Objective(s): To determine soil organic carbon quantity and quality under open stands of Picea glauca and Picea mariana close to northern forest limits as opposed to open tundra and to enable predictions of forest propagation on soil carbon dynamics under extreme climate conditions.

Project Description: The objective of this study is to determine soil organic carbon quantity and quality under open stands of Picea glauca and Picea mariana close to northern forest limits as opposed to open tundra. To enable predictions of forest propagation on soil carbon dynamics under extreme climate conditions.

Taking samples from the soil and trees in the Richardson Mts., specifically at two points with the coordinates: 67°13'5.05"N 135°25'26.65"W and 67°13'37.41"N 135°27'58.15"W in the vicinity of the Midway Lake. The samples, 0.5 kg in weight each, would be taken along a line 1 mile long in each site, from soil pits 1 yard x 1yard x 0,8 yard. There would be maximum of 10 pits per site, which would be buried immediately. Stem cores would be drilled by hand from up to five trees per site (ca 2-3 mm in diameter), which would not harm the trees, since the void space will be filled with a special paste.

The study results will be communicated in the form of scientific papers and a plain-language report that would contain the summary of the findings and importance thereof.

The fieldwork for this study will be conducted from July 15, 2015 to July 25, 2015.
