In last decades, intensive research of the forest trees biomass increment changes has realized in the context of the presumed global change because forest stands have shown crucial share on the carbon storage in the global scale. Relationships between tree dendrometric parameters and forest tree biomass using allometric equations or expansion factors are still solved insufficiently. Changes of the structure of the adult highland spruce stand at the study site of Rájec (the Drahanská vrchovina Highland) in 2009 - 2012 and allometric equations and expansion factors determined for an aboveground biomass of the studied stand (and its single fractions) are described in the present study. Belowground biomass of the studied stand was estimated using known allometric relationship. Diameter at the tree breast height was suitable parameter for the estimation of the stem biomass volume (with and without bark) and it was the suitable input parameter for most allometric equations for the estimation of the aboveground biomass or its single fractions. Significance of tree competition to estimate tree biomass was established. Thus, using competition parameters in allometric equations is appropriate in some cases. There was calculated expansion factor for the aboveground biomass 1,30 and for the belowground biomass 1,18 in the studied adult spruce stand.
