Abstract

The IUFRO classification criteria were applied to yellow birch stems in a lower pole stand located in the Saint-Zacharie experimental forest. Mensuration data were analyzed using the classification criteria. The results show that the stand in which yellow birch predominates has a relatively homogeneous diametrical and vertical structure. Social differentiation and some species hierarchy are evident even at this early stage. Mensuration data analyses reveal the discriminatory value of several IUFRO criteria (height class, development class, silvicultural class); other criteria (evolutive trend class, technological standard class) are more difficult to apply. The suggestion is made that two indices (ht/dbh ratio, crown clearance) would facilitate tree classification in young hardwood stands.
