Savannas are part of the Grassland biome, and are generally found in regions dominated by the “Wet-Dry Climate.” Tropical Savannas encompass almost one half of the entire continent of Africa as well as many parts of Australia, India, Mexico, and South America. The Tropical Savannas in Australia take up over one-third of the country, and provide natural resources that contribute much of the money that supports the national economy.The Climate is the most important factor in creating a savanna. Tropical Savannas are always found in hot weather with a mean temperature of among eighty-five to ninety degrees Fahrenheit, where the annual rainfall is from about twenty to fifty inches per year. Yet the rain does not fall at a constant rate all year. In fact, practically all the rainfall is condensed into six months of the year, known as the Wet Season. On the contrast, the following six months is a long period of drought, and yes, this time is called nothing but the Dry Season. Savannas, are often what surrounds the very wet Tropical Rain forest.The Abiotic factors, non-biological factors that are part of Savannas are temperature, climate, soil, and sunlight. All of these factors are crucial to the biome and how it the organisms in it succeed. Most Savanna soils are rather poor, but they have better quality of soil than that of the soil in the rain forest. But the savanna has less rainfall, and plants need water to survive. Biotic factors, or biological factors that influence and are a part of this biome are ALL organisms living in the biome. The vegetation of the Savannas consists of tall grasses such as star grass, and red oat grass both of which can grow reaching a height of three meters. Trees are present but not amply because since the water is so scarce, trees are unable to grow profusely and are subjected to grow in only the places wherever tree roots can reach underground water. A few notable species of trees in the sa...
