Glaciation Soils and Stress Sensitivity of Spruce Trees in the Snowy Range

Hamann, Margo
Scientists have documented three major glaciations in the Snow Range Mountains and called these Pinedale, Bull Lake, and Pre Bull Run. All three have characteristic soil make up but support the same species of evergreens. It was predicted that the different soil make up from each site would determine how sensitive to stress the trees are. Using spruce from all three sites in a xylem conductivity experiment we found that there was a significant difference in stress tolerance between sites.
