Topical Savanna Biome Darrell Render, Jr. And Ajalyn Ramos
Location of Biome African Savanna biome is a tropical grassland that takes up almost half of Africa.
Climate • Very long dry season-Winter • Very wet season-Summer • From May-November, it gets 15-25 inches of rain per month • Dry season gets only about 4 inches of rain, occurs from October-March • surface water from the rain is quickly absorbed into the ground because the soil is extremely porous. Lightning frequently ignites the brown, dry grasses that cover the savannah.
Animal Adaptions • Rainy Season-birds, insects, and both large and small mammals thrive in the savannah • Dry Season-The ability to fly or to run fast enables most birds and large mammals to escape the flames. small burrowing animals frequently survive the fire by digging beneath the soil and remaining there until the flames pass by them.
Animals • Wildebeest • warthogs • elephants • zebras • rhinos • gazelles • hyenas • cheetahs, lions, leopards • Mousebirds
Soil • Poor soil because of the dry season • When it’s rainy season, the soil is very fertile
Jackalberry Tree • Genus: Diospyrus • Species: mespiliformis • Parts used: bard, leaves, twigs, and roots • Prefers moist soil/rocky soils • Grows well in the red loams
Whistling Thorn • Genus: Acacia • Species: dreparalobium • It protects itself with a pair of long thorns up to 3 inches long • Has developed serval ways to survive the severley hot and dry climate • The tree must find ways to conserve moisture
Kangaroo Paw • Genus: Anigozanthos • Species: manglessi • Adaption: have tiny wooly hairs on its flowers that help make it taste weird to predators so they wont eat it. The hairs also help by holding on to water because it grows in a dry climate.
Endangered Species • The black rhino is the most endangered in the world .. Fewer 3,200 in 2001. they kill them for their horns • The african elephant: their hunted for their tusk, meat, and skin. • The lion population is holding steady, but their still endangered.
Threats • Overgrazing and cultivation of marginal soils already low in plant nutrients are destroying what were once rich farming lands. • pests, disease, and drought cause many problems for the soil. • Fires during dry season • Not a balanced savannah because of usage by humans
