The Savanna Biome Beau Duchesne & Kayla Garner 4th block The Savanna Biome Savannas have warm temperature year round. There are actually two very different seasons in a savanna; a very long dry season (winter), and a very wet season (summer). In the dry season only an average of about four inches of rain falls. Between December and February no rain will fall at all. Oddly enough, it is actually a little cooler during this dry season. But don't expect sweater weather; it is still around 70° F. In the summer there is lots of rain. In Africa, the monsoon rains begin in May. An average of 15 to 25 inches of rain falls during this time. It gets hot and very humid during the rainy season. African savannas have large herds of grazing and browsing hoofed animals. Each animal has a specialized eating habit that reduces competition for food. There are several different types of savannas around the world. The savannas that most know about are the East African savannas covered with acacia trees. The Serengeti Plains of Tanzania are some of the most well known. Here animals like lions, zebras, elephants, and giraffes and many types of ungulates (animals with hooves) graze and hunt. Many large grass-eating mammals can survive here because they can move around and eat the plentiful grasses. There are also lots of carnivores who eat them in turn. South America also has savannas, but there are very few species that exist only on this savanna. In Brazil, Colombia, and Venezuela, savannas occupy some 2.5 million square kilometers, an area about one-quarter the size of Canada. Animals from the neighboring biomes kind of spill into this savanna. Brazil's Cerrado is an open woodland of short twisted trees. The diversity of animals is very great here, with several plants and animals that don't exist anywhere else on earth. There is also a savanna in northern Australia. Eucalyptus trees take the place of acacias in the Australian savanna. There are many species of kangaroos in...
