The taiga is the world’s biggest biome.
It covers nearly one-fifth of the Earth’s land surface and stretches across northern Canada and northern Eurasia in an almost unbroken belt for 7,000 miles. The main features of the taiga are its evergreen forests of needle-leafed trees, including pine, spruce, hemlock, and fir. Although this biome is not as harsh as the tundra, all its plants and animals have evolved to survive the taiga’s long, snowy winters.
