GRASSLANDS SAVANNA, AFRICA

CLIMATE IN THE SAVANNAS

10-30 inches of precipitation annually with the majority falling in summer months

Temperatures range from 68° to 78° F in the winter and 78° to 86° F in the summer

The Savannas dry season is the winter in which most of the plants die and the majority of animals migrate to find resources.

The wet season begins around May and plants start to prosper and animals migrate back

NET PRIMARY PRODUCTiVITY

The Savanna is located near the equator. Also because of the amount of area the Savanna covers, there is a lot of diversity in the plants and animals. They differ from other biomes because of the wet dry climate it does not experience all four seasons. Instead, it has heavy rain for a few months, then severe drought in which the area is susceptible to fires.

Soil Quality

The soil in the Savannas has little to no nutrients making it difficult for plants to grow or retain water. It is because of this the soil in the African Savannas can not be harvested for farming or other agriculture so it is not used for much of anything.

INVASIVE SPECIES

Invasive Fire Ants

Fire ants are native to South America and are thought to have come to the Savannas because of displacement caused by other ants. Another reason could be accidental human transport through travel.

Endangered

The Grevy Zebra is typically found in Somalia, Ethiopia, Eritrea, Djibouti, and Kenya. However, due to hunting (O in HIPPCO) and habitat loss, (H in HIPPCO) they are endangered and can now only be found on northern Kenya and southern Ethiopia.

Animals in the Savanna

Antelopes do well in this area because of their antelopes that give them an intimidating appearance to potential predators. Their fur also blends relatively well with the grass giving them a good camouflage. Last but not least, Antelopes travel in herds making it even harder to be attacked.

The African elephant does well in this area largely because of its trunk. The elephants trunk acts a nose, a hand, an extra foot, a signaling device and a tool for getting food, and water. It also allows the elephant to reach up to 23 feet in order to get food it may not be able to reach without it.

Leopards do well in this area because of all the Big Cats they are the strongest of the climbers and they are capable of killing prey larger than they are.

Plants in the Savanna

Elephant Grass does well in the Savanna because it grows along rivers where the soil is of better quality and reproduces through underground stems and shoots the roots to the surface.

The Senegal Acacia Tree is able to survive in the Savanna because of their long roots that are able to tap into deep water tables and also have thick bark to resist fires that happen regularly. They also often have mutualistic relationships with native ants to prevent being eaten by herbivores such as elephants.

Baobab trees can grow up to 100 feet and can store water in their tree trunk. They can then pull this water to use during the dry season.
