A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on Earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area.
A savanna or savannah is a mixed woodland-grassland ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. There exists four savanna forms; savanna woodland where trees and shrubs form a light canopy, tree savanna with scattered trees and shrubs, shrub savanna with distributed shrubs, and grass savanna where trees and shrubs are mostly nonexistent.
Pasture is land used for grazing.
Acacia aneura, commonly known as mulga or true mulga, is a shrub or small tree native to arid outback areas of Australia. It is the dominant tree in the habitat to which it gives its name (mulga) that occurs across much of inland Australia. Specific regions have been designated the Western Australian mulga shrublands in Western Australia and Mulga Lands in Queensland.
Rangelands are grasslands, shrublands, woodlands, wetlands, and deserts that are grazed by domestic livestock or wild animals. Types of rangelands include tallgrass and shortgrass prairies, desert grasslands and shrublands, woodlands, savannas, chaparrals, steppes, and tundras. Rangelands do not include forests lacking grazable understory vegetation, barren desert, farmland, or land covered by solid rock, concrete and/or glaciers.
The spectacled hare-wallaby is a species of macropod found in Australia and New Guinea. In Australia, a small sub-population is found on Barrow Island, while the mainland type is widespread, though in decline, across northern regions of the country.
The Lake Mackay hare-wallaby, also known as the central hare-wallaby or kuluwarri, is an extinct species of macropod formerly found in central Australia. Very little is known about it.
The Ord Victoria Plain, an interim Australian bioregion, is located in the Northern Territory and Western Australia, comprising 12,540,703 hectares.
Atriplex vesicaria, commonly known as bladder saltbush, is a species of flowering plant of the family Amaranthaceae and is endemic to arid and semi-arid inland regions of Australia. It is an upright or sprawling shrub with scaly leaves and separate male and female plants, the fruit often with a bladder-like appendage.
Panicum decompositum, known by the common names native millet, native panic, Australian millet, papa grass, and umbrella grass, is a species of perennial grass native to the inland of Australia. It occurs in every mainland state. The seeds can be cultivated to produce flour typically used in Aboriginal bushfood. The species is also considered to have relatively high palatability by livestock, making it suitable for grazing pastures.
Chrysopogon is a genus of tropical and subtropical plants in the grass family. They are widespread across Eurasia, Africa, Australia, southeastern North America, and various islands.
Microlaena stipoides, synonym Ehrharta stipoides, is a species of grass. It occurs naturally in all states of Australia as well as in New Zealand, Papua New Guinea, Indonesia and the Philippines. It has also been introduced into Hawaii and Reunion Island and has been reported as invasive in both. Common names used include weeping grass, weeping rice grass and weeping meadow grass.
The Carpentaria tropical savanna is a tropical and subtropical grasslands, savannas, and shrublands ecoregion in northern Australia.
The Victoria Plains tropical savanna is a tropical and subtropical grasslands, savannas, and shrublands ecoregion in northwestern Australia.
Andropogon gayanus, commonly known as gamba grass, Rhodesian blue grass, tambuki grass, and other names, is a species of grass native to most of the tropical and subtropical savannas of Africa.
Bothriochloa pertusa is a species of grass. It is widely used as a fodder and a graze for livestock.
Dichanthium annulatum is a species of grass in the family Poaceae. It is commonly used as a forage for livestock.

Woody plant encroachment is a natural phenomenon characterised by the increase in density of woody plants, bushes and shrubs, at the expense of the herbaceous layer, grasses and forbs. It predominantly occurs in grasslands, savannas and woodlands and can cause regime shifts from open grasslands and savannas to closed woodlands. The term bush encroachment refers to the expansion of native plants and not the spread of alien invasive species. It is thus defined by plant density, not species. Woody encroachment is often considered interpreted as a symptom of land degradation. The phenomenon is observed across different ecosystems and with different characteristics and intensities globally.
Eragrostis setifolia, commonly known as neverfail grass, is a species of perennial grass in the family Poaceae native to Australia, where it is widespread and common throughout the range lands and is commonly utilized as a pasture grass. According to IUCN classification it is listed as a least concern species throughout most of its range with the exception of Victoria where it is classified as vulnerable. It is capable of C4 photosynthesis.
