ABSTRACT
Biomass of stands of common alder (Alnus glutinosa (L.) Gaertn.) in the Niepołomice Forest is 120.97 (t.ha-1) on the average. Almost 98% of this quantity is accumulated in the tree layer, while about 2% in the underbrush layer. Wood is the main part of biomass (about 80% on the average), especially wood of tree stems (69%). The percentage of the assimilative apparatus in biomass of stands is somewhat less than 2% (2.24 (t.ha-1)), but it makes over 35% of the annual production of dry matter amounting to 6.156 (t.ha-1) on the average.
Key words: common alder, stand, biomass, annual increment.
