 Tundra  Cold frosted area  Layers of ice are formed on top of the soil

 Ranges from 36°F to 54°F in the summer  Average of 30°F in the winter

Because there are only a little precipitation the snow and wind is an important factor in the reserve.  Yearly precipitation is 15-25cm  The snow makes shelter for the animals

Not sociable Fight each other Live in wet tundra areas Browse at night Hide in thickets at daytime Each year a female produce 4-8 babies Hunt day and night Live in open tundra meadows and fields Feed on rodents

Depend on their sense of smell Dig a lot around their den Hunted by humans

Biotic (larger land animals) Travel in herds Migrate between summer and winter ranges Roam their territory In winter they semi hibernate Low metabolism rate

Agile and surefooted like goats Horns are to defend and ward off predators They wade into water to escape predators Tufts sharpen their hearing Thick fur allows it to hunt silently in the snow Snowy regions Do not hibernate They can travel to 30km in search of food

 Oil drilling can effect the plants and animals  It can also effect the natural beauty of the Arctic National Wildlife Reserve  It can destroy the natural habitat for the animal To Solve the Problem: Human should stop oil drilling
