TRITON INDUSTRIES PRESENTS:
A DAY IN THE
TROPICAL
SAVANNA
AFRICA, AUSTRALIA, ASIA, SOUTH AMERICA, NORTH
AMERICA
WE ARE UNIQUE
 Dominated by grasses and other herbaceous
plants
 Shrub and tree-sized woody plants
 Support a great seasonal abundance of large,
migratory mammals, as well as substantial
populations of resident animals
 In Australia there are many species that are
found nowhere else in the world
ANIMALS AND PLANT ADAPTION
 Grasses keep a supply of nutrients and water in
the roots below the ground. As such, they can
survive fires that usually only affect the parts of
the plants above ground. Fire actually
replenishes the soil with nutrients, encouraging
plant growth. After a fire, the acacia tree can resprout from the root crown, which is located
under the ground and suffers no significant
damage from a fire
 Although elephants do migrate, they have a
physical adaptation that allows them to access
water that is not available to other animals.
Baobab trees store water in their large trunks.

PLANT AND ANIMAL
CHARACTERISTICS
 So many native plants because the tropics are generally
found to have more biodiversity in a given area than regions
in higher latitudes.
 The plants need to be able to survive the dry season and
drought in the savanna. Some store water and energy in
their roots, bulbs, or trunks. Others have roots that go deep
into the ground to reach the low water table.
 Animals that are highly adaptable can survive much better
than ones with a narrow niche
 Plants that can adapt to fire and rapidly changing
environment will survive well.
CLIMATE
 A tropical wet and dry climate predominates in areas covered by savanna
growth.
 Average monthly temperatures are at or above 64° F and annual precipitation
averages between 30 and 50 inches.
 For at least five months of the year, during the dry season, less than 4 inches
a month of rain is received.
 The dry season is associated with the low sun period.
 Savannas get all their rain in the summer months.
 During the distinct dry season of a savanna, most of the plants shrivel up and
die. Some rivers and streams dry up. Most of the animals migrate to find food.
 During the wet season all of the plants are lush and the rivers flow freely. The
animals migrate back to graze
 In the winter, it is usually about 68° to 78° F.
 In the summer the temperature ranges from 78° to 86° F.
 In a Savanna the temperature does not change a lot. its very gradual and not
drastic.
 annual precipitation of 10 to 30 inches (100 to 150 cm) of rain.
FEATURES OF
TROPICAL SAVANNA
 Tropical savannas are located in semi-arid to semi-humid
climate regions of subtropical and tropical latitudes
 A savanna is a rolling grassland scattered with shrubs and
isolated trees.
 Not enough rain falls on a savanna to support forests.
Also known as tropical grasslands.
 They are found in a wide band on either side of the
equator
 characterized by the trees being widely spaced so that the
canopy does not close.
 The open canopy allows sufficient light to reach the
ground to support the grass
SOIL AND VEGETATION
 The soils of the tropical savannas are a major determinant of
vegetation in the region
 Soil is essentially a scab-like crust which forms on rocks as
they decompose under the elements
 Soils formed from granites tend to be sandy and infertile, while
those formed from basalts will be more fertile and clayey
 Savannas are characterized by a continuous cover of
perennial grasses, often 3 to 6 feet tall at maturity.
 Furthermore, savannas may be distinguished according to the
dominant taxon in the tree layer: for example, palm savannas,
pine savannas, and acacia savannas.
A PROBLEM WE FACE
• Weeds are an environmental issue the Tropical Savanna
faces.
• Weeds are any plants that are out of place. In Australia, these
weeds are often not native species, although some can be if
they move away from their natural area. Once these weeds
invade they introduce diseases and insects that the native
plants are not used to. They can also out-compete native
plants for resources such as light, space, and food. Weeds are
one of the most serious environmental issues in Australia’s
tropical savannas today

TOURIST AND SEASONAL
INFORMATION
 The most popular time to visit is March through June, when
temperatures are mild, flowers are in bloom, and events are
happening everywhere.
 Visitors will find fewer crowds and lower prices during the summer
and winter months, but temperatures aren't as ideal. Fall can be a
favorable time to go, with a good balance of pleasant weather and
fewer visitors.
 Birding
 go on a wildlife safari
 view tribal life with a guide
 Bunge jumping
 ride elephants
 rafting
