Above-ground dry matter production in three stands of Trembling Aspen

, : Above-ground dry matter production in three stands of Trembling Aspen. Canadian Journal of Forest Research 2(1): 27-33

Above-ground biomass, annual production and leaf area index (LAI) were estimated for several years in Populus tremuloides stands, 5, 15 and 52 years old in 1968, near Chalk River, Ontario. Based on regressions of dry weight on stem diameter, estimates of biomass (stems and branches) for 1968 were 21 500, 51 200 and 91 800 kg/ha respectively in the three stands. Net annual above-ground production in 1968 was 6900, 7000 and 1340 kg/ha respectively.
