Characteristics ClimateThe tundra is very cold and receives less than 10 inches of precipitation a year, mostly in the form of snow. It has temperatures averaging below -35 degrees Celsius. The short summer last only 6-10 weeks. Despite the cold climate 1700 different kind of plants grow in the tundra. The only difference between the arctic and alpine is that the soil in the alpine tundra is well drained.

• Animals in the tundra biome all have special adaptation skills to adapt to the cold climate. There is low biodiversity in the tundra so if one species population changes it will affect others.

Wildlife

Some tundra animals include: Polar bear Caribou Arctic fox Killer whale Reindeer Moose Sea lion Bald eagle

• The tundra contains over 1700 different kinds of plants. These plants are useful resources for the animals and even humans.
