The paper presents an analysis of merchantable timber volume in three Scots pine stands aged 35, 50 and 88 years depending on Kraft's classes. It also shows the strength of the relationship between this volume and various measures of a tree's growth space (crown projection area, crown width, Seebach's growth space number, crown projection area ratio, space of a single tree and crown spread), crown characteristics (crown length and relative crown length), slenderness, breast height diameter and height as well as the biosocial position of a single tree. Volume of Scots pine merchantable timber trees was described using multiple regression equations.
