The Savanna biome, also known as the Savannah biome, is a relatively flat and dry biome similar to the plains, except for the plateaus and numerous trees found in the Savanna.
Version 1.7 of Minecraft will mark the second time the Savanna has been in the game, the first being from Alpha 1.2.0 - Beta 1.8. (see below)
The Savanna is a relatively flat and dry biome with yellow-tinted grass and several Acacia Trees. Horses can be found in this biome, as well as NPC Villages. These savannas are based on the savanna plateaus of southern Africa.
The Savanna biome was officially released alongside three variations, which follow:
 Savanna Plateau
A plateau like in the mesa biome, is raised up to about 30 blocks above sea level. These make up much less of the area than in the mesa biome, but are easily seen as sudden walls of hill. Like the mesa plateau, they are very flat on top.
 Savanna M
A variation of the Savanna. These are quite rare, and consist of stone and grassless dirt, and are more mountainous than their regular counterpart. These mountains can almost reach the cloud limit, and sometimes go slightly above, even without using the AMPLIFIED world type.
 Savanna Plateau M
An extremely mountainous variation caused by the plateau and the M variation combining, with very steep hills very much around, with Acacia Trees atop them. The generation of this biome can cause several strange 'structures' to be created. Their peak has a huge range of altitudes. They can go above Y: 200 sometimes, whilst others don't reach the clouds. These have a huge amount of variation and are the closest to AMPLIFIED terrain on default. Like the M variation, these have a lot of exposed stone and grassless dirt. Some consider these an eyesore, whilst others really enjoy the variation this biome offers.
 Pre-Beta 1.8
Between Alpha 1.2.0 and Beta 1.8, one of the eleven biomes was the "Savanna". This version of the Savanna was different from the forthcoming version; the former having almost no trees, and slightly darker grass. However, the mostly flat terrain is shared between the two.
|1.2.0||The biome introduced alongside 10 others.|
|1.8||The biome, and the other ten, were removed to make way for new ones.|
|1.7.2||13w36a||The biome re-introduced, with various changes, alongside various others.|
|1.7.2||13w43a||Jungle wood in the Acacia trees is replaced by Acacia wood.|
