The Taiga Biome
  • Also known as a coniferous forest or boreal
  • Largest terrestrial biome
  • A subarctic, evergreen coniferous forest of
    northern Eurasia located just south of the tundra
    and dominated by firs and spruces.
  • Location Northern portions of North America,
    Europe, Asia, extending southward at high

  • The taiga climate is cold arctic air. Cold winds
    bring in cold air from the Arctic Circle.
  • Because of earth's tilt, the taiga is turned away
    from the sun in the winter.
  • Seasonal climate
  • Long winter (6-7 months)
  • Summer is rainy, hot and short
  • Fall is the shortest season. Spring brings
    flowers and the frozen ponds melt.

Climate continued
  • Lowest temperature is -65F in the winter
  • Highest temperature is 70 F in the summer.
  • The taiga's average annual rainfall of 12 - 33
    inches (30 - 84 cm). Most of it falls in the
    summer as rain

Soil Type
  • Characterized as young and poor in nutrients
  • Caused by the cold, which slows the development
    of soil and plants' ability to use its nutrients.
  • Much humus and litter ? fallen leaves and moss
    remain on the ground for a long time which limits
    their contribution to the soil
  • Soils acidic ? acids from pine needles also
    strains the soil from having more nutrients.
    However, in clearings in the forest and in areas
    with more trees there are more herbs and berries

Common Vegetation
  • Coniferous trees
  • Spruce
  • Fir
  • Pine
  • Larch
  • Tamarack
  • Poor understory
  • Deciduous tress/shrubs
  • Alder
  • Birch
  • Aspen

Adaptations/Features of Plants
  • Conical shape
  • Promotes shedding of snow and prevents loss of
  • Needle-like leaves
  • Reduces surface area through which water can be
  • Have thick, waxy coating cuticle again to
    prevent water loss
  • Evergreen retention of foliage
  • Allows plant to photosynthesize as soon as
    sunlight is available, rather than waiting to
    grow leaves
  • Dark color
  • Helps the plants to absorb maximum sunlight

Animal Life
  • There are 85 species of mammals, 120 species of
    fish, and 32,000 species of insects
  • Some animals include mule, deer, moose, elk,
    mice, hares, squirrels, lynx, bears, foxes,
    fishers, marten, birds
  • Taiga has cold summers and warm winters, which of
    course is a challenging biome for reptiles and

Animal Life
  • Home to many large herbivorous mammals
  • Animals eat heavily during summer to gain fat for
    winter and have heavy layers of fur to insulate
    their bodies.
  • Also fur is dark in the winter and light in the
    summer which can help protect against predators
    (snowshoe hare)

How people have adapted to living/working in the
  • Very few people live in the taiga because of its
    cold climate
  • Most of the taiga is unpopulated, though there
    are a few large cities in the southern parts such
    as Moscow or Toronto

How people have adapted to living/working in the
taiga continued
  • Humans have adapted to working in the taiga by
    using the abundant resources it produces
  • Logging, mining, and hydroelectric development (a
    form of renewable energy where electrical power
    is produced by flowing/falling water)
  • These activities negatively impact the biome
  • Most of logging is done by clear-cutting ?
    regrowth of mature forests takes a long time
    because of climate and soil
  • Hydroelectricity seems beneficial, modifies and
    disrupts the environment

  • Opportunities
  • Limitations
  • Abundance of empty land
  • Lots of resources to use and exploit.
  • Can have peace and solitude and be by yourself
  • Few cities or other forms of civilization
  • Large amounts of snow and extreme weather
  • Difficult for plants to grow because of the thin
    and nutrient-poor soil

You should move to the Taiga because
  • In the summer months since ground is moist plant
    growth can be very rapid in this short time of
    3-4 months.
  • Lots of trees and other resources
  • If you want you can live alone and have peace and
  • However, there are also a few large cities if you
    prefer a more metropolitan lifestyle

Before moving, please consider
  • Harsh weather in the Taiga
  • Huge range of temperatures, from very cold for a
    long period of time to hot temperatures.
  • Steady amounts of precipitation (in small
    amounts) throughout the year but in the winter
    it is only snow.
  • Due to the permafrost, you cannot grow many types
    of crops because of the frozen soil
