Acacia Savannah characteristics
●Contains tropical and desert spots
●Not enough rain to support forests
●Located on either side of equator
●On edges of tropical rainforests
●It is important because of it’s abundance of
life

Description
•It is found in eastern africa
•Distinct grasslands and savannah large
drought
• Great numbers of migrating animals
•Is the only region where the grey chested
spurfowl lives
•Large no hunting areas

Desertification
•Causing livestock and humans to relocate
•Trees shrubs etc. are vanishing from this
biome.
•Due to other organisms disappearing they to
must leave

Desertification factors
some underlying factors are that
drought
lack of forest
and the planting of inappropriate agricultural

Combating desertification
•Plant proper crops
•Plant trees and other life
•In windy regions use tree fences to help
plants survive and row
•use water efficiently

Other issues
•Lack of biodiversity plant wise
•Drought
•Poaching

The Black RhinocerosAbout 1.6m tall
Two horns only
Smaller than white rhinos
Have hooked lips for eating
No color difference than the white rhino

Its Role
The Black rhino helps shape the landscape
The Black rhino eats lots of grass and bushes
a day
Sadly it gets eaten by large wild cats
It places as a primary consumer
The Savannas wouldn’t look the way they do
now

Endangered status
Mainly poaching is making this animal go
extinct

Population
The size of the population: about 5,000
(1993)
Life span is from 40-50 years
reproduction rate:1 calve every 2.5-3.5 years
how this affects the population

What is being done
WWF is expanding existing protected areas
and improving their management
Establishing new protected areas
Improving security

Invasive Species
Bigheaded Ant
![Page 18: East African Acacia Savannas - Science Rules!nilssonscience.weebly.com/uploads/4/4/9/...savanna.pdf · •Distinct grasslands and savannah large drought • Great numbers of migrating](https://reader033.vdocument.in/reader033/viewer/2022050119/5f4f79418ee6b3051d5fb16e/html5/thumbnails/18.jpg)
Introduction to Bigheaded Ant
Scientific name- Pheidole megacephala
(Fabricius)
Red and brown
Larger sized head
Mainly nest in rotting stumps.
2 antennas
6 legs
![Page 19: East African Acacia Savannas - Science Rules!nilssonscience.weebly.com/uploads/4/4/9/...savanna.pdf · •Distinct grasslands and savannah large drought • Great numbers of migrating](https://reader033.vdocument.in/reader033/viewer/2022050119/5f4f79418ee6b3051d5fb16e/html5/thumbnails/19.jpg)
Food Web Positioning
Primary consumer
Eats sugary substances (Both habitats)
Also eats smaller insects (African Savannah)
Spiders eat the ant (Both habitats)
Anteaters (Native habitats)
Flies (Both habitats

Problem
The big headed ant can cause damage by
destroying structures and causing debris.
Plant mutualism with the Big-headed ant,
increases elephant damage to savannah
trees.
The ant hides in the tree while the elephant
breaks down the tree to get them.
