 

 quently there is very little flow of water. For the greater part of 

 the year the outlets into Lake Michigan are closed by a ridge of sand. 

 The surplus water, at these times, is partly evaporated away, partly 

 sinks through the sand to the lake-level, and is partly taken up by 

 the plants which grow along the shores. In general physical charac- 



*The asterisk denotes that the species spreads in from surrounding areas by- 

 vegetative growth.
