Der Einfluss von Aufnahmefehlern und Wachstumsvorgängen auf die Stammzahlverteilung in Buchennaturverjüngungen unter Altholzschirm: Vergleich eines naturnahen Buchenbestandes im Sihlwald, Schweiz, mit einem Bestand im Buchen-Urwald Uholka, Ukraine | The influence of survey errors and growth processes on stem distribution in young growth under old beech growth. Comparison of a close-to-nature beech stand in the Sihlwald, Switzerland and a virgin beech

Abstract

The young growth stem distributions in a 115 year old beech stand in the Sihlwald (Switzerland) and in a virgin beech stand in Uholka (Ukraine) show conspicuous sinks in the 130,0 to 169,9 cm tree height range. A model shows, that these sinks can be the result of height growth differences be tween trees in different height classes. Technical reasons of the surveys may accentuate the sinks. There may be more reasons which could play a role but these were not investigated.
