The Tundra
Characteristics

Permafrost
Treeless
Light precipitation
Frigid temperatures
Two variations
Alpine Tundra
Arctic Tundra

Location
Arctic Tundra
Northern Alaska
Northern Canada
Northern Russia
Greenland
Alpine Tundra
World wide at high altitudes
Between 10,000 and 11,000 ft
6-10 inches a year including melting snow
Permafrost limits ground draining
Cold swamp for insects and plant growth
Precipitation
Climate
Similar between Arctic and Alpine
2 Seasons; Summer and Winter
High winds throughout the year

Global Impact
Threats - Drilling for oil in the ice damages the ecosystem as well as many people settling the land.
- Global warming is damaging the Permafrost which contains lots of Carbon Dioxide.

Resources -
- The arctic region of Russia has deposits of nickel, copper, coal, gold, uranium, tungsten, and diamonds.
- The North American Arctic yields uranium, copper, nickel, iron, natural gas, and oil.

Ecosystem - Very fragile despite the harsh conditions, any change in life has huge impacts on the food chain. It also has a slow natural recovery rate due to minimal growing seasons.
Temperate Deciduous Forest
Characteristics
- Four distinct seasons
- Mid-latitude areas
- Warm and cold air masses
- Generally 3 levels of vegetation
Location

- Temperate zone between tropical forests and coniferous forests.
- Most of Europe, eastern North America, Japan, and parts of Asia were covered
- Now most of the forests are gone but some places are protected.
- The Great Smoky Mountains in North America have been designated a world biosphere reserve.
Precipitation
Precipitation
- The 20 to 60 inches of precipitation is distributed evenly throughout the year except during the colder winters.
- There is an approximately 6 month growing season.
- The non-growing season is due to temperature-induced drought during the cold winters.

- There are 4 distinct seasons.
- Mild summers avg temps being about 70°F
- Winter avg temps being about 30°F
- Almost all of the world's deciduous forests are located by an ocean.

Plants
- Symbiotic relationship with fungus
- Shallow roots
- Mosses, lichens, low-to-the-ground shrubs, and sparse trees and few flowering plants.
Labrador Tea
Caribou moss
Arctic Willow
Arctic Tundra Moss
Animals
Strategies evolved to withstand the harsh conditions of the tundra can be divided among those species that are resident and those that are migratory.
Resident
Large, compact bodies
Hibernation
A thick insulating cover of feathers or fur
Plumage that turns white in winter, brown in summer
Ability to accumulate thick deposits of fat during the short growing season.
Smaller ears and short bodies to conserve body heat and reduce skin that is exposed to the cold.
Ribbon seal
Lemming
Arctic cookie star
Hoary Marmot
Ermine
Gyrfalcon
Rock Ptarmigan
Narwhal
Pika
Fungus
The experts say the Alaskan and Canadian tundra are the most infested areas.
