Abstract
SUMMARY The present study was carried out in a group of compartments, covering 520 hectare, in the State Forest Reserve “Bloukrans”. The sample consisted of 650, 0,04 hectare circular plots. The analysis revealed some significant correlations between site factors (aspect and slope) and stand characteristics, correlations between density of regeneration and stand characteristics and intercorrelations amongst the latter group of variables. The beta-function was fitted to the observed diameter- and basal area distribution. The normal distribution however expressed the basal area distribution of all species combined more satisfactorily. A sampling intensity of 0,88% is required to bring the maximum error, with a confidence coefficient of 0,95, within 5%. The sampling study was combined with a pilot study of the efficiency of distance methods. Distance to the nearest tree produced a negative bias, but to the second- third- and fourth-nearest trees gave satisfactory results. In comparison with the standard meth...
