then fed in turn on southern bulrush, Olney'ts three-square, big 
cordgrass, and reed. 
At the beginning of the study the vegetation of the transect 
consisted of isolated patches of saltmeadow cordgrass, remnant stands 
of big cordgrass, ee and various annual plants. 
An early burn on the first portion of the transect prevented 
measurement of open space in 1954. 
Transect C was located north of Belle Isle in Vermilion Parish 
on property of the Louisiana Fur Corporation. It started on the 
north slope of Belle Isle ridge and extended 4,900 feet in an easterly 
direction, passing through the following zones of vegetation: 
1. Ridge vegetation of saltmeadow cordgrass, paspalum, and 
sedges, 900 feet. 
2. Alternating or mixed stands of reed and big cordgrass with 
saltmeadow cordgrass, 1,100 feet. | 
3. <A pure stand of reed with a ground cover of saltmeadow 
cordgrass, 600 feet. 
4, Saltmeadow cordgrass growing in an old marsh buggy trail 
through a stand of reed, 1,000 feet. 
5. A marsh grown to saltmeadow cordgrass with a little Olney's 
three-square, 1,300 feet. 
Transect C was situated adjacent to an area of large nutria 
populations; and, according to trappers, nutria were moving onto 
the transect area.
