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.
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.
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.
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.
