DECIDIOUS
FOREST BIOME
CREATED BY:
SOPHIA & KATIE
DECIDUOUS FOREST
• Deciduous forests grow at lower latitudes than
coniferous forests, and this latitude is called the
temperate zone.
• 90% of the human population lives in this biome.
• A deciduous tree is a tree that sheds its leaves
during a particular season of the year.
• They have three distinct vegetation layers.
• Highest layer: Canopy
• Middle layer: Understory
• Bottom layer: Humus
DECIDUOUS FOREST (CONT.)
• The animals adapt to the climate by hibernating in the
winter months and living off the land the rest of the year.
• Plants have adapted by leaning towards the sun in an
effort to soak up as much energy as possible because
they are continuously covered by the leaves of the trees
and the canopy.
• Deciduous means to fall off seasonally. This is
demonstrated when the leaves of the trees change colors
in the fall, fall off in the winter, slightly grow back in the
spring and are in full bloom during the summer.
ZONES
• Tree stratum
• Small tree and sapling
• Shrub zone
• Herb zone
• Ground zone
TREE STRATUM
• First zone, contains trees such as Oak, Beech, maple,
Chestnut, Hickory, Walnut, and Sweet Gum trees.
• Height of these trees range from 60-100 feet
• All of the canopy layer is made up of branches and trees
from the tree stratum zone.
• Because of their size, they provide homes for forest
plants and animals.
• This zone receives the most direct energy from the
sunlight.
SMALL TREE AND SAPLING
• Second Zone, short and young trees are located in this
zone.
• Even these small trees are able to adapt to the extremely
hot weather and freezing cold weather.
• Their leaves change with the seasons.
• Shedding the leaves help these small trees get rid of any
extra weight before the rainy fall season and the snowy
winter season.
SHRUB ZONE
• Third Zone, contains shrubs.
• A shrub a low, usually several stemmed woody plant.
• Some shrubs included in this zone are azaleas, mountain
laurel, and huckleberries.
HERB ZONE
• Fourth zone, this is where short and herbal plants grow.
• Herb layer is where all the leaves fall from the taller
plants and trees
• Even though it is not called the ground zone, the herb
zone actually touches the ground.
GROUND ZONE
•
•
•
•
Bottom most zone in the biome
Contains Lichens, club mosses, and true mosses.
The ground zone is where the soil is located.
Nutrients from all the fallen leaves get absorbed into the
ground zone.
• The ground zone gets the least amount of direct sunlight.
ANIMALS
•
•

Bears
Fox
Squirrel
Cardinal (many birds)
Raccoon
However, these animals are getting killed by poachers in
the forests and losing their homes because of
deforestation and construction.

Soil
●
●
●
Because there are so many layers of trees, leaves and
plants growing above the soil all of their nutrients
eventually get soaked into the soil, causing it to be very
fertile.
When the trees shed their leaves and when the plants
become dormant they fall onto the ground and get
distributed into the ground.
This is important for the soil because deciduous forests
can go for extended amounts of time without rain and in
extreme temperatures.
LOCATION
• Between the polar regions and the tropics
• Can be found primarily in the eastern part of the United
States, Canada, Russia, China, and Japan.
WEATHER
•
•
•
•
Average Temperature: 50 degrees
Average rainfall: 30-60 inches annually
4 distinct seasons. Winter-Spring-Summer-Fall
Animals and humans can identify the change of seasons
based on the temperature and what the leaves are doing.
Adaptations
● Bears
●
●
●
All bears in the deciduous forest have one key way of
adapting to the harsh winters and warm summers in
their habitats.
During the fall the bears begin to prepare themselves
for hibernation by filling up on as much food as possible
and collecting nuts and and others foods to store in their
caves that will give them nutrition while they hidden
away during the freezing temperatures of the winter
season.
During the summer bears adapt by being good hunters
and scavengers. They can easily catch smaller animals
and collect berries and leaves off the trees to help
sustain them in the summer.
Adaptations
● Oak Trees
This towering trees have a very obvious way of
adapting to the deciduous forest biome. They shed and
regrow their leaves seasonally
● The trees benefit from slowly watering the root system
for 24 hours once or twice per summer season.
● Oak Trees produce thick bark which enable it to
withstand forest fires.
