In summary, these include, but are not limited to, the following: 1. Biotic communities recognize faunal as well as floral distributions, thereby allowing inferences to be made as to the occurrence and relative abundance of specific plants and animals Page 13 within a given formation-type. The biotic-community designation thus facilitates the meaningful inventory of common species as well as rare and endangered ones. For example, most populations of the eastern fox squirrel (Sciurus niger),as well as the rare and endangered red-cockaded woodpecker (Dendrocopos borealis)are contained within the Southeastern Deciduous and Evergreen Forest biotic community.

This same area could also be Intermountain Grassland if one were sampling an association to be mapped at a scale of 1:15,625. Our purpose in presenting this classification system is neither to promote a new concept nor to replace existing classifications. Instead, we are attempting to present a hierarchical synthesis of the existing works on North American biogeography to aid in the development of a universal classification system for the world's natural environments. We recognize that portions of the classification system are dated or incomplete and require additional work.
