+
Climate
• A tropical dry and wet climate.
• Although it is located at tropical latitudes it is much drier than most tropical forest.
• 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. :/
Location • Widespread on the continent of Africa• India• Northern parts of South America • Australia
Abiotic Factors
• Fires from seasonal lightning• Seasonal rainfall• Times of drought• Times of great rain• High temperatures• Compact soil
Biotic Factors
• Vegetation (tall grasses, shrubs, and trees)• Animals and their behaviors as well.
Tropical Savanna: Animals
• Wildebeest• Warthogs• Elephants• Zebras• Rhinos• Gazelles• Hyenas• Cheetahs
Animals continued…
• Lions• Leopards• Ostrich• Mousebirds• Starlings• Weavers• And more…
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.
Tropical Savanna: Plants• Most common are…
– Acacia tree– Baobab tree
• Grasses can grow 6 to 9 feet tall.
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
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
