Map of Tundra
                The Arctic Tundra is located in the
                  northern hemisphere encircling
                  the north pole.




                       This is were
                       the Arctic
                       Tundra is
                       located.
The Physical Conditions of
Tundra
                • Extreme cold climate
                • Little life
                • Simple vegetation
                    structure
                •   Limitation of damage
                •   Short season of growth
                    and reproduction
                •   Energy and nutrients in
                    the form of dead
                    materials
                •   Large population
                    oscillations
   Physical Conditions-Summer

• High temp: 54 F (-28 C)
• Cold temp: 37 F ( -70 C)
• Sun shines almost 24 hrs a day
• Warm
• Land known as the land of the Midnight
 Sun
   Physical Conditions-Winter

• High temp: -18 F (-28 C)
• Low temp: -94 F ( -70 C)
    Physical Conditions of the Arctic
•   Extreme cold climate
•   Little life
•   Short season of growth and reproduction
•   Simple vegetation
•   Harsh winters
•   Low average temperatures
•   Little snow or rainfall
•   Short summer season
•   Harsh winters
•   Extremely short growing seasons (6 to 10 weeks)
•   Long, cold dark winters (6 to 10 months) with monthly temps below
Plants and Vegetation
• Low scrubs, reindeer mosses, liverwursts, and
    grasses
•   400 varieties of flowers
•   Crustose and Foliosen lichen
•   The plants in the Arctic Tundra all adapted to
    their cold climates.
•   Arctic Tundra’s plants are short and grow
    together, to help resist the cold, and are
    protected by snow in the winter.
•   Growing seasons are short in the Arctic Tundra.
                      Arctic Willow
•   common name-Rock Willow or Arctic Willow
•   Scientific name-Salix
•   Species-artic
•   Found in North America tundra
•   Likes cold climates, tundra=perfect place
•   Salix artic=15-20 cm tall
•   Many shapes
•   Long branches that root when touches surface
•   Arctic Willow grow prostrate, shrub and carpet
•   Leaves are oval with pointy tips
•   Net like vines and long hairs that cover the leaves
•   Flowers of Salix=upright scaly spikes
•   Blooms in spring
                  Arctic Willow
• No fruit on it, only seeds
• Lateral roots are shallow because of frozen ground
    underneath the permafrost
•   Strongest growth season=forms a pesticide to keep bugs
    away
•   Adapted to permafrost by forming a shallow root system
•   Leaves of Salix adapted to the cold by forming hairs
•   A lot in the wild, but vulnerable
•   Helps vegetation system, and helps many mammals
           Purple Saxifrage
•   Grows on very rocky grounds
•   Earliest plants to bloom
•   Tiny leaves cover the plant’s short stems

    capture heat
•   May be found in southern Alaska, Central
    Washington Cascades, Wallowa Mts. Of
    northeastern Oregon, and many more
    places.
Arctic Poppy
• Grows in many places
• The flowers are made up of four petals
    formed into a cup-shape
•   Stems are hairy and 10 to 15 cm high with a
    single flower on each stem

    up the heat of the sun
•   Arctic poppies-yellow and white
       Where Artic Poppies like to
              hang out
• Likes to hang out in the Arctic meadow
• It likes to grow in the mountains, in the gravel beds
    and on rocky high plains
•   Likes to grow among the rocks because stones
    absorb heat from the sun and provide moist shelter
    for the roots.
•   Parts of the plants are poisonous is indigested
•   It is toxic to some mammals
•   Toxic level is very low

•   Tail called sweep, keeps fox warm
•   Arctic Fox-sharp teeth, sharp claws & thick fur
•   Small ears minimizes heat lose
•   Eats small mammals, insects & fish
•   Fallows polar bears for its left over kills
Environmental Issues
What’s predicted for the future?
•   No more Tundra
•   It will all melt away
•   Plants and animals will die
•   Blame global warming for the melting of tundra ice
•   Humans are contributing to global warming
•   Polar bear extinction
•   No more sea ice
•   All animals die out-living on or in the Arctic
•   No more Arctic
•   Ice will disappear-Arctic will disappear
•   If global warming doesn't stop
Environmental Issues
Changes good or bad?
•   Ice is melting fast, so the polar bears will become extinct-bad
•   Barely anymore food because polar bears use the water to catch their food-fish-bad
•   Bad-polar bears in danger
•   Arctic heats up
•   Arctic ice melting faster
•   Less sea ice for polar bears
•   Polar bears-have trouble surviving and finding food
•   If ice disappears-polar bear extinction
•   Polar bears-travel to hunt seals
•   Humans driving cars
•   Humans using electricity
•   Humans burn fossil fuels
• Burning coal, oil, and natural gas
Environmental Issues
How has man changed area now?
•   Polar bears in danger as artic heats up
•   Animals not used to warm temps and becoming sick and even dying
•   217 cubic kilo. (52 cubic miles) of ice sheet now melting every year
•   Ice sheets melting fast
•   Sea is melting also, just as fast
•   Driving cars
•   Humans contribute-global warming
•   Use electricity
•   Burn fossil fuels
•   Burning coal, oil& natural gas
•   Burning fossil fuels-passes gasses-trap heat from sun
•   This causes rise in temp
Environmental Issues
How has man changed in past?
• Ice covering almost all mainland
More info on the Arctic Tundra

• Windy place- 30 to 60 mph
• Like a desert-precipitation
• Precipitation- 6 to 10 inches/mostly snow
  falls each year
• Below soil-tundra’s permafrost
