Research Abstract

Stem samples and data were collected from 28 forest stands during the study period in Canada, Alaska, Estonia, etc., and were analyzed. There was a rapid and widespread warming in the Arctic region during 1930s and 40s. Biomass accumulation in forests was shown for the first time to have declined substantially during this period. Analyses of the relationship between climate factors and forest growth still remains to be conducted, and we continue to work on this task to reach the original objective of this project
