Presentation Transcript

  1. Frédéric Salein Savanna • Markee D.

  2. Location • Savannas can be found over most of Africa, India, parts of South American, and the upper part of Australia. • Close to the equator staying between the tropics of cancer and capricorn regions (defenders). • Markee D

  3. Savanna Climate • The temperature ranges from 61˚F - 91˚F • Wet season tends to have a lower temperature while the dry season has higher temperatures. • Precipitation has an average of 30-50 inches (Buzzle).

  4. Savanna Features • Savannas are very dry • The rain fall occurs around six or 8 months out of the year. The rest of the year is just drought. • The soil of is constantly deprived of water. • Thin layer of humus on top of the soil. • The thin layer of humus allows vegetation (Defenders). Frédéric Salein

  5. Savanna Animals • Animals vary depending on the continents. • List of Animals include: Kangaroo, Crocodile, Lions, Leopards, Vultures, Cheetahs (Savanna Biome Facts). Gazelle, Impala, Zebra, Wildebeest, Elephant, Buffalo, Giraffe (Buzzle).

  6. Savanna Vegetation • Due to little fertility in the soil, grass is dominant in the biome. • Savannas in Africa can be either grasslands or shrub-lands (Buzzle). • Vegetation in the savannas include wild grass acacia trees, shrubs, tall grass, and baobab trees. • Grass and shrubs are clumped together. • Vegetation has adapted to the lack of water during the dry seasons (Biology).

  7. Savanna Biome Threats • Tourist taken on safaris increase the pollution in the air due to the vehicles. • Poaching in safaris pose a threat to elephants, lions, and other animals. • With few lions and too many herbivores the grass could be depleted (Savanna Biome). • The African Wild Dog, Black Rhinoceros, and Golden Cheeked Warbler, and Blue-throated Macaw are the animals endangered in this biome (Endangered Species).

  8. Abiotic Features • Fire is the main abiotic feature. Savannas over time could grow into tropical rainforest. • The soil supports just grass and shrubs and the occasional tree. • The water from the wet season is stored in plants so they last through the dry season (abiotic factors).

  9. Food web example • Markee D

  10. Interesting facts • The boab tree can store thousands of liter of water in its trunk and branches for the dry season. • During fires in the dry season the stems of plants aren't damaged but the leaves are. • Most forms of grass grow to at least one foot (flora). • Hyenas can weigh over 150 lbs. in adulthood. • Cheetahs can travel at speeds close to 70 mph (fauna). Philip Tellis
