Grassland in all its form supports a vast variety of mammals, reptiles, birds, and insects. Typical large mammals include the blue wildebeest, American bison, giant anteater, and Przewalski's horse. [21] The plants and animals that live in grasslands are connected through an unlimited web of interactions.
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.
Temperate grasslands, savannas, and shrublands are terrestrial biomes defined by the World Wide Fund for Nature. [1] The predominant vegetation in these biomes consists of grass and/or shrubs . The climate is temperate and ranges from semi-arid to semi-humid.
This is a list of terrestrial ecoregions as compiled by the World Wildlife Fund (WWF). The WWF identifies terrestrial , freshwater , and marine ecoregions . The terrestrial scheme divides the Earth's land surface into 8 biogeographic realms , containing 867 smaller ecoregions.

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.
Extent of montane grasslands and shrublands. Montane grasslands and shrublands are a biome defined by the World Wildlife Fund. [1] The biome includes high elevation grasslands and shrublands around the world. The term "montane" in the name of the biome refers to "high elevation", rather than the ecological term that denotes the region below the ...
The Terai–Duar savanna and grasslands is a narrow lowland ecoregion at the base of the Himalayas, about 25 km (16 mi) wide, and a continuation of the Indo-Gangetic Plain in India, Nepal and Bhutan. It is colloquially called Terai in the Ganges Basin east to Nepal, then Dooars in West Bengal , Bhutan and Assam east to the Brahmaputra River .
The WWF ecoregions are classified by biome type (tropical and subtropical moist broadleaf forests, temperate grasslands, savannas, and shrublands, tundra, etc.), and into one of eight terrestrial realms. Australia, together with New Zealand, New Guinea and neighboring island groups, is part of the Australasian realm. The IBRA bioregions ...
