We conducted to describe methods used to differentiate the zones of juvenile and mature wood in stems of coniferous species and to present the importance of good identification of the shares of both types of wood to ensure a rational use of the raw material and final quality of wood products. This study describes in more detail a novel method to separate the juvenile and mature wood tissue in stems of European larch using cluster analysis in the form of the k-means algorithm. Moreover, guidelines were also shortly described for forest management which could result in a reduction of the share of juvenile wood in stems of forest trees.

Keywords: differentiation methods; k-means algorithm; forest management
