Tundra Biome

By: Emily, Kyle, Trey, & Jax

Location and precipitation

-Distribution: The tundra biome is restricted to the high latitudes of the northern hemisphere in a belt around the Arctic Ocean. Many of its species, both plant and animal, have circumpolar distribution areas
-The tundra is an unusually cold and dry climate. Precipitation totals 6-10 inches of rain a year, which includes melted snow. The tundra seems like a wet and soggy place because the precipitation that falls evaporates slowly, and because of the poor drainage caused by the permafrost.
-low precipitation (less than five inches/year) coupled with strong, drying winds. Snowfall is actually advantageous to plant and animal life as it provides an insulating layer on the ground surface.




Animals and facts

Animals -Polar bear, arctic hare, arctic fox, caribou, snowy owl.
Facts -Extremely cold climate, low biotic diversity, simple vegetation structure, limitation of drainage, short season of growth and reproduction.

Temperature and Plants

-Temperature- The short summer lasts only 6 to 10 weeks. It never gets any warmer than 45 or 50° F. The warmer weather causes a layer of permafrost, ice that never goes away in the ground, to melt, creating bogs and shallow lakes that don't drain.
