TUNDRA
Land of the midnight sun.
LOCATION
 Tundra is located near the north pole at the top of the earth.
 Covers 1/5th of the earth.
PRECIPITATION
 The climate in the tundra is similar to tropical deserts
 Tundras are dry places and get around 6-10 in. of rainfall annually
 Melting snow makes the ground soggy despite the dry nature of
the biome.
TEMPERATURE
 The summers are only around 6 weeks long and the temperature
often doesn’t reach above 50 degrees
 The winters are the longest season of the month and temperatures
are -20 degrees on average but can get as low as -40.
AMOUNT OF LIGHT
 Tundra is often called “Land of the midnight sun”
 In the winter (for as long as 2 months) the sun doesn’t reach above
the horizon whereas in the summer, the sun is out for 24 hours a day
 This is due to the geographic location of the tundra
AIR QUALITY/ SALINITY
 Salinity in the tundra is VERY LOW
 The pollution added to the air in the tundra recently has caused the
infections of lichens, a vital food to many organisms living in the
tundra
NUTRIENT LEVEL
 Low nutrient levels for the tundra
 This is because the moisture and low temperatures are hard to
decompose
 The soil is very weak as well
 Any nutrients aren’t in forms needed for consummation from
producers and class one heterotrophs etc.

MAN’S INFLUENCE
(CAUSE AND EFFECT)
•The melting of the permafrost as a result of global warming
could radically change the landscape and what species are able
to live there.
•Ozone depletion at the North and South Poles means stronger
ultraviolet rays that will harm the tundra.
•Air pollution can cause smog clouds that contaminate lichen, a
significant food source for many animals.
•Exploration of oil, gas, and minerals and construction of
pipelines and roads can cause physical disturbances and habitat
fragmentation.
•Oil spills can kill wildlife and significantly damage tundra
ecosystems.
•Buildings and roads put heat and pressure on the permafrost,
causing it to melt.
•Invasive species push aside native vegetation and reduce
diversity of plant cover.
