•Average is at or above 64 degrees F.
•Rainfall- 50 to 150 cm (20 to 60 inches).
•All this rainfall can occur within weeks
•During the 5 month dry season less than 4
inches. :/

4. Location
•Widespread on the continent of Africa
•India
•Northern parts of South America
•Australia

5. Abiotic Factors
•Fires from seasonal lightning
•Seasonal rainfall
•Times of drought

•High temperatures
•Compact soil

6. Biotic Factors

9. Animal Adaptations
•During the dry season most birds and large mammals
migrate.
–Ex. Elephants migrate but they also have the physical strength
to tear open a tree and drink its water
–Ex. Small burrowing animals go to sleep kind of like bears.
•Lightning also causes fires which means animals need to fly
and run fast.
–Ex. Fork-tailed Drongos attracted. They feast on the fleeing
insects.
–Small burrowing animals dig deep under ground.

•Most common are…
–Acacia tree
–Baobab tree
•Grasses can grow 6
to 9 feet tall.

11. Tropical Savanna: Plants
•In order to survive the fires and droughts
plants:
–Grasses turn brown to limit water loss
–Store nutrients and moisture in roots
–Fire stimulates new growth and replenishes the
soil with nutrients

12.  and  Adaptations
•Baobab tree has adapted by:
–only producing leaves in the wet season.
–Leaves are tiny fingerlike clusters
–Their small size limits water loss
–Ability to store water in its large trunk
•Acacia tree has adapted by:
–Developing long tap roots that reach deep, ground water
sources
–Fire resistant
–Long sharp thorns to ward off animals
–And symbiotic relationship with stinging ants
