Methods:Five transects were laid out in along Greenwood Creek . These varied in length from 25 through 50 m. Two transects along Clubhead Creek were the same ones used as reference for the haying study. These are about 150 m long. Line intercept method as described in Brower, J., J. Zar, and C. von Ende (1990) Field and Laboratory for General Ecology. Wm. C. Brown was used to derive percent frequencies of different plant species. Transects typically start at edge of marsh creek and run perpendicular to upland. Lengths of individual transects vary from 35-150 m depending on the shape of the marsh sites and the number of transect line differed for the four sites. The presence of species within each one meter interval along the transect line was recorded. Absolute and % frequencies can then be calculated.
