Taiga
Boreal forest, Alaska, U.S., dominated by spruce trees (Picea).
The tree species that grows farthest north in the world is the Gmelin larch (Larix gmelinii), which has been found at a latitude of 72°40′ N on the Taymyr Peninsula in the central Arctic region of Russia.1
In North America, the northernmost trees are white spruce (Picea glauca), which grow along the Mackenzie River delta in Canada, near the shore of the Arctic Ocean. These species are part of the taiga, a biome characterized by its ability to survive in extreme northern environments with short growing seasons and long, cold winters.12
