Objective(s): To study population ecology of isolated white spruce clones beyond the present treeline; to determine how special plant communities on south-facing slopes change through treeline; and to determine the succession and regeneration patterns in burned sites of different ages in the forest-tundra.

Project Description: The researchers want to determine the age of the isolated "tree islands" and how they manage to grow so far from the treeline. Researchers look for old stems for carbon dating, and map the position of each stem. The age and growth rates of the trees are determined by counting and measuring tree-rings. This year plant communities found on south-facing slopes down the Anderson River will be studied. Rare, southern species of trees are present here.
