Facts
• The temperate deciduous forest is a biome that is
always changing in result of the seasons but it never
gets too hot or too cold.
• This biome is one of the only biomes to have four
distinct seasons: summer, fall, winter, and spring.
• In this biome, the leaves of the plants change color in
autumn, fall in the winter, and grow again in the
spring.
• The latitude range anywhere
from 23 degrees north to 38
degrees south

Locations
• Temperate deciduous forests can be found in the
eastern half of North America, and the middle of
Europe. There are also many of these forests in
southwest Russia, Japan, eastern China, South
America, New Zealand, and southeastern Australia

The average temperature is
roughly 50 degrees F.
The average amount of
rainfall is about 30 to 60
inches of rain each year.
The soils found in these forests
are deep well drained and
contain clay, sand, silt and
lots more of organic matter.
The soils found in the
Deciduous Forest are the
most productive in the world.
Alfisols and Ultisols are the
two out of the 12 soils that
are classified to be in the
Deciduous Forest.
Common Plant Forms

Oaks are one of the dominant tree species in the
deciduous forest, at least in North America. Many of the
dominant species produce large seeds.

Other important trees include hickories and walnuts.

Wildflowers are also common in the forest, although
they need some unusual strategies to survive on the
forest floor. Many bloom early in the spring, and may
shed their leaves and remain underground through the
remainder of the summer.


Most mammals of
the forests hibernate
during the winter
months.
Many species of
birds migrate to
warmer places
where they can find
food more easily.

Environmental issues:
Limiting factors:
 Invasive insects- the emerald ash
borer insect has killed tens of
millions ash trees in North America.
 pets
 Deforestation and fragmentationcreations of small patches of roads,
towns, and railways.
 Animal overgrazing-reduction of
hunting. Deer eat the leafy shoots
of newly forming trees and lower
canopy shrubs.
 Invasive plants- Tree of Heaven
which spreads quickly into forests
edges and prevents forest growth

 Sunlight
