A total of 58 trees was sampled from eight stands across a large area of interior Alaska. Regression equations were developed to estimate standing aboveground biomass for 22 white spruce (Picea glauca (Moench) Voss) stands. Aboveground standing biomass of white spruce in mature stands ranged from 0.92 to 23.28 kg/m super(2) and current annual production ranged from 89 to 2853 g multiplied by m^-2 multiplied by year^-1.
