Ch. 9 Forest Biomes
Located in Northern
Hemisphere
Located in sub arctic
regions of North
America, Europe, and
Asia
 Warm summers (2 to 5
months)
 Long winters, cold and
dry




Precipitation is rain in
summer and snow in
winter
 40 to 200 cm of
precipitation a year
 Coniferous means
“cone bearing” which
means trees that
produce seed cones
conifers have leaves
called needles which
are waxy covered
Forest Biomes
these needles help tree
conserve water
most conifers are
evergreen meaning that
they do not drop their
needles
pines, hemlocks, fir,
spruce and cedar
 these trees grow in dense
stands which blocks a lot
of sunlight from getting to
the ground
Forest Biomes
The snow acts like a
blanket and prevents
the floor of the forest
from becoming
permafrost. This
insulates the roots of
the trees and allows
small animals (like
mice) to survive under
the snow.
Forest Biomes
The soil of the
coniferous forest is poor
because the trees
shade the forest floor.
Few plants grow here
because the fallen
needles make the soil
acidic. This makes the
forest floor lack organic
matter.
Forest Plants
Ferns
Lichens
Mosses
Small Herbivores
 eat
seeds
mice,squirrels
jays, other
rodents and
birds
Large Herbivores
Feed on
plants
and bark
 Moose, elk,
beaver,snowshoe hares
Large Predators
eat the
herbivores
grizzly
bears,
wolves,
lynxes
All these animals have
adaptations to allow them to
survive the winters.
They migrate, hibernate, or live
under the snow. Some have
thick body coverings
