Adopted modelling approach is explicitly empirical
and management-oriented: the purpose was to predict
site index by quite easily measured factors rather than
relying on intensive, process-oriented techniques.
However, the developed model proves to be suf®-
ciently sound, both from ecobiological and statistical
points of view. It may be used to effectively augment
the practical knowledge of ®eld forest staff, at least
with reference to the study area.
