Abstract

The morphological characteristics of a young yellow birch stand (Betula alleghaniensis Britton) were studied according to class height and class development, according to the classification criteria set by IUFRO. The results show that the crown projection ratio, b/dhp, and the ratio h/dhp are strongly correlated to the social position and the vitality of the trees. During clearing, these two morphological ratios should be considered in distinguishing among primary, unseful accessory, and harmful accessory trees. The differentiation of trees in social classes is emphasized by competition for growing space and will result in the modification of the dynamics of tree morphology and stem growth volume.
