"The process begins with regionalization of the landscape into units, each of which is relatively homogenous within and contrasts in one or more [?] features with surrounding areas. Next, the units are analyzed in a heuristic classification, ordered in general by [?] and soil wettness.
-inclusions
-3n:1 is SPD to PD
-We suspect that a more detailed typology of the ecosystems of oak [?]lands would have been po9ssibole but for the obliteration/disturbance of the ground layer -- robbing us of reliable biotic indicators of system [?].
-May [?] notice that ecosystems usually lump several soil drainage classes together, in fact to differentiate north and south slopes consistently. The current classification is a reliable typology of extant variation and that which may be inferred from historical records."
