Abstract: Equations and tables are presented for estimating above-ground tree component dry weights for fully stocked aspen (Populus tremuloides Michx.) stands up to 40 years old growing on different sites in the mixedwood forests of Alberta and Saskatchewan. The dis tribution of biomass components in relation to stand age was analyzed, which indicated that with increasing age the proportion of leaves declines while the proportion of stem wood increases. Optimum rotation lengths were calculated based on culmination of bio mass mean annual increment (MAl). Opti mum rotation was around 30 years for all conditions, but the estimated maximum total above-ground biomass MAl ranged from 4.8 t· ha-1 on better sites (site index 24 m at 50 years) to 2.2 t· ha-1 on poorer sites (site index 16 m).
