Die Unterschiede im Durchforstungsvolumen von Buchenbeständen in Abhängigkeit von der Höhenkurve des Gesamt- und des ausscheidenden Bestandes

Summary

For two long-termed thinning trials in 36 to 48 year old beech stands in Slovakia the crrors of thinning volume calculation are investigated for six types of stand height curves (h=f [d]).

The least errors were calculated on the basis of theKorsun type height curve, followed by theProdan and parabola height curve types. In crown thinnings the height curves of the thinned stands, in most cases, lay above those of the remaining stands. In the low thinned plots the height curves of the thinnings, in general, had a lower level than those of the residual stands.
