The tropical and subtropical grasslands, savannas, and shrublands are characterized by rainfall levels between 90–150 centimetres (35–59 in) per year. [1] Rainfall can be highly seasonal, with the entire year's rainfall sometimes occurring within a couple of weeks. African savannas occur between forest or woodland regions and grassland regions.
Also called desert grasslands, they are composed of sparse grassland ecoregions located in the deserts and xeric shrublands biome. Temperature extremes and low amounts of rainfall characterise these kinds of grasslands. Therefore, plants and animals are well adapted to minimize water loss. [62]
Tropical deserts are located in regions between 15 and 30 degrees latitude. The environment is very extreme, and they have the highest average monthly temperature on Earth. Rainfall is sporadic; precipitation may not be observed at all in a few years. In addition to these extreme environmental and climate conditions, most tropical deserts are ...
The savannas of northern Australia, sub-Saharan Africa, Asia and South America are examples of tropical grasslands. The climate is warm with contrasting rainy and dry seasons.
Rangelands in South America exclude hyperarid deserts. Examples of the South American rangelands include the Patagonian Steppe, the Monte, the Pampas, the "Llanos" or "Cerrado," the "Chaco" and the "Caatinga." The change in the intensity and location of tropical thunderstorms and other weather patterns is the driving force in the climates of ...
In physical geography, a steppe (/ s t ɛ p /) is an ecoregion characterized by grassland plains without closed forests except near rivers and lakes. [1] Steppe biomes may include: the montane grasslands and shrublands biome; the tropical and subtropical grasslands, savannas, and shrublands biome; the temperate grasslands, savannas, and ...

The Humid Chaco (Spanish: Chaco Húmedo or Chaco Oriental) is tropical grasslands, savannas, and shrublands ecoregion in South America. It lies in the basin of the Paraná River, covering portions of central Paraguay and northern Argentina, and with a small portion of southwestern Brazil and northwestern Uruguay. The natural vegetation is a ...
