To derive the biomass from satellite measurement, it is inevitable to acquire in situ biomass by ground-based survey. We applied a way that is a combination of Bitterlich Angle Count Sampling method and Sampled-tree Measuring (BACS-STM) method as a quick method for biomass measrement. In July 2007, a forest survey was carried out in the south-north transect (about 300km) along the Trans-Alaska Pipeline which profiles the ecotone from boreal forest to tundra in Alaska. Biomass at 29 forests in the transect were measured by the BACS-STM method. It was revealed that the forest biomass distribute from 5 to 100 ton/ha (dried matter).
