Great Grasslands




Hi guys I just got to the huge savanna in Africa and it is hot but it is also very cold at night. The savanna has a hot and dry season. Savanna is grassland with scattered individual trees. Savannas of one sort or another cover almost half the surface of Africa and here is a picture of were I am. Because the savanna supports such a large number of species competing for living space, usually only one or a few kinds of grass are more successful than the others in a particular area. The are alot of fires in Savannas and they are most common in January the tip of the dry season. But funnyly enough it is vital for the biodiversity. In October, a series of violent thunderstorms, followed by a strong drying wind, signals the beginning of the dry season. Some of the larger grass can grow an inch or more in 24 hours. Different savannas support different grasses due to disparities in rainfall and soil conditions. The one I'm in is close to the coast and there are a lot of different life, plant and animal.




Next is my final
