Major types of trees adapted to this biome are pine, palm and acacia amongst others. The density of oligochaete worms, spiders and insects in the Guinea Savanna of tall grasses of the western Africa is 50,000 to 60,000 per 300 square metres of area during dry season but the density of these organisms increases to 1,00,000 during wet season because of regeneration of dense cover of green grasses. African Savanna Climate The Savanna biome has a wet/dry climate. There are savanna's located in Africa, South America, India, and Australia. The roots of the Savanna trees have also developed according to the environmental conditions as they are very large which can penetrate into the soil and ground up to the depths from 5m to 20m so they can obtain water from groundwater even during dry season when the groundwater table falls considerably. The savanna is usually is warm with tempertures ranging from 68 degrees to 86 degrees, so probably not as hot as it appears. Even a forested area can become a savanna if humans clear out all the trees and convert the land to grassland for their livestock. The dry season comes during winter. The dry season which occurs in the months of October-January only receives about 4 inches of rain. They are mostly located near the equator. These winds, combined with the dry weather, can often promote the quick spread of fires, which cause animals to flee the area. In the wet season, temperatures are usually warm. Not enough rain falls on a savanna to support forests. Savannas can be found in the American midwest, such as this oak savanna in Wisconsin. The rapid rate of expansion in the agricultural lands under the new scheme of green revolution has further been responsible for the shrinkage of natural Savanna grasslands. The climate is usually warm and temperatures range from 68° to 86°F (20 to 30°C). Some of the Savanna trees are fire resistant (pyrophytic) as they have thick bark and thick bud-scales. Most birds and animals are lucky because they have legs or wings and can flee the fires. But this phenomenon may not be unique to humans. Report a Violation 10. Man and Savanna Biome. Rainfall picks up in May, starting the wet season, and ends in … There are clear-cut evidences to demonstrate that the savanna regions of India have certainly originated and developed because of deforestation of the original forests by man because Indian savanna areas are found within and around deciduous forest covers. These are known as derived savanna. Savannas are generally found between the desert biome and the rainforest biome. Image by CT Cooper. The impact of man in the Savanna biome right from the evolution of human races in the various parts of the present-day Savannas to the present-day technologically advanced society has been so immense that the very nature and the characteristics of Savanna grasslands are the outcome of the continued man’s interferences with the original natural environmental conditions particularly natural vegetation and related micro-climates. However, in order for the savannas to survive, they must have the long dry periods. To survive the dry season, plants have grown long roots to suck all the moisture out of the ground.

If you are interested in helping with the website we have a Volunteers page to get the process started. Thus, the Savanna biome is characterized by the development of grazing succession which enables the animals of various species and sizes to live in the same habitat without having much competition among themselves for food.
