All forests have lots of trees, but there are different types of forests. They are often described as different biomes. One of the main differences is where they are located in relation to the equator and the poles. There are three main types of forest biomes: the rainforest, the temperate forest, and the Taiga. Rainforests are located in the tropics, near the equator. Taiga forests are located far north. Temperate rainforests are located in between.
