| Outline of Final Research Achievements |
This study aimed at analyzing stand development with the stand reconstruction technique that does not require accumulation of previous stand data. We managed to collect data on stand structure and stem samples from about 30 forest stands in Estonia, Finland, Siberia, Alaska, and NW Canada. Results suggested that there may be a pattern of stand development common to circumpolar boreal forests. The rapid cooling of the circumpolar region subsided in 1970's, which was followed by rapid warming thereafter. This rapid warming was associated with shifts in forest growth patterns from one growth curve to another. This discovery is being reported in an international scientific journal, Polar Science.
