Biome Map- Tundra

The area that is considered a tundra is the North edge of the world.

Biome Description Tundra has low

temperatures, short growing and reproductive seasons, and it is also one of the coldest biomes.

PrecipitationArtic Tundra: yearly rain and snow is 15-25 cm.In tundra's closer to a body of water, it can measure up to 20 inches per year.The most precipitation is between February and March.

Latitude and Altitude55 degrees to 70 degrees North.Alpine Tundra- 10,000 to 15,000 feet.Arctic Tundra- ranges from 300 to 11,000 feet.

Plants and Adaptations 1. Bearberry- grows in dry,

non- nutrient soils.2. Diamond- leaf Willow-

grows only a few inches tall and grows a thick carpet.

3. Caribou Moss- can grow on the ground or on rocks.

4. Pasque Flower- grows low to the ground to keep out of the cold climate.

5. Labrador Tea- in the cold it forms a carpet on the ground.

Herbivores and Adaptations1. Musk Ox- outer and inner

wool coat keeps it warmer.2. Caribous- large,

spreading hooves support them in snow and marshy tundra in the summer

3. Arctic Hare- forage shelters in the snow to survive

4. Tundra Bumble bee- coat keeps it from losing heat

5. Arctic Spring tail- dehydrate in a small husk

Carnivores and Adaptations1. Ermine- they make their

dens in the crevices of rocks instead of trees.

2. Wolverines- can attack prey larger than itself.

3. Polar Bear- live on the northern edge to find food in the Arctic Ocean.

4. Wolves- change to a bright white color in the winter.

5. Arctic Fox- thick, fuzzy fur and body fat help them survive.

are the same)

sugar for the lichen while the lichen provides a solid substrate for the algae)

Benefits of the TundraOne benefit of the Tundra biome is the fact that is keeps in must of the carbon from decomposed plants due to them freezing before they decompose. Another benefit of this biome is the Tundra keeps the sea levels relatively low, if the tundra were to melt then the sea levels would go up and it would have a great effect on people living near the coasts. One of the reasons we should preserve the Tundra is so we can save the coasts and we can also save our atmosphere.

Biggest ThreatClimate Change- Global Warming, As the earth warms, the frozen area of the tundra will melt, completely changing the environment.

Wetlands There are rivers, lakes and shallow bays in the tundra biome that cover nearly 60% of the surface area.
