Savannah Biome By: Rebecca Bonta, JJ Hayes & Dylan Hodges Endangered Plant Species of the Savannah Impacts of Pollution
& Ecosystem Destruction Traffic Pollution Burning Grasslands Why is the Baobab Tree endangered? The Baobab Tree The Baobab Tree's Functions In the Savannah... Savannah's have warm temperatures year round but has two seasons that vary greatly. A savannah gets water during summer but the biome could not support that many trees or forests. A savannah is a rolling grassland with shrubs and trees. The winter is very long and dry and the summer is long and wet. The plants in a savannah biome are highly specialized to be able to survive in this environment of long periods of drought. To be able get water, these plants have long tap roots that can reach the deep water table. When people think of endangered species in a savannah biome, they normally think of endangered animal species. One of the endangered plant species in the savannah biome is the Baobab tree, which is a fruit bearing tree. The trees are only endangered in certain parts of Africa like Sudan, Darfu, Kordofan and the Blue Nile regions This tree is grows to more than 80 feet and they have thick trunks which can vary from 30 to 90 feet in diameter. These trees have so many useful functions for the animals in the savnnah biome and even humans. Their huge trunks are used to store water, the fruit they produce is consumed and the bark and foliage are used for many medicinal purposes. Their oil is also used for some beauty products. They are threatened by drought and overuse. Also lack of seed dispersal is a major problem for these trees. Normally the large animals would help these trees out by eating the Baobab Tree's fruits and disperse the seeds. Animals populations have decreased and because of this the Baobab Tree's have decreased too. Savannas in many regions of the world are set ablaze to clear land for farming, or by carelessness. Burning these grasslands releases toxins into the air and soil that compromises human and environmental health. Studies have shown that carbon dioxide levels can remain at a high risk level even after a year of the initial event. http://www.ehow.com/info_7843983_endangered-species-savanna-biome.html

Water table: the level below which the ground is saturated with water Crematogastor Ant Black Mamba Baobab Tree Elephant Grass Ever wondered what a savannah really was? How about what goes on in the savanna?
No? Like, don't care!YOU ARE NOW! Natural Plant Resources Works Cited The building of roadways leads to increased traffic and deposits of metals in the soil from automobile exhaust. The fact that ecosystems are being destroyed for roads and buildings means that plants are being cleared out, therefore animals die due to lack of food or shelter. Desertification The main cause for concern is desertification. Desertification has led to high poverty levels due to the lack of needed resources. Countries like South Africa are starting to look like the Sahara Desert which is roughly 6,000 km away. Fruit of the Baobab Tree Beauty Products The Trunk The fruit of the Baobab Tree How to help? Things are being done to help save the Baobab Tree. Conserving and limiting the amount of products people can make from the Baobab Tree is also a major step people are taking. Some people can even buy parts where the trees are in order to protect the trees. Here is one website making a difference:
http://www.mightybaobab.com/en/Baobab/news/mighty-baobab-conservation/ Gum Eucalyptus Tree The Gum Tree grows between 20 and 30 feet and has leaves that grow about 1 inch. They have creamy white flowers that grow in 1 inch clusters. The flowers grow in sunny, dry climates and cannot tolerate cold weather. The leafs are used by doctors to cure many infections and sicknesses. They also supply a good food source for koalas. The Jackalberry Tree Found all throughout Africa, and grown on top of termite mounds in heavy soil. The roots protect the tree from the termites, who do not eat the living wood. The Jackalberry tree can grow up to 80 feet tall and have a circumference of 15 feet, but most of the trees grow up to only 15 feet. The bark of the tree is so tough it is used as hard wood floors and the flowers are also used as medicine. Bermuda Grass The roots of the grass can grow up to 59 inches long while the blades of the grass only grow up to 4 inches. Bermuda Grass can grow in poor soil, but it prefers warm and moist climates. It is used to stop bleeding on wounds and good to protect soil from erosion. Summary In the savannah there so many resources that the plants and animals provide life with. Because of overuse and lack of seed dispersal , some species become endangered, like the Baobab Tree. The ecosystem overall can even become hurt by desertification, traffic pollution and burning grasslands. The savannah is also home to plants that provide resources to its ecosystem and humans like the Gum Eucalyptus Tree, Jackalberry Tree and Berumda Grass. They use their many functions to benefit their biome. Acacia Senegal Curcuma Desertification Gum Eucalyptus Tree Bermuda Grass Jackalberry Tree The Savannah biome is one of the more understated regions of the world. People in general don't realize what is happening here. Savannahs (or grasslands, whatever floats your yacht) are rapidly decreasing in size. We're not going to go all soft and plush on y'all and slam you with the horrible ASPCA commercials that make you want to bawl. But, we want you guys to know what types of things occur in the savannahs of Africa and the likes. True prairies and grasslands are becoming harder and harder to find. People are taming the wild lands, and the grasslands are becoming as extinct as the animals that are missing from them today. In Africa, national parks are being set up to preserve the grasslands. This will help the animals such as lions and elephants as well. Awareness The best and most effective way for change is taking action.
