Triton Industries presents:
A Day in the
Tropical Savanna
Slide2Africa, Australia, Asia, South America, North America
Slide3We 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
Slide4Animals 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 re-sprout 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. The elephant's physical strength and anatomy allow it to tear open the trunk of the baobab tree and to suck the water from it. An adaptation used by small burrowing animals is to remain dormant during times of drought--much like bears do during the winter in other biome
Slide5Plant 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.
Slide6Climate
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.
Slide7Features 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.
A
lso
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
Slide8Soil 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
S
oils
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.
Slide9A 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

Slide12Tourist 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
.
