Objective(s): To measure plant species composition and cover in mesic, upland sites within the subarctic forest, at the treeline and in the tundra in order to determine changes in the plant community structure through the treeline ecotone; to determine locations for permanent plots to monitor long-term changes in plant communities through the treeline; to begin research on the population ecology of isolated white spruce tree-islands beyond the treeline.

Project Description: This study continues from the research conducted in 1991 where we examined the plant community and assessed plant distribution as the subarctic forest changes to tundra. We are interested in how the smaller plant species are influenced by changes in the number of trees that are nearby as well as changes in climate. Permanent plots will be established in order to monitor any changes in the plant communities over a long time period.
