They are covered with tall grasses. They may have scattered bushes and trees, but not enough to keep grasses from growing. One common example of a savanna is the tropical [[grassland]], in Africa. They have seasonal rains and dry periods. All savanna plants and trees can survive periods of [[drought]].<ref name=bluePlanet>{{cite web|title=World Savanna Biomes|url=http://www.blueplanetbiomes.org/savanna.htm|publisher=BluePlanetBiomes|accessdate=27 April 2013}}</ref> During the dry season the animals migrate north to countries on the East coast. Until the 20th century the elephant herds moving up the East coast were in the tens of thousands. They are far fewer today. Some savannas get enough rain to support a [[forest]], but the forest never happens because [[grazing]] keeps the trees from growing. Instead, there is lots of [[grass]]es and other plants that can regrow from the roots.<ref>{{cite web|title=Tropical savannas|url=https://php.radford.edu/~swoodwar/biomes/?page_id=105|publisher=Radford University|accessdate=27 April 2013|archive-date=19 December 2013|archive-url=https://web.archive.org/web/20131219124459/https://php.radford.edu/~swoodwar/biomes/?page_id=105|url-status=dead}}</ref> ==Africa== The savannas of [[Africa]] are the best known savannas. Some large [[herbivore]]s found in the savanna are [[antelope]]s, [[impala]]s, [[gazelle]]s, [[Bison|buffalo]]s, [[wildebeest]]s, [[zebra]]s, [[Rhinoceros|rhino]]s, [[giraffe]]s, [[elephant]]s, and [[warthog]]s. Many large [[carnivore]]s eat them, including cats ([[lion]]s, [[leopard]]s, [[cheetah]]s, [[serval]]s), dogs ([[jackal]]<nowiki/>s, wild dogs), and hyenas. The vegetation in Eastern Africa is also rich with grass and some scattered trees, mostly [[acacia]] trees. The dry season is the w
