Taiga
Boreal forest, Alaska, U.S., dominated by spruce trees (Picea).
In North America, the northernmost white spruce trees grow along the Mackenzie River delta in Canada, near the shore of the Arctic Ocean.1
These trees mark the northern limit of tree growth, known as the tree line, where the taiga transitions into the tundra. While white spruce is the dominant species at the tree line in northwestern Canada and Alaska, the absolute northernmost trees in the world are actually Gmelin larch (Larix gmelinii), found on the Taymyr Peninsula in Russia.21
