Savannas usually get between 4 and 16 inches (100 to 400 mm) of rain in a year. These lands, however, are called savanna because of the type of plants that live there and how they get their rain. Savannas have a wet and dry season. During the wet season it can rain hard for long periods of time then not rain at all in the dry season. Savannas that have more rain often have many trees spaced out across their plains. These trees have deep roots or store water, like desert plants do, to live through the long, dry seasons without rain. Even drier savannas will have only grass, and that too only in a few clumps. The dry land is very bad for crops, but it is a wonderful place for all kinds of wild animals to gather and stay. That is why Kenya has a lot of parks where the animals are kept, and protected from all the hunters. People/tourists come from all over the world to go on photo safaris in Kenya's special wildlife parks. The people come to Kenya on safari to see animals such as the rhinoceros, giraffe, wildebeest, elephant, cheetah, antelope, and lion. These animals live on the savanna grasslands.
