2 Under the snow pack  The snow creates an insulating blanket which keep heat from the earth in.  By having this blanket of snow animals and plants can live in the snow.

3 Animals under the snow?  The most noticeable animals that live under the snow pack are voles, mice, squirrels, and grouse.  They use the snow as shelter from the cold as well as shelter from predators.  Voles and mice dig vents for air in the snowpack. It is dark in the tunnels but just enough light goes threw to make it comfortable to live.

4 Subnivean environment  Small mammals living under the snowpack are still in danger.  Shrews and ermine take advantage of there size and pursue voles into the snowpack.

5 Subnivean Part 2  Red Squirrels hide some of there food in the snow.  Red squirrels go under the snow pack to escape the cold temperatures.  The grouse dig a hole and stay in it only coming out to eat tree buds

6 Subnivean water animals  Fish have the roughest time surviving. Many fish die due to lost of oxygen.  Fish have to completely change there way of living because of the low oxygen and low amount of food.

7 Subnivean plants  Some plants tend to grow and flourish under the snowpacks.  The plants have an excellent source of water and enough photosynthesis to live. Making them ideal food for small mammals traveling threw the snow packs.
