DESCRIPTION: The importance of Boreal and Arctic landscapes is recognized by the scientific community as an important area of research. The overarching theory to be tested in this proposal is that the current controls over vegetation growth are not operating as they have been in the past. The investigators have at hand a detailed network of ground measurements of tree-ring data collected across a range of Boreal and Arctic forests and shrublands sites in Alaska and adjacent Canada. This data will be compared with satellite based remote sensing proxies of vegetation productivity. The work is by and large an analysis and comparison of two independent methods for assessing vegetation growth variability in Arctic ecosystems.
