4. Climate
• The taiga biome has the
lowest temperatures year-
round after the tundra and
polar ice cap regions.
• The average temperature
in the winter season is -6
degrees Celsius.
• The Taiga experiences
relatively low precipitation
throughout the year.
5. SoilType
The soil in the Taiga is
nutrient-poor. In other
areas, a layer of bedrock
lies just beneath the soil.
Both permafrost and rock
prevent water from
draining from the top
layers of soil.This creates
shallow bogs known as
muskegs, which are
covered with moss, short
grass, and trees
8. Animalsinthe
Taiga
• MooseNiche:To eat aquatic and
terrestrial plants• Siberian tigerNiche:Top predator;
protect their cubs
• Lynx
Niche: Another top
predator
• Wild boarsNiche: Destroys plants,
mobile disease reservoirs
• Grey wolfNiche:Top predator,

• Brown bearNiche:Top predator
9. PlantsintheTaiga
• Black SpruceNiche: Used to
build houses, used
as Christmas trees
• Jack PineNiche: Used to
build houses &
make pulp for
paper
• White FirNiche: provides
food for squirrels,
porcupines
13. PrimaryProductivity
• Forest productivity in the middle
and northern taiga zones is
directly related to soil
temperature.Warmer soils
decompose organic matter more
quickly, releasing nutrients for
new plant growth and creating a
more productive site. Productive
forest types occupy warmer,
south-facing slopes and river
terraces, and less productive
dwarf or sparse forest occupies
the north-facing and basin sites.
• GPP: 1144.3 g /m2/yr
• NPP: 408 g/m2/yr
14. PrimarySuccession
• The pioneers came and
colonized the areas in the taiga
with fungi, lichen, grasses, and
wildflowers.These factors
started to react and recreated
the soil, which allowed small
vascular plants to grow. As the
plants grew and grew into
larger plants like trees, they
started to bring in animals
along into the biome.
15. SecondarySuccession
• As wildfires burn, they
destroy most of the land
in the Taiga ecosystem.
Plants still grow in the
areas in which the soil hasbeen disrupted-this is
called secondary
succession. After
wildfires, species like the
Jack Pine release seeds
into the soil.
16. HumanNegativeImpact
• The taiga isn’t affected by humans
as much as the other biomes. In
the taiga, logging is probably the
main source of destruction.
• Another industry that threatens
taiga species is hunting.The
Siberian tiger for example is
almost extinct due to poachers
hunting for its incredible coat.
Brown bears have seen a large
decline due to hunting and so
have many other large mammals
like the wolf, cougar, caribou,
moose etc.
17. HumanPositiveImpact
• Humans also have a positive
impact on the taiga. Some people
are trying to reduce the amount
of hunting so animals will
proceed to live in the taiga.
• The Forest Stewardship Council
is a logging organization that
ensures that the forest it logs
from are logged sustainably and
safely for the people who live in
the area and most certainly the
animals.• The World Wildlife Foundation is
also working endlessly to keep
the Siberian tiger from going
extinct.
