We modelled Norway Spruce branchiness, in order to estimate wood quality of standing trees grown in monospecific even-aged stands from inventory data. We studied the whorl branches of the preformed growth unit. Their number, basal diameter and insertion angle were estimated. For delimiting crown base, we modelled heights to the first green branch, first green whorl and first dead branch. We started from a model previously established from young trees data representing the average fertility classes found in Vosges mountains. In this model, the averages of branch basal diameter and insertion ang... Mehr ...
