WELCOME

Welcome to the Savanna web page, created by Salvatore Jenkins, Jack Barret, and Jinsop Pro. This page was created for a science project, the purpose of this was for us to learn about different Ecosystems. There were four groups and each go a form of Ecosystem to study, when our group got all of our information was found we had to work on our project. We choose making a web page , because computers is SJ specialty and it was the best choice there.

 

Info:

    Savanna, also Savannah, tropical grassland with a scattering of shrubs, small and large trees. Savannas may result from soil conditions, from periodic fires caused by lightning or set by humans, or from climatic influences.Climatically determined savannas, as found mostly in  Africa, develop in regions with marked wet and dry seasons, where rainfall ranges between 4 and 16 in a year. These savannas vary from open-canopied(An ornamental rooflike structure), forests with a grassy understory to true savannas in which grasses are dominant. When the rainfall is 4 to 8 in, generally only grasses can survive the dry season. When rainfall reaches 12 in, the soil holds enough water to sustain shrubs through the dry season as well. When rainfall exceeds 300 mm, enough water is left to support solitary trees; and when rainfall exceeds 400 mm, enough moisture remains during the dry season to allow trees to grow more densely and to form a canopy, shading out the grasses.

             Savanna vegetation is maintained by periodic fires. Consuming dry grass at the end of the rainy season, the fires burn back the forest vegetation, check the invasion of trees and shrubs, and stimulate new grass growth. These savannas are also influenced by large grazing mammals such as wildebeest and zebra. When abundant, the animals can so reduce the vegetation that the grassy cover cannot carry a fire. Woody vegetation then increases, changing savanna to woodland. Such woody growth can be reduced, in turn, by large predators such as elephants.
