Why do so few trees grow in the tundra?

Although most biomes on Earth are covered in trees, the tundra is known for its lack of trees. The term tundra actually comes from the Finnish word tunturia, which means 'treeless plain.' The tundra has very few trees due to several factors. First, the short summer season results in a short growing season, which makes it difficult for trees to grow larger. The persistent and strong winds also make it difficult for large trees to survive due to damage caused by the wind. Additionally, the permafrost makes it difficult for roots to penetrate the soil and create a strong support base. The cold temperature of the permafrost also makes decomposition slower, which limits the amount of nutrients being cycled through the environment.

Although there are few trees in the tundra, there is a variety of smaller vegetation that grows in this environment. Plants that are commonly found in the tundra biome include dwarf shrubs, grasses, mosses and lichens.

Hope this helps ;)
