Chapter 3. The Plant Community<br />
The two most fundamental aspects <strong>of</strong> <strong>the</strong> plarlt<br />
C~xnnlurrity <strong>in</strong> red maple swamps are community<br />
~LrucLure md floristic composition. Community<br />
sk;ructurc refers (x, <strong>the</strong> composition <strong>of</strong> <strong>the</strong><br />
plant cornnxunity <strong>in</strong> terms <strong>of</strong> vegetation height,<br />
density, percent cover, and similar characteristics,<br />
and *,he relative development <strong>of</strong> various life-form<br />
layers. Structure is <strong>of</strong> special importance beeatme<br />
<strong>of</strong> lts relation to certa<strong>in</strong> wetland functions<br />
and valaxea, such as wildlife habitat, flood flow<br />
ralteratioxr, and forcst biomass production. The<br />
floristic corrxposition <strong>of</strong> a swamp, like its structure,<br />

Kershner 1977; Greller 1977; Messier 1980;Huenneke<br />
1982). The majority <strong>of</strong> <strong>the</strong>se surveys were<br />
carried out <strong>in</strong> Connecticut or on Long Island, New<br />
York. Only a few studies (Ca<strong>in</strong> and Penfound 1938;<br />
Vosburgh 1979; Laundre 1980; Braiewa 1983;<br />
Lowry 1984; Swift et al. 1984) have been designed<br />
specifically to exam<strong>in</strong>e some aspect <strong>of</strong> red maple<br />
swamp ecology Quantitative studies have been<br />
limited primarily to sou<strong>the</strong>rn New England (Anderson<br />
et al. 1980; Messier 1980; Braiewa 1983;<br />
Lowry 1984) and New York (Stewart and Merrell<br />
1937; Goodw<strong>in</strong> 1942; Huenneke 1982; Malecki<br />
