The taiga biome is sometimes called a coniferous forest. This is because it is home to many coniferous trees such as pine, spruce, fir, and hemlock.

Taiga biomes are found between 50 and 60 degrees north latitudes. The taiga is the largest land biome on Earth, covering over 15 percent of the Earth's land. A large area of taiga is located in the northernmost forests across Europe, Asia, and North America. The taiga generally has two seasons. The summers are short, moist, and warm. The winters are long, cold, and dry. Most precipitation is in the form of snow, though rain does occur during the summer. Most animals in the tundra hibernate or migrate during the winter. Hawks, bears, foxes, wolves, deer, bats, and chipmunks can be found in the taiga.
