Picea mariana
Much of the landscape, including the Athabasca Plain, is the boreal forest that covers so much of Canada at this latitude, consisting of black spruce ("Picea mariana"), jack pine ("Pinus banksiana"), quaking aspen ("Populus tremuloides"), white birch ("Betula papyrifera"), balsam poplars, white spruce ("Picea glauca"), and balsam fir ("Abies balsamea"). The dominant tree of the wetlands is black spruce, while the rocky outcrops are covered with lichens.
