A principal-component ordination technique was applied to Domin-based data from the Cape Henrietta Maria raised-beach systems. Eight of the 11 associations originally extracted by Braun–Blanquet methods were retained while the remaining three showed good reason to be grouped into one. Multiple regression trend surface analysis was applied to selected dependent variables mapped onto the ordination, and showed significant large-scale variations in the distribution of these points that were related to ecological factors.
