The Climate
• The annual precipitation of the tropical
savanna is 20 - 40 inches.
• The average temperature is 78F
• Both the dry, and wet seasons last 5-6
months each.
Abiotic Factors
• The factors that can affect the tropical
savanna and its organisms living in it
are unseasonably warm temperatures,
seasonal rainfall which can be too high
or low which can cause floods or
droughts, and fires that can be set by
lightning can be harmful to the
organisms.
Dominant Plants
• The dominant plants in the tropical
savanna is fire resistant and drought
tolerant shrubs, and highly elevated
grass. The trees are isolated along with
the shrubs. Since the trees are isolated,
the tropical savanna is an open area
filled with the tall grass.
Dominant Wildlife
• The dominant animals in the tropical
savanna are the hoofed mammals
which include antelope, buffalo,
wildebeest, zebra, rhinos, giraffes, and
elephants which are the herbivores. The
dominant mammal carnivores are lions,
cheetahs, leopards, and hyenas.
Geographical Distribution
• The tropical savanna is located in
northern and east central South
America, central and southern Africa,
the Indian Peninsula in Asia, and
scattered throughout Australia.
Impact of human Activity
Human had caused a lot of changes to the landscape
of and the animals in grasslands since a long time ago.
Large areas of grassland have been turned into
farmlands for growing crops and for rearing cattle.
Sometimes, fires are started by human and they spread
quickly through grasses and damage the soils.
Moreover, a large number of animals have been hunted
for their valuable body parts. For example, elephants
were shot for their tusks, lions were killed for their fur
and bison were hunted for their meats.
