Tundra

Vast, treeless Arctic region in which the subsoil is frozen

Climate

The average winter temperature is -30 degrees F. The average summer temperature is 37 to 54 degrees F. The average rainfall yearly is 6-10 inches. The tundra has an extremely cold climate and a short season of growth and development. In the winter it is cold and dark. In the summer it is soggy because the layer of permafrost melts.

Vitals of Biome

The tundra is located between the 60 to 75 degree latitude lines. Some of the abiotic factors include little rainfall, strong winds, low temperatures, and poor soil.

Ecological Concerns

People who moved to the tundra to work in mines and oil rigs have disturbed animal life by building towns and roads. The feeding habits of the animals have been disrupted, and as a result many polar bears have starved to death. The Alaskan oil pipeline was built across caribou territory, and in some places the caribou are unable to pass over it. Pesticides have been used to control insects, so the birds who feed on those insects have been affected. Pollution from mining has polluted the air, rivers, and lakes. The tundra is a fragile environment, and it doesn't take much for it to be damaged. With that said, humans need to be careful so that they do not damage this biome.

Fun fact: The tundra is the world's youngest biome.
