Savanna presentation 1 26-12

  1. 1. • Angola • Africa• Botswana • Madagascar• Kenya • India• Nambia • South• South America. Africa • And some• Tanzania parts of• Zimbabwe Australia
  2. 2. Tropical or subtropical grasslands ranging from dry scrubland to wet, open woodland. They are found in a wideband 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. 3. Baobab Trees –• Found in African savanna.• Survive in hot-dry conditions.• Longest living species with some dating back 6,000 years.• They store water in hollow parts of the trunk.• Can grow 75 ft. tall with a 60 ft. girth.• The leaves and fruits are highly nutritious, sometimes called monkey fruit.• Monkey Fruit can contain more vitamin C than an orange and more calcium than milk.
  4. 4. Acacia Trees –• They have small leaves, vicious thorns, and exude nectar to feed dangerous rodents that live on the tree.• When animals eat the leaves, it pumps chemicals into the leaves to give them a bad taste.• It releases a gas that signals other tree to fill their leaves with the chemical.
  5. 5. Kangaroo Paws –• Tiny wooly hairs on its flowers.• The hairs make it taste weird to predators.• The hairs also hold on to water.• Has a sturdy stem for its pollinators to perch on.
  6. 6. Bermuda Grass –• Grows in areas with lots of frequent disturbances.• Called Bermuda because it originated from the Bermuda Islands.• Uses rhizomes, runners, and seeds.• During droughts the upper part of the plant dies off, while the plant continues to grow through the rhizomes.
  7. 7. Red Oat Grass –• Can grow as large as 3 ft. tall.• Blades are a blue-green color during its most productive season.• Once dormant, it fades into a yellow color and its seed pods are flattened.• Extremely tough but has little nutritional value for the animals that eat it.
  8. 8. Prickly Pears –• Thick, waxy like skin.• Flexible stem - moves, processes and stores water, nutrient solutions, and energizing photosynthetic products.• Shallow roots to reach water quicker.• Spikey leaves to protect itself from predators.
  9. 9. Przewalski’s Horse –• Endangered - were once hunted for their meat and lost much of their natural habitat to grazing domestic animals.• Good all round senses of sight, hearing and smell, essential in detecting predators.• Wide row of incisor teeth to enable the largest possible mouthfuls of grass, which is essential as grass has little nutritional value so horses must spend a lot of the time eating.• The ability to attain speeds of up to 40mph and to sustain this for long periods Short, muscular body. Smaller than most makes them difficult for predators to domesticated horses. Redish-brown catch. body, white-beige stomach and muzzle.
  10. 10. Spotted Hyena –• Endangered - due to habitat loss, killings by farmers and entrapment.• Communicates with others using a series of calls, some of which are too high for humans to hear.• Very powerful jaws that can crunch large bones, tusks, and horns. This ability is key for hyenas that scavenge from the kills of lions and other big Dog-like with short spotted fur. Females are cats. larger and stronger, therefore dominant.
  11. 11. Vulturine Guinea Fowl–• Currently Not Endangered.• Able to live for a long time without water, obtaining all the necessary fluid from its food.• Very strong fliers.• Roost in trees at night to protect themselves from predators on the ground. Large Bird with a round body and small head.
  12. 12. Congo African Grey Parrot –• Endangered - Poaching and habitat destruction.• Very strong.• Can bite with their strong pointed beak and scratch with their claws.• Highly intelligent.• Produce a powder on there feathers to clean and protect them , this powder also makes them waterproof. About 13 in. long, with light grey feathers, cherry red tails, and an all black beak.
  13. 13. African Bullfrog –• Currently Not Endangered.• Carnivorous.• Quite aggressive and has sharp teeth so its bite can be quite serious.• The male bullfrog will also aggressively defend his eggs if an animal or a human should approach. Very large, dull green in color. Can weight up to 4.4 pounds. Male is larger than female unlike many other frog species.
  14. 14. African Reed Frogs–• Endangered – habitat destruction.• These frogs are tree-hugging frogs, this helps protect them from predators on the ground.• Small suction cups located at the end of each toe are what enables these frogs to climb.• Brightly colored but not toxic.• Commonly confused with the poison arrow frog.• They survive the savanna by adjusting their There are over 150 species, they vary in water economy and metabolism. pattern and color. They grow to be about 1• Can change color dramatically depending on inch long the environmental conditions.
  15. 15. Boomslang –• Currently Not Endangered.• Well camouflaged and strikes without warning.• Delivers potent hemotoxic venom to its victim through large, deeply grooved folded fangs.• Prefers aerial positioning in tree top and shrub cover.• Lays eggs in the hollow of trees, Can grow up to 6 feet in length. Colors range protecting them from most to green brown and blue. Large eyes with egg predators. shaped head.
  16. 16. Gharial –• Endangered. – habitat destruction.• 106 to 110 very sharp teeth for catching fish.• Well-developed tail for swimming in water.• Rear feet have extensive webbing, also for swimming.• They leave the water only to bask and Short legs and long, thin snout with razor nest on sandbanks. sharp teeth.
  17. 17. Dung Beetle–• Currently Not Endanger.• Very important to the ecosystem.• Survive on feces.• Has good sense of smell used to find food.• Considered sacred to the ancient Egyptians.• They navigate by using the moon. Small, egg shaped, hard, black bodies. .
  18. 18. Termites –• Currently Not Endangered.• Colonies appear as grassy mounds that can reach 32-1/2 feet in diameter.• Mounds have a positive influence on local animal and plant activity.• During natural fires in the savanna, termites fly until it has passed.• All members of the colony have certain jobs to do and are specially design to do that job. Tiny, blind creatures less than 1/10th of an inch in size.
  19. 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, Kalahari Gemsbok National Park, and many others.
  20. 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 help protect these animals from endangerment and extinction. They are also raised and bred in captivity to give them a better chance of repopulation.
  21. 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. 22. •Biodiversity – The savanna ishome to many different animals •Migration –Tanzania is where oneand organisms.

It provides foodand other necessities to humans.
