Location


Temperate deciduous forests are located in
the mid-latitude areas which means that
they are found between the polar regions
and the tropics.
Eastern United States, Canada, Europe,
China, and Japan are all locations where
the deciduous forests exists.
Biome Map
Abiotic Factors
The deciduous forest regions are exposed to warm and cold air masses, which cause
this area to have four seasons. This is caused by the position of the sun and rotation of
the Earth.
The temperature varies widely from season to season with cold winters and hot, wet
summers.
The average yearly temperature is about 10°C.
The areas in which deciduous forests are located get about 750 to 1,500 mm of
precipitation spread fairly evenly throughout the year.

Biotic Factors

Many different kinds of
trees, shrubs, and herbs
grow in the deciduous
forests. Most of the trees
are broadleaf trees. There
are also several different
kinds of plants that live on
the shady forest floor
where only small amounts
of sunlight get through.
Plant Species



There are many different plant
species in the temperate
deciduous forest.
They appear in one of the five
zones:
Tree Stratum zone – contains trees
such as oak, beech, sweet gum,
chestnut, hickory, basswood, and
walnut.
Small Tree and Sapling zone –
young and short trees are in this
zone.
Shrub zone – includes
rhododendrons, azaleas, mountain
laurel, and huckleberries.


Herb zone – contains short herbal plants.
Ground zone – this final zone contains club mosses,
true mosses, and lichen.
Adaptations

During the fall, trees change color and then
lose their leaves. This is in preparation for
the winter season. Because it gets so cold,
the trees have adapted to the winter by
going into a period of dormancy or sleep.
They also have thick bark to protect them
from the cold weather. Trees flower and
grow during the spring and summer
growing season.
