3. Tropical or subtropical grasslands ranging from dry
scrubland to wet, open woodland. They are found in a
wideband on either side of the equator often bordering a
rainforest.
• Appearance -
– Large open area of rolling grasslands with scattered and
isolated trees.
– Also known as the tropical grasslands because they are
usually found between tropical rain forests and deserts.

5. Baobab Trees –
• Found in African savanna.
• Survive in hot-dry conditions.
• Longest living species with some dating
back 6,000 years.
• They store water in hollow parts of the
trunk.
• Can grow 75 ft. tall with a 60 ft. girth.
• The leaves and fruits are highly
nutritious, sometimes called monkey
fruit.
• Monkey Fruit can contain more vitamin
C than an orange and more calcium than
milk.
6. Acacia Trees –
• They have small leaves, vicious
thorns, and exude nectar to feed
dangerous rodents that live on the
tree.
• When animals eat the leaves, it
pumps chemicals into the leaves to
give them a bad taste.
• It releases a gas that signals other
tree to fill their leaves with the
chemical.
7. Kangaroo Paws –
• Tiny wooly hairs on its flowers.
• The hairs make it taste weird to
predators.
• The hairs also hold on to water.
• Has a sturdy stem for its
pollinators to perch on.
8. Bermuda Grass –
• Grows in areas with lots of
frequent disturbances.
• Called Bermuda because it
originated from the Bermuda
Islands.
• Uses rhizomes, runners, and seeds.
• During droughts the upper part
of the plant dies off, while the
plant continues to grow through
the rhizomes.
9. Red Oat Grass –
• Can grow as large as 3 ft. tall.
• Blades are a blue-green color during
its most productive season.
• Once dormant, it fades into a yellow
color and its seed pods are flattened.
• Extremely tough but has little
nutritional value for the animals that
eat it.
10. Prickly Pears –
• Thick, waxy like skin.
• Flexible stem - moves, processes and
stores water, nutrient solutions, and
energizing photosynthetic products.
• Shallow roots to reach water
quicker.
• Spikey leaves to protect itself from
predators.
11. Przewalski’s Horse –
• Endangered - were once hunted for their
meat and lost much of their natural
habitat to grazing domestic animals.
• Good all round senses of sight, hearing and
smell, essential in detecting predators.
• Wide row of incisor teeth to enable the
largest possible mouthfuls of grass, which
is essential as grass has little nutritional
value so horses must spend a lot of the
time eating.
• The ability to attain speeds of up to
40mph and to sustain this for long periods Short, muscular body. Smaller than most
makes them difficult for predators to domesticated horses. Redish-brown body,
catch. white-beige stomach and muzzle.
12. Spotted Hyena –
• Endangered - due to habitat loss,
killings by farmers and entrapment.
• Communicates with others using a
series of calls, some of which are too
high for humans to hear.
• Very powerful jaws that can crunch
large bones, tusks, and horns. This
ability is key for hyenas that scavenge
from the kills of lions and other big
Dog-like with short spotted fur. Females are
cats.
larger and stronger, therefore dominant.
13. Vulturine Guinea Fowl–
• Currently Not Endangered.
• Able to live for a long time without water,
obtaining all the necessary fluid from its
food.
• Very strong fliers.
• Roost in trees at night to protect
themselves from predators on the ground.
Large Bird with a round body and
small head.
14. Congo African Grey Parrot –
• Endangered - Poaching and habitat
destruction.
• Very strong.
• Can bite with their strong pointed
beak and scratch with their claws.
• Highly intelligent.
• Produce a powder on there feathers to
clean and protect them , this powder
also makes them waterproof. About 13 in. long, with light grey feathers,
cherry red tails, and an all black beak.
15. African Bullfrog –
• Currently Not Endangered.
• Carnivorous.
• Quite aggressive and has sharp teeth
so its bite can be quite serious.
• The male bullfrog will also
aggressively defend his eggs if an
animal or a human should approach.
Very large, dull green in color. Can weight up
to 4.4 pounds. Male is larger than female
unlike many other frog species.
16. African Reed Frogs–
• Endangered – habitat destruction.
• These frogs are tree-hugging frogs, this
helps protect them from predators on the
ground.
• Small suction cups located at the end of each
toe are what enables these frogs to climb.
• Brightly colored but not toxic.
• Commonly confused with the poison arrow
frog.
• They survive the savanna by adjusting their There are over 150 species, they vary in
water economy and metabolism. pattern and color. They grow to be about 1
• Can change color dramatically depending on inch long
the environmental conditions.
17. Boomslang –
• Currently Not Endangered.
• Well camouflaged and strikes
without warning.
• Delivers potent hemotoxic venom to
its victim through large, deeply
grooved folded fangs.
• Prefers aerial positioning in tree
top and shrub cover.
• Lays eggs in the hollow of trees, Can grow up to 6 feet in length. Colors range
protecting them from most to green brown and blue. Large eyes with egg
predators. shaped head.
18. Gharial –
• Endangered. – habitat destruction.
• 106 to 110 very sharp teeth for catching
fish.
• Well-developed tail for swimming in
water.
• Rear feet have extensive webbing, also
for swimming.
• They leave the water only to bask and Short legs and long, thin snout with razor
nest on sandbanks. sharp teeth.
19. Dung Beetle–
• Currently Not Endanger.
• Very important to the ecosystem.
• Survive on feces.
• Has good sense of smell used to find
food.
• Considered sacred to the ancient
Egyptians.
• They navigate by using the moon.
Small, egg shaped, hard, black bodies. .
20. Termites –
• Currently Not Endangered.
• Colonies appear as grassy mounds that
can reach 32-1/2 feet in diameter.
• Mounds have a positive influence on local
animal and plant activity.
• During natural fires in the savanna,
termites fly until it has passed.
• All members of the colony have certain
jobs to do and are specially design to do
that job. Tiny, blind creatures less than 1/10th of
an inch in size.

22. Large areas of the savanna are cleared
out for crops and farming. Removing the
trees also removes competition between
the grasses for water, this increases
the pasture production and food
quality.
–To correct the damage, National
Parks have been established to
preserve the savanna lands (ex.
Kruger National Park, Kalahari
Gemsbok National Park, and many
others.
23. Many of the animals of the savanna were killed for their
meat (Przewalski's horse), fur (leopards), or for their
tusks (elephants). This caused many animals to become
endangered or extinct.
-To correct the damage, laws have been created to help
protect these animals from endangerment and
extinction. They are also raised and bred in captivity
to give them a better chance of repopulation.
24. Human induced climate changes (global
warming) greatly effects all biomes. It
causes un-natural changes in the
environments and effects the animals
and organisms way of life in a
negative way. It changes their
climates.
-To fix the damages, many humans
are trying to “go green” .
