The purpose of this study was to delineate communities cartographically within a 176 acre prairie in Trego County, Kansas. The communities were then characterized as to vegetational structure, underlying soils, and topographic position. An attempt was also made to discern causal factors influencing species distribution. Seven communities were recognized and mapped onto an aerial photograph. The communities identified were: Buchloe-Bouteloua, Buchloe-Bouteloua-Agropyron, Bouteloua, Bouteloua-Andropogon, Andropogon gerardi, Andropogon scoparius, and Kochia. The communities were found to be primarily the result of a moisture gradient established through the combined effects of topography and soils. Degrees of success varied for all species throughout the moisture gradient, thus, species with similar tolerance were aggregated into communities.
