Savanna

A savanna is a dry biome with scattered acacia trees. It typically generates bordering a desert, forest or plains biome and has three variations total.

Description
Savannas are mostly flat biomes, with vast amounts of tall grass all over the terrain. Acacia and small oak trees are the two types of trees that grow here; this is the only place where acacia trees naturally generate.

Villages that generate in savannas are made mainly of terracotta, acacia logs, and planks; the bright-orange acacia planks make savanna villages easy to spot from a distance. Pillager outpost s may generate as well.

Horses, donkeys and llamas spawn in savannas. This does make it the only biome where horses and llamas can spawn together. As the savanna has an arid climate, it never rains here and thus lightning can never naturally strike; however, overcast skies (and daytime hostile mobs spawning in the case of thunderstorms) still apply. Grass and leaves in the savanna take on an olive-green color, giving an illusion of dryness.

Survival in the normal savanna, along with its plateau variant, is generally easy. The acacia and oak trees provide a decent source of wood, tamed horses can allow for fast travel and outrunning hostile mobs, tamed llamas can serve as useful pack animals and villages can serve as a refuge and a way to trade items. However, the vast amounts of tall grass can prove to be a nuisance when building a shelter; additionally, it may serve as an obstacle when fighting hostile mobs, as the player might end up hitting the grass rather than the mob. Survival in the windswept savanna variant, however, is dangerous due to the extremes of the generated mountains.

Savanna Plateau
The savanna plateau is identical to the regular savanna, though villages and pillager outpost do not generate here. This biome is found when a savanna generates on top of a plateau or beneath a stony mountain. Horses still spawn on the plateaus and this is the only savanna sub-biome where llamas spawn.

$$, savanna plateaus use the same mob spawning chances as savannas for ambient and hostile categories. As for the others:

Windswept Savanna
The rare windswept savanna variant generates in areas with high erosion and very low factor, which means that the terrain is arguably the most chaotic in the game, a contrast from the otherwise flat savanna. The terrain is covered with a mixture of grass patches and stone patches, with coarse dirt in between. It is full of extremely steep mountains, enormous overhangs, floating islands and huge waterfalls and lavafalls, with higher and rougher terrain than the windswept hills biome, and can often go past the layer 200. Llamas cannot spawn and villages and pillager outposts cannot generate in this biome, though horses and other passive mobs remain prevalent on the cliffs, and trees can still spawn naturally. Large and deep lakes often form on the bases of the mountains. The steep generated mountains make this variant almost unsuitable for shelter and even just exploring quite hazardous, due to the sharp cliffs often risking fatal fall damage if not above water. Additionally, the giant overhangs often reduce skylight on the terrain below them, not only enough to spawn hostile mobs in daylight, but to produce complete darkness similar to caves, further adding to the difficulty of this biome.

Windswept savanna biomes can often generate standalone bordering other biomes that aren't just the default savanna, with these biomes usually being temperate or warm. Windswept savannas can't generate in regions with cold or snowy biomes which means that these biomes can be found in extreme terrain.

Windswept savannas use the same mob spawning chances as savannas.
