The location is towards the top of the world. It goes around the North Pole.

General Characteristics

Some general characteristics of the Tundra are extremely cold climate, low biotic diversity, simple vegetation structure, imitation of drainag, short season of growth and reproduction, energy and nutrients in the form of dead organic material

Weather, Climate and Tempature

It is cold through all months of the year. It never gets any warmer than 45 or 50° F. During winter the average tempature is -20° to -30°F. The tundra is an unusually cold and dry climate.


The precipitation is quite extreme, with only 6 to 10 inches of rain or snow per year, the tundra is as dry as the driest desert.


Animals that live in the tundra have specialized adaptations which allow them to survive in such extreme temperatures.

Here are some mamals that live in the tundra.

Arctic Fox

Killer Whale

Sea Lion

Ground Squirrel


Seal Beluga



Here are some birds that live in the Tundra.

Arctic Loon

Emperor Penguin,

Long Eared Owl

Rose Breasted Grosbeak

Bald Eagle


The tundra is not a plants best place to grow because perma frost (the permanently frozen soil) that is about a finger-length under the surface in the summer months prevents the plants' roots from growing as long as they need.

Catastrophic Events

The most severe threat is global warming. In 2007 the Anaktuvuk River fire burned 1,039 square kilometers of Alaskas Arctic Tundra, increasing by two-fold the area burned since 1950 across the entire Arctic tundra biome.

Human Impacts

Human impact on the tundra has generally not been a positive one. Because the tundra is such a delicate environment, even the slightest change in conditions can threaten the entire biome. Recent human activities have largely undermined the habitat of the indigenous wildlife through pollution and overdevelopment.
