Information on tree stem characteristics and dimensions is sparse, especially information that would enhance conservation and trade monitoring efforts for species where bark is harvested for medicinal use. Several tree stem characteristics were investigated during a study on the relationship between bark thickness and stem diameter, and this paper presents the mean height, branch-free bole length and wet and oven-dry bark thickness per stem diameter-class for six species. Additionally, prediction tables are constructed that allow bark thickness to be determined from diameter at breast height
