What is savanna?
Savannas are areas of open grassland
with very few trees. There are two types
of savannas, tropical and semi-tropical
savannas. Savannas are typically dry,
receiving less than 30 inches of rain on
average per year. The lack of water makes
savannas a difficult place for tall plants
such as trees to grow.

climate
It is usually cooler during the dry season by a
few degrees. Because it is in the tropical
latitudes that is still hot enough. The savanna
climate has a temperature range of 68° to 86° F
(20° - 30° C). In the winter, it is usually about
68° to 78° F (20° - 25° C). In the summer the
temperature ranges from 78° to 86° F (25° - 30°
C). In a Savanna the temperature does not
change a lot. When it does, its very gradual and

Wild dog adaptation. They have long slender legs to help aid
in tiring out their prey, they have great eyesight to help
them hunt during dusk and dawn, they also have strong
teeth so that they can bite through bone.

adaptations of a mongoose are that it has a strong jaw to
easily kill its prey, it has loose dense fur so that when a
snake bites it the venom only goes onto the fur and not into
the blood stream, it has strong front paws to help it break
eggs on rocks and that it has strong eye sight to help it hunt
and see predators in the dark.

A baboon's adaptations are that they have sharp claws to
fight off predators. They also have allot of fur around their
neck to keep them warm in cold temperatures. They also
have cheek pouches on their cheeks to store food.

Emus have a unique defense capability: when running at top
speed, the structure of their feet enables them to make
sudden 180-degree turns which not even a small cat can do.
Emus have strong endurance, being able to run at a steady,
loping pace for a long time.
When food is plentiful, emus can store extra fat, which they
may then rely on as they move on to a new food source.
Emus are effective swimmers.
Emus have three toes, unlike the ostrich, which has only
two. Having three toes equips the emu more efficiently for
running.
elephant Grass in the savanna is very bitter and sharp which
often puts animals off eating it.
Also in the wet season the grass is green and grows very
fast. However when it is the dry season the grass turns
brown and the chloroplasts inside the plant cells are pulled
down towards the roots of the grass.

Eucalyptus trees are also sometimes known as gum trees
because of the amount of sticky, gum-like sap that they have
in their trunks. This gum or sap is the product of vascular
tissue that transports substances such as water, sugars,
hormones, and minerals all throughout the plant.
they can survive on little or no water during drought

The baobab tree has adapted to the savanna biome by only
producing leaves during the wet season. When leaves do
grow, they are in tiny finger-like clusters. The small size of
the leaves helps limit water loss. Another adaptation that
enables the baobab tree to survive the long months of
drought is its ability to store water in its large trunk.

The acacia tree can survive drought conditions because it
has developed long tap roots that can reach deep, ground
water sources. It is also fire resistant. Some varieties report
from the root crown when the above ground portion of the
tree is damaged by fire. Fire is not the only hazard faced by
the acacia tree.

Abiotic factors
There are only a couple abiotic factors in the savanna that you can really
recognize.
One is fire. Fire is the most important abiotic factor to the savanna.
without the constant fires a tropical savanna could turn into a tropical
forest!
Another abiotic factor is soil. There really isn't much to say about the soil
except that it is real important to plants and the animals that eat the
plants
Air and water are the two last abiotic factors in the savanna. Everybody
knows the importance of air to any biome. Without it survival would be
impossible. Water is just as important. During the summer or dry season
there really isn't a lot of water .Trees store water during the wet season
so they have water during the dry season. Just like air, without water the
chances of living are very slim.

During the rainy season, birds, insects, and both large and small
mammals thrive in the savannah, but the rainy season only lasts 6 to 8
months. During the dry season, surface water from the rain is quickly
absorbed into the ground because the soil is extremely porous.
Consequently, most birds and many of the large mammals migrate
during the dry season in search of water. Because drought conditions
are sometimes localized, the migration may be just to another area
within the savannah. When drought conditions exist for a long time
and over a wide area, the animals may migrate to another biome until
the rainy season begins again.

How do humans affect the savanna?
The Savanna, being a grassland scattered with trees
and a large diversity of animals, has some threats to
it brought on by humans. The human effect has
created many threats such as overgrazing, poaching,
and clearing of the land for crops and buildings.
Humans affect the Savannah by grazing, timber
harvesting, and the burning of wood. They also
interrupt the cycle of fruit and plant growth by
collecting fruits and seeds that can feed other
mammals.

An example for people living in the savanna is the Masai tribes that live in East
Africa. The Masai people practise nomadic cattle herding and move seasonally
to find places with more moisture. However, they still have to face a lot of
problems such as soil erosion caused by overgrazing and diseases spreaded by
insects.

Another example is the Australian that practises extensive cattle farming
in Australia. As the cattle are affected by the poor grasses, diseases and
pests, the cattle are sent to better lands for fattening.
• They are bad because the overgrazing damage
the floor and leads to bad planting in the
future.
How could we make the savanna
better for the future?
To protect the Savanna in the future humans can
stop deforesting the environment, and especially
stop the poaching of all animals that in habit the
