Dwarf birch growth change - Torngat Mountains

The Torngat National Park monitors the growth and extent of dwarf birch along elevational transects at 5 locations to understand how shrubs are changing the tundra vegetation in the park and sub-arctic regions. Each transect contains 3 or 4 plots, at lower slope, mid slope, and upper slope. Cover, height, growth increment and browsing of Dwarf Birch, and also soil temperature, are recorded at each plot.
