Double click anywhere & add an idea The Savanna Climate Animals Plants Location Rainfall Temperature Typical winds Geology Soil Terrain Behavioral Adaptions Examples Physical Adaptations Symbiotic Relationships Examples Plant Adaptions The African West Elephant lives in the savanna in Africa. They can weigh up to 12,000 lbs. They grow to be about 9-11 ft. tall. They eat leaves, grass, roots, and bark off of trees. They have a complex system of communication, and are ranked very high on the intelligence scale. Zebras live on the savanna,a nd primarily consume grass. They live in herds, and their biggest preditors are hyenas, lions, and cheetahs. They belong to the horse family, and spend most of their day eating. The lion, or the, "King of Beasts," lives in many areas, but most commonly the grassy plains of the African savanna. The primarily consume hoofed animals such as antelopes, deer, and zebras. The Black Mamba is a very poisonous and deadly snake that lurks in the grassy plains of South Africa. The hyena lives in the African grasslands and is a scavenger. It usually eats the carcass of dead or dying animals. Known for the hystarical bark, the hyena is also identified with its black spotted ears Most of the animals that live on the savanna fallow the trend of hunting or grazing in packs or herds. Herbivores flourish with the abundance of grass roots and leaves in the savanna. Many animals, like the elephant, stick in close groups and develop positions or parts in their communities. Many of the animals are very fast on their feet, or can, and are able to, travel for long distances. This is in part to the fast preditors and low water supply at times in the savanna's different seasons The areas in orange are the locations of the savanna biome. The yellow fever tree(yellow acacia):This is the most common tree in the "wetlands" of the savanna and is called so because more mosquitoes are found around them Strangle fig: Known as the tree of life, the strangle fig lives mostly by rivers where water is abundent. It has twisted and contorted branches and produces figs on them. Baobab: Known as the upside down tree, can have a trunk up to 23 ft. in diameter. It is able to grow out of solid limestone itself Wild Date Palm Candelabra Euphorbia This tree lives near the equater and can be very poisonous. During winter, or the dry season, the flowers become yellow. It can grow up to 10-40 ft tall throughout their lifetime This tree grows up to 12 meters and is apart of the palm tree family. Many plants in pthe savanna have adapted to the bipolar seasons of this biome. They have a winter season where it is very dry for 5 months out of the year, and the summer season where it rains 7 months out of the year. Many trees have produced deep root systems that help tap water when water is scarce. The Baobab tree has adapted by growing their leaves in the wet season. Most Savannas recieve 30-40 inches of rainfall each year. Others recieve as little as 10-20, while on the other end of the spectrum, savannas can recieve up to 60 inches of rainfall. The African Savanna ranges from 68-78 degrees pn average and in the dry season it is cooler by just a few degrees.
The Austrailian Savanna is 75-80 degrees and is cooler as wel.l in the dry season, and goes down to around 70 degrees. The average winds of the savanna is as fallows on this map, and is about 5 meters per second generally in all areas of the Savanna. Is a grassy flatland covered in tall grass and shrubs. Most lie between rainforest and deserts. The soil in most Savannas are very very low in nutrients and very porous. They have a this layer of nutrients called humus. Savanna soil in some areas have large iron oxide deposits giving it a redish brownish colour. The terrain of the savanna is covered by shrubs and grass with multiple trees covering it too. The grass in some areas can grow up to 10 feet and would make it very hard to pass through these areas. The savanna doesn't have a very vibrant colour scheme and in the dry season the grass turns brown. There are natural sediments throughout the savanna but they are not defined by this. There are 21,000 Lions in Africa
There has been a large decrease in lions since the 1950s
There are 750,000 Zebras all together in the plains of Africa.
Due to hunting a poaching of the lions the population of them has gone down quite a bit meaing they have an abundance fo food. The Zebra population has gone down and some are endangered but over all supplies the lions with adequte food. Due to the large amount of human activity in the afican savanna with some of the coal burning and the brutal ecological imperialism humans have displayed for the land in Africa as of late could cause some major shifts in the system of ecology there.
