AlpineFeature
Location All over….Mountain BiomeCan be in middle of desert
Temperature ColdColderer as you go up the mountain
Rainfall Average/ 30cm
Plants/Adaptation Cold shallow soil, Conifers mosses and lichens
Animals/Adaptations
Cold Rocky terrain, Fur and hooves, Mountain goat
Other names Mountain, Alpine Tundra
Special Features Can be in the middle of the desert and still get snow. The bottom of the mountain is warm and colder as you go up. Biome changes as you go up the mountain.

Boreal• Boreal Forest Biomes also known as TAIGA• far north mostly cold, • Canada and Alaska. • Coniferous Trees • Have needles• Do not shed leaves• Reproduce with cones. • Spruce and Pine Trees. • Animals Depend on trees for food and habitat. • mammals adapted to cold• carnivores such as wolves to eat large herbivores
such as elk

• Many carnivores such as wolves to eat large herbivores such as elk
• Mountains and Ice• Do not fall into major biomes. • Mountains have several mini-biomes. • The climate is different at the base of
moment than at top. • Different plants and animals live at
different parts of mountain. • Some parts of earth are covered in ice. • Arctic and Antarctica. • Animals such as penguins and seals.
