The paper presents dynamics (in the period 1993-2004) of selected parts of upper mountain spruce stand of primeval character growing on the area of reserve Romanka in Beskid Żywiecki Mts. The changes of species composition, volume, DBH and height distribution, storey structure, the share of standing and laying dead trees and number of regeneration as well as the stand volume increment were determined on two sample plots. In the optimum stage (advanced ageing phase) stand volume increased from 465 m³/ha to 500 m³/ha, volume of dead standing trees decreased from 61 m³/ha to 51 m³/ha and volume of downed trees inceased from 49 m /ha to 58 m³/ha. In the desintegration stage stand volume decreased from 343 m³/ha to 258 m³/ha, volume of dead standing trees decreased from 83 m³/ha to 77 m³/ha and volume of downed trees increased from 83 m³/ha to 97 m³/ha.
