  • 1. Angola Africa Botswana Madagascar Kenya India Nambia South SouthAmerica.Africa And some Tanzania parts of Zimbabwe Australia

2. Tropical or subtropical grasslands ranging from dry scrubland to wet, open woodland. They are found in awideband on either side of the equator often bordering a rainforest. Appearance - Large open area of rolling grasslands with scattered and isolated trees. Also known as the tropical grasslands because they are usually found between tropical rain forests and deserts. 3. Baobab Trees Found in African savanna. Survive in hot-dry conditions. Longest living species with some datingback 6,000 years. They store water in hollow parts of thetrunk. Can grow 75 ft. tall with a 60 ft. girth. The leaves and fruits are highlynutritious, sometimes called monkeyfruit. Monkey Fruit can contain more vitaminC than an orange and more calcium thanmilk. 4. Acacia Trees They have small leaves, viciousthorns, and exude nectar to feeddangerous rodents that live on thetree. When animals eat the leaves, itpumps chemicals into the leaves togive them a bad taste. It releases a gas that signals othertree to fill their leaves with thechemical. 5. Kangaroo Paws Tiny wooly hairs on its flowers. The hairs make it taste weird topredators. The hairs also hold on to water. Has a sturdy stem for itspollinators to perch on. 6. Bermuda Grass Grows in areas with lots offrequent disturbances. Called Bermuda because itoriginated from the BermudaIslands. Uses rhizomes, runners, and seeds. During droughts the upper partof the plant dies off, while theplant continues to grow throughthe rhizomes. 7. Red Oat Grass Can grow as large as 3 ft. tall. Blades are a blue-green color duringits most productive season. Once dormant, it fades into a yellowcolor and its seed pods are flattened. Extremely tough but has littlenutritional value for the animals thateat it. 8. Prickly Pears Thick, waxy like skin. Flexible stem - moves, processes andstores water, nutrient solutions, andenergizing photosynthetic products. Shallow roots to reach waterquicker. Spikey leaves to protect itself frompredators. 9. Przewalskis Horse Endangered - were once hunted for theirmeat and lost much of their naturalhabitat to grazing domestic animals. Good all round senses of sight, hearing andsmell, essential in detecting predators. Wide row of incisor teeth to enable thelargest possible mouthfuls of grass, whichis essential as grass has little nutritionalvalue so horses must spend a lot of thetime eating. The ability to attain speeds of up to40mph and to sustain this for long periods Short, muscular body. Smaller than mostmakes them difficult for predators todomesticated horses. Redish-brown body,catch.white-beige stomach and muzzle. 10. Spotted Hyena Endangered - due to habitat loss,killings by farmers and entrapment. Communicates with others using aseries of calls, some of which are toohigh for humans to hear. Very powerful jaws that can crunchlarge bones, tusks, and horns. Thisability is key for hyenas that scavengefrom the kills of lions and other bigDog-like with short spotted fur. Females arecats.larger and stronger, therefore dominant. 11. Vulturine Guinea Fowl Currently Not Endangered. Able to live for a long time without water,obtaining all the necessary fluid from itsfood. Very strong fliers. Roost in trees at night to protectthemselves from predators on the ground.Large Bird with a round body and small head. 12. Congo African Grey Parrot Endangered - Poaching and habitatdestruction. Very strong. Can bite with their strong pointedbeak and scratch with their claws. Highly intelligent. Produce a powder on there feathers toclean and protect them , this powderalso makes them waterproof. About 13 in. long, with light grey feathers,cherry red tails, and an all black beak. 13. African Bullfrog Currently Not Endangered. Carnivorous. Quite aggressive and has sharp teethso its bite can be quite serious. The male bullfrog will alsoaggressively defend his eggs if ananimal or a human should approach. Very large, dull green in color. Can weight up to 4.4 pounds. Male is larger than femaleunlike many other frog species. 14. African Reed Frogs Endangered habitat destruction. These frogs are tree-hugging frogs, thishelps protect them from predators on theground. Small suction cups located at the end of eachtoe are what enables these frogs to climb. Brightly colored but not toxic. Commonly confused with the poison arrowfrog. They survive the savanna by adjusting theirThere are over 150 species, they vary inwater economy and metabolism. pattern and color. They grow to be about 1 Can change color dramatically depending on inch longthe environmental conditions. 15. Boomslang Currently Not Endangered. Well camouflaged and strikeswithout warning. Delivers potent hemotoxic venom toits victim through large, deeplygrooved folded fangs. Prefers aerial positioning in treetop and shrub cover. Lays eggs in the hollow of trees,Can grow up to 6 feet in length. Colors rangeprotecting them from mostto green brown and blue. Large eyes with eggpredators.shaped head. 16. Gharial Endangered. habitat destruction. 106 to 110 very sharp teeth for catchingfish. Well-developed tail for swimming inwater. Rear feet have extensive webbing, alsofor swimming. They leave the water only to bask andShort legs and long, thin snout with razornest on sandbanks.sharp teeth. 17. Dung Beetle Currently Not Endanger. Very important to the ecosystem. Survive on feces. Has good sense of smell used to findfood. Considered sacred to the ancientEgyptians. They navigate by using the moon. Small, egg shaped, hard, black bodies. . 18. Termites Currently Not Endangered. Colonies appear as grassy mounds thatcan reach 32-1/2 feet in diameter. Mounds have a positive influence on localanimal and plant activity. During natural fires in the savanna,termites fly until it has passed. All members of the colony have certainjobs to do and are specially design to dothat job. Tiny, blind creatures less than 1/10th of an inch in size. 19. Large areas of the savanna are clearedout for crops and farming. Removing thetrees also removes competition betweenthe grasses for water, this increasesthe pasture production and foodquality.To correct the damage, National Parks have been established to preserve the savanna lands (ex. Kruger National Park, KalahariGemsbok National Park, and many others. 20. Many of the animals of the savanna were killed for theirmeat (Przewalskis horse), fur (leopards), or for theirtusks (elephants). This caused many animals to becomeendangered or extinct. -To correct the damage, laws have been created to helpprotect these animals from endangerment andextinction. They are also raised and bred in captivity to give them a better chance of repopulation. 21. Human induced climate changes (globalwarming) greatly effects all biomes. Itcauses un-natural changes in theenvironments and effects the animalsand organisms way of life in anegative way. It changes theirclimates.-To fix the damages, many humans are trying to go green . 22. Biodiversity The savanna ishome to many different animalsMigration Tanzania is where oneand organisms. Without thisof the biggest migrations everbiome, their survival might beoccurs; The Serengeti. And it allimpossible. The climate andhappens on the savanna. Its hereenvironment they need is specificthat the animals graze and restto their adaptations.before finishing their journeys.Crops Many people live off ofthe savanna lands. It provides foodand other necessities to humans. 23. http://www.blueplanetbiomes.org/savanna_plant_page.htmhttp://www.blueplanetbiomes.org/savanna.htmhttp://www.globalanimal.org/2011/06/20/endangered-przewalski-horses-reintroduced-to-wild/42808/http://library.thinkquest.org/26634/text/grass/impact.htmhttp://www.plantzafrica.com/vegetation/savanna.htm 24.
