| Methods: | Sampling Description: Duplicate 10cm x 10cm sampling quadrats are permanently installed at triplicate plots on the marsh platform in North Inlet, SC. Plants within each quadrat are tagged, and plant heights are measured monthly. Numerical Processing: Plant measurements are entered into an ACCESS database, then transformed to biomass using allometric equations (Morris and Haskin, 1990. Ecology 71(6):2209-2217). Data are reported as the mean biomass and standard error of the 3 plots (n=6). |
