GRowth variability in Arctic Forests: slam or jam to resilient bioeconomy

Arctic forests are under strong influence from ongoing changes in global climate system. Tree-ring analysis provide an excellent tool for investigating the growth variability of trees and revealing the varying climatic factors that have impacted the growth variations through time. Tree growth data representing Arctic forests is analysed for annual-to-decadal growth variability to gain insights to improve our information-based understanding of this climate-dependent resource for bioeconomy. These growth trends are also placed into a longer-term context using the archived tree-ring chronologies from the same region. In the GRAF project, the NFI-based [National Forest Inventory] growth estimations will be tested for the hypothesis that these trends are related to ongoing changes in high-latitude climate and analysed for spatial details and temporally characterise the trends.
