Zusammenfassung der Vegetationshöhenstufen in 3 Klassen. Die Definition der Vegetationshöhenstufen im LFI (Brändli und Keller 1985) basiert im wesentlichen auf den Arbeiten von Ellenberg und Klötzli (1972) sowie von Kuoch und Amiet (1954, 1970). Berücksichtigt wurden auch die Arbeiten von Landolt (1983) sowie von Hess, Landolt und Hirzel (1967). Die Vegetationshöhenstufen werden über die Verbreitung der natürlichen Waldgesellschaften nach Wuchsregionen definiert. Da im LFI die Waldgesellschaften nur auf einem Unternetz im Waldareal erhoben wurden, diente der Bonitätsschlüssel von Keller (1978, 1979) als "Brücke". Eingangsgrössen für das LFI-Modell der Vegetationshöhenstufen sind die Höhenlage, die Exposition, die Azidität des Muttergesteins und die Wuchsregion. Die Abgrenzung des Waldareals nach oben (natürliche Waldgrenze) erfolgte aufgrund der Arbeit von Brockmann-Jerosch (1919). Die Vegetationshöhenstufen werden in Abhängigkeit von Keller-Region, Acidität des Muttergesteins, Exposition und Höhenlage hergeleitet.
