Alliances represent an aggregation of floristic associations and are characterized by one or a group of diagnostic species which, as a rule, occur in the dominant or uppermost stratum of the vegetation. The diagnostic species used to determine both the Alliance and Association are primarily the dominant species. When data indicate that additional diagnostic species (including differential, indicator, or character species) provide a better characterization of ecological patterns, they are used in addition to the dominant species to classify these floristic units.
