Project Description: This license has been issued for the scientific research application #868. The objectives of this research are to determine what changes have occurred in spruce trees near the treeline in response to the warming climate of the Mackenzie Delta region over the past 20-50 years. The researchers will visit sites measured in the early 1990s and repeat the same measurements, which will allow them to see if there are more trees and if they have grown faster and produced more and better seeds. The measurements to be taken will include: tree heights and diameters; tree age – from cores removed from the tree using a tree corer; vegetation composition near the trees – assessment of species composition and abundance using standardized methods (including photographs of plots); seed collections will be made from white spruce trees (Picea glauca) at each site and the seeds will be tested for germination. This project is part of a larger project on treeline dynamics across Canada (PPS Arctic Canada), funded by the federal government's International Polar Year program. Results of the field season will be available on the PPS Arctic Canada web site. The researchers will also contribute to a plain language PPS Arctic poster which will be translated and sent to communities throughout the North. Copies of all publications from the research will be provided to the ARI library. This fieldwork will be conducted from September 5 to 9, 2008. The exact sites are not precisely located because they were originally visited in the early 1990s, however, they will be located close the following coordinates (taken in 1990): R1 (69o28'N 134o19'W), R2 (69o23'N 134o02'W), T1 (69o23'N 133o30'W), T2 (69o19'N 133o44'W), T3 (69o19'N 132o 49'W), T4 (69o28'N 132o 10'W), T5 (69o11'N 133o01'W), T6 (69o18'N 132o33'W), T11 (69o17'N 132o52'W), T12 (69o05'N 133o16'W), T7 (69o15'N 131o50'W), T8 (69o11'N 131o27'W), T9 (69o06'N 130o59'W), T10 (68o17'N 133o15'W).
