A tree savanna at Tarangire National Park in Tanzania in East Africa A grass savanna at Kruger National Park in South Africa. A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close.
The Candler Oak Tree is located in Savannah, Georgia, United States, and is estimated to have been growing since the 1700s, making it one of the oldest living landmarks in the area. It is 54 feet (16.5 meters) tall, has a circumference of 17 ft (5.2 m) and a 63-inch (160 cm) diameter.
Map of oak savanna distribution in North America. Although there are pockets of oak savanna almost anywhere in North America where oaks are present, there are three major oak savanna areas: 1) California, British Columbia, Washington and Oregon in the west; 2) Southwestern United States and northern Mexico; and 3) the prairie/forest border zone of the Midwestern United States.

In many savannas, tree densities are higher and are more regularly spaced than in forests. [4] The states of the Eurasian steppes and the North American Great Plains have been largely extirpated through conversion to agriculture. Nonetheless, as many as 300 different plant species may grow on less than three acres of North American tallgrass ...
African savannas occur between forest or woodland regions and grassland regions. Flora includes acacia and baobab trees, grass, and low shrubs. Acacia trees lose their leaves in the dry season to conserve moisture, while the baobab stores water in its trunk for the dry season. Many of these savannas are in Africa.
Vachellia tortilis, widely known as Acacia tortilis but now attributed to the genus Vachellia, [4] is the umbrella thorn acacia, also known as umbrella thorn and Israeli babool, [5] a medium to large canopied tree native to most of Africa, primarily to the savanna and Sahel of Africa (especially the Somali peninsula and Sudan), but also occurring in the Middle East.
For Phillip Tobias, the 1994 find of Little Foot, the collection of Australopithecus africanus foot bones demonstrating features consistent with tree-climbing as well as an upright gait, contributed to calling the savannah hypothesis obsolete, stating Open the window and throw out the savannah hypothesis; it's dead and we need a new paradigm.
