It is suggested that communities of cultivated forests can be incorporated into the system of “natural” wood communities either as facies, variants or subassociations, if they differ below the association level; if they differ on the association level, a new association is suggested, with the prefix “culti-” before the planted dominant tree species. Most of our planted forest communities differ on the level of association or less; the communities ofRobinia are the exception. The authors agree withJurko (1963) in classifying them as individual associations, alliances, order and class.
