dc.description.abstractThis study develops a sound quantitative method for the assessment of the structure, location, and composition of transition zones adjacent to wetland communities in the Altamaha River Basin of Georgia. The resulting methods will be incorporated into a U.S. Army Corps of Engineers methodology for delineating wetlands. Six sampling methods, three similarity indices, and four analytical strategies were investigated. Phase I of the study consisted of evaluation of sampling and analytical methods and selection of the best method. The best method proved to be the use of (A.) 1- x 4-m contiguous quadrats for sampling along transects parallel to the moisture gradient and (B.) Jaccard's community coefficients for data analysis. Phase II of the study consisted of further evaluation of the best method. This method was found to be advantageous because: (1.) It does not rely on the use of indicator species; plant associations are used instead. (2.) It is uncomplicated, technically reproducible, and therefore amenable to the legal interpretation in defining wetland boundaries. (3.) The procedures are well documented in the literature. (4.) It is applicable to a variety of physiognomic types. (5.) Minimal training is required for proper application of the method by field personnel.en_US
