Objective(s): Our research is concerned with the growth and reproduction of the small spruce trees found north of the treeline in the Tuktoyaktuk region. These white spruce clones are the furthest north spruce trees in North America, and are typically found in small clusters or "tree islands." The objectives of our research is to determine the age, growth rates and reproductive rates of the tree islands in the region, and to relate these to past changes in climate

Project Description: The researchers will measure various parts of the trees and take seed samples found on tree islands. They will take small cores from the base of the largest stems to determine age and growth rates. The tree rings can show how well the tress were growing in the past, and this can be related to changes in the climate.
