A grassland is an area where the vegetation is dominated by grasses . However, sedge and rush can also be found along with variable proportions of legumes, such as clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth.
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.
Annual grasslands are dominated by non-native annual grasses and forbs, with a few native perennial grass species present. These grasslands are subject to seasonal and yearly variations in species composition and productivity, which are largely controlled by the timing and amount of precipitation and temperature.
The Western Gulf coastal grasslands (Spanish: Pastizales costeros del Golfo Occidental) are a subtropical grassland ecoregion of the southern United States and northeastern Mexico. [ 2 ] [ 3 ] It is known in Louisiana as the "Cajun Prairie" , Texas as "Coastal Prairie," and as the Tamaulipan pastizal ( Spanish : Pastizal Tamaulipeco ) in Mexico.

A national grassland is an area of protected and managed federal lands in the United States authorized by Title III of the Bankhead–Jones Farm Tenant Act of 1937 and managed by the United States Forest Service.
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 treeline .
Desert (arid) grasslands 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. [2] Shrub-steppe is also a type of low-rainfall natural grassland.
Dry grasslands belong to different zones such as: the natural zonal or azonal/extrazonal vegetation and the semi-natural vegetation. Overall, there are 13 classes that fall under dry grasslands. Dry grassland areas are very important to biodiversity as they contain a wide range of plant and animal species. European dry grasslands have the ...
