The amount of rainfall varies from 6 to 10 inches of rain a year. Summer lasts for 6 to 10 weeks, but the average temperature during warm months is less than 50 F.

Ecological Concerns

Although the Tundra biome doesn't seem that important, it is, especially considering it covers most the earth. It provides us with different animals and plants that help each other thrive. Also, the permafrost in Tundra can show change in climate and help show global warming. Speaking of global warming it is a major threat to Tundra, because it's melting the ice. Another threat is the oil spills that are hurting the animals. We need to help protect the Tundra and it's endangered species like polar bears and the arctic foxes.

Plant Life

The plants in Tundra have shallow roots to help grow in permafrost. They also have littler hairs/fuzz on their leaves to help stop strong winds and to prevent cold weather. Another thing they all have is that they grow low to the ground to stay sturdy during strong winds. Some plants have darker colors so they can easier absorb the small amount of sunlight. Lastly, a lot of plants are built to grow on bare rock so they don't need to worry about freezing soil.


Animals in tundra develop in order to survive in the cold weather in the Tundra. For example, some animals have thick fur to keep them warm. Others, will have a greater amount of fat to keep them warm. They also have small ears to minimize heat loss. Another adaption is small bodies that help prevent over exposure to the cold air. Lastly, they will have broad feet to make it easier to walk on rigid grounds. Other animals will hibernate during the cold seasons.

During the year animals have to work with or against each other to survive. A good example of cooperation between animals is when the caribou dig up bugs for the arctic fox to feed on, but there is also competition. For example, the musk ox and caribou feed on the same food and so therefore sometimes fight over their resources. There are predators to worry about. Some predator/prey relationships are wolves and caribou, polar bears and arctic foxes, herbivores and plants, and brown bear and arctic hares.
