The paper analyzes homogeneity of fir (Abies alba) and spruce (Picea abies) forest stands in the MU “Igman” using the homogeneity index (H-index) and Lorenz curve. According to established forms of Lorenz curves homogeneity level of stands deviates significantly from the homogeneous stands. The homogeneity level by values of the homogeneity index for poorer site capability corresponds with the even aged stands thinned by high thinning, but for stands of better site capability corresponds with selection stands. It was concluded that due to the “surplus” of trees in the higher and “shortage” in the lower diameter classes homogeneity level is greater in comparison to selection stands, while in cases where homogeneity level corresponds with homogeneity of selection stands that is consequence of the effects of better site capability.
