NORTHWESTERN CONIFEROUS
FOREST

distribution The Northwestern Coniferous
Forest is located in the Pacific northwest of
America. It ranges from the coast of northern
California to the southern coast of Alaska.

Biotic Factors

• Plant life Ample water and nutrients support
  lush, dense plant growth. Trees here are among
  the worlds tallest.
• Animal life Camouflage helps insects and
  ground-dwelling mammals avoid predation.

4
Abiotic Factors
Heat regulation Because of the dark coloration
of the coniferous trees, the small amounts of
sunlight are easily absorbed and that causes easy
heat regulation.
biomes acidic soils this is formed by the
rainfall dissolving sediments below the soil,
this causes the acidity of the soil. Soil Biome

Climate
The climate of the northwestern coniferous
forest is harshly cold in the winter and is warm
in the summer. Although it's warm in the summer
it's still cool all year round.

Precipitation
The mild rainning place, but it's hardly ever
to meet a heavy rain.It's usually wet and mild,
and the temperature will change a lot since
morning to the evening, about 10?.Actually ,it
will be pretty comfortable to live there, in this
kind of forest, there are many high pinetrees,you
can easily find this kind of forest with
mountains surroundings

The plant life in the thndra
Biotic Factors

• Mosses and other plants are low-growing to avoid
  damage from frequent strong winds.

The animals in the tundra

• Many animals migrate to avoid long harsh
  winters. Animals that live in the tundra
  year-round have adaptations such as natural
  antifreeze to limit heat loss.
