Savanna Biome
By: Rasleen, Jasmine & Donneal

2. Introduction
Savannah is another name for tropical grasslands. They are usually flat and covered in grass, but also with other plants, low shrubs and a few trees. They receive less rainfall then the rainforest but more than the desert. They have a lot of different grasses. Most of them are located in between the tropical rain forests and the desert.
The largest Savannas' are found in :
Africa- one third of it is covered with Savannas'
South America- 300, ,000sq. Is covered with Savannas’
Australia- 70% of the continent.
India- covers 17,40000km

4. Climate &Weather

5. Habitat & Climate:
HabitatA Savanna has a wet/dry climate. Savanna is a rolling grassland scattered with shrubs and isolated trees, which can be found between a tropical rainforest and desert biome. Savannas are also known as tropical grasslands. They are found in a wide band on either side of the equator on the edges of tropical rainforests. There are several different types of savannas around the world. The savannas we are most familiar with are the African Savannas covered with trees. The Serengeti Plains of Tanzania are some of the most well known. South America also has savannas, but there are very few species that exist only on this Savanna. In Brazil, Colombia, and Venezuela, savannas take up 2.5 million square kilometres. With no vegetation, the savannah turns into a desert. Huge areas of Savanna are lost to the Sahara desert every year because of overgrazing and farming.
ClimateSavannas have warm temperature year round. There are actually two very different seasons in a Savanna, a very long dry season (winter), and a very wet season (summer). In the winter only about 4 inches of rain falls. Between December and February no rain falls at all. Savannas get all their rain in the summer months. During the dry season of a Savanna, most of the plants shrivel up and die. Some rivers and streams dry up. Most of the animals migrate to find food. It is usually cooler during the dry season by a few degrees. The Savanna climate has a temperature range of 20° - 30° C. In the winter, it is usually about 20° - 25° C. In the summer the temperature ranges from 25° - 30° C. In a Savanna the temperature does not change a lot. When it does, its very gradual and not drastic. There is a total precipitation of 10 to 30 inches (100 to 150 cm) of rain.

6. Questions:
What if you were to change the particular habitat/weather of a biome? -If you were to change the weather then the plants could not develop and grow. They are adjusted to grow in hot temperatures and if the weather changes then they cannot grow and will eventually die.
- If you change the habitat of a biome then the animals that live with it can’t stay there no longer, because they have already been adapted to it. They wouldn’t have anywhere else to go because they already adapted in the 2 Savanna season’s.
What if the rainfall increases or decreases? - If the rainfall increases it will be too much for the Savanna because its not suppose to rain at December, January & February. The plants will not grow, but will get weaker instead & without too less rainfall then the plants will not be able to grow so they die either way.

7. Further Questions:
What are the two seasons names in the Savanna? - In the Savanna the two seasons are: dry season- summer & wet season- winter
What is another name for the Savanna? - Another name for the Savanna is Grasslands, because they have a lot of different grasses because it isn’t a rainforest were it always rains or a desert were there no rain so there is some plant life.

8. Animals

9. Background information:
Savannas' lack the trees and heavy bush to hide many creatures. Because of the open landscape and the widely spaced trees, grasslands are home to large herds of grazing mammals such as the zebra and bison. Many animals are active only during the rainy season. Savannas' are full of life, with many animals that rely on the resources of Savannas’ to provide them with food and shelter. The animals that live in grasslands have to adapt to dry, windy, and wet conditions. There are grazing animals, burrowing animals, and their predators. Some of the animals are very small such as mice, prairie dogs, snakes, lizards and insects. These animals can hide easily in the grasses from predators. Elephants, lions, zebra, giraffes, cheetah and kangaroos have to protect themselves from the predators another way.

10. ANIMALS:
Peacocksmostly live in the Savannah because they do better in warm climates then colder ones. They are usually in groups because they cannot hunt alone. Also they eat grains and fruits but these supplies aren’t available all year around. When this food is not available to them they eat small amphibians and reptiles.
Brown Hyena’s also live in the Savannah. Brown Hyena’s can live in severe conditions, which other animals cannot. They are scavengers, but they kill if there is no food source available to them. Their sharp teeth go onto the bone of the animal to get the nutritious value out of it. Brown Hyena’s usually stay in groups.
Big Horn Sheep the name basically says it all. These sheep have big horns that curve in & they hit predators with them. They live in the Savannah because it is easier for them to walk on the sand other then rocks, snow, or muddy areas.
Rhinocerosesthey use their upper lip to eat small and low plants. A rhino can run 30 miles per hour and when predators are close they have great hearing skills so they can just attack with their huge tusk.

11. Questions:
What would happen if you were to move an animal in another biome?
The animal couldn’t survive as well because the weather and habitat change. All their surroundings would change, and they won’t adapt as well as their old habitat. They wouldn’t have the same resources and wouldn’t have anything for survival. So the animals would eventually die.
What if a developer wants to build something, what if an animal becomes extinct?
- If an animal becomes extinct then it ruins the whole food chain and the food web. Its better for the Savanna without any construction.

12. Further questions:
Why do small animals hide in the grass?
- Small animals hide in the grass because they are able to and because they have to hide from their predators. So the grass is the safest place to blend in and hide.
What weathers do animals in the Savannah have to adapt to in order to survive?
- Animals in the Savannah have to adapt to dry, windy, and wet conditions.

13. Plant Life

14. Plants:
A Savannah is a rolling grassland scattered with shrubs and isolated trees. These plants can be found between a tropical rain forest and a desert biome. The east African savannah is covered with acacia trees. Acacia Trees are a leaf shape Fern-like stalk. Their normal height is 40 feet. The best habitat for these trees is a warm region. There are over 800 species of acacia trees in Savannah's all around the world. The acacia plant can grow up to 20 meters tall. The Acacia can live through long periods of no rain. They tend to grow in sandy places where there is only inches of Rain a year.

15. Questions:
What if a plant were destroyed? If a plant were destroyed then some animal’s wouldn’t have any plants to rely on and become extinct
What if rainfall greatly increases or decreases?
You cannot have to much rainfall or too less you have to have just the same amount so the plant doesn’t start breaking apart, or become weaker.

16. Further questions: What conditions do Acacia trees live in?
Acacia trees live in warm to really hot conditions.
What is the East side of the African Savanna covered with?
All of the east side of the Savanna is covered with Acacia trees.

17. Human Influences

18. Background Information:
Some human influences that happen in the Savanna are:
Fires
Over farming
Agriculture
Deforestation
Poaching

19. HUMAN INFLUENCES:
Fires- People set some parts of the Savanna on fire because they don’t want it to turn into a successful forest.
Over farming- they take to much of the land, and the soil and nutrients.
Agriculture- People replace natural fields, with grain crops. They replaced the native ecosystem and then the wildlife and plant life was no longer there.
Deforestation- they are clearing trees, so its ruining animals habitats.
Poaching- means that they are illegally catching animals and taking them away from their biome.

20. Further Questions:
What does poaching mean? -Poaching is when people take animals out of their habitats/biomes illegally.
Why is over farming bad?
-Over farming is bad because they take to much of the land up, and take away the soil and nutrients.

21. Landscape

22. Savannah Landscape:
Savanna’s are grasslands scattered with grasses and leafy plants. There are two types of grasslands in a savanna the tropical and the temperate . The tropical grassland no seasonal changes but does change seasons from wet to dry. The temperate grassland has hot summers and cold winters. A grassland is basically a field with endless trees and plants scattered all around.

23. Temperate AND TROPICAL LANDSCAPES:
Temperature: warm to hot in the summer and cold to freezing in the winter
Soil: fertile with rich nutrients and minerals
Plants: grass, trees, shrubs etc
Animals: large, grazing mammals, birds etc
Tropical 
Temperature: changes from wet to dry through out the seasons
Plants: acacia brushes, thorns etc
Animals: vultures, birds, rodents etc

24. Questions:
What if you were to change the landscape of a particular biome?
- If you changed the landscape then animals and plants couldn’t survive, because they are already adapted to the other landscape.

25. Futher QUESTIONS: What are some problems affecting the Savanna today?
Wild fires are one of the problems affecting Savannas’  today because they spread fast and burn down the plants and trees. They  ruin the whole land and kill animals and there habitats. Another problem is increase of population this is when cities or towns have to expand there borders and destroy habitats and plants and animals.
What are three ecosystems in a tropical Savanna?
Three ecosystems in a tropical Savanna are the  grasslands, riparian and kopje.
