Poaceae

Grasslands are areas where the vegetation is dominated by grasses (Poaceae); however, sedge (Cyperaceae) and rush (Juncaceae) families can also be found along with variable proportions of legumes, like clover, and other herbs.
Poaceae includes the cereal grasses, bamboos and the grasses of natural grassland and cultivated lawns and pasture.

Temperate grasslands, savannas, and shrublands

temperate grasslandtemperate grasslandstemperate grasslands, savannas and shrublands
For example, there are five terrestrial ecoregion classifications (subdivisions) of the temperate grasslands, savannas, and shrublands biome (ecosystem), which is one of eight terrestrial ecozones of the Earth's surface.
Temperate grasslands, savannahs, and shrublands are terrestrial biomes whose predominant vegetation consists of grass and/or shrubs.

Savanna

savannassavannahssavannah
Grassland vegetation can vary in height from very short, as in chalk grassland, to quite tall, as in the case of North American tallgrass prairie, South American grasslands and African savanna.
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.

Miocene

Late MioceneEarly MioceneMiddle Miocene
The appearance of mountains in the western United States during the Miocene and Pliocene epochs, a period of some 25 million years, created a continental climate favorable to the evolution of grasslands.
By the end of this epoch, the ancestors of humans had split away from the ancestors of the chimpanzees to follow their own evolutionary path . As in the Oligocene before it, grasslands continued to expand and forests to dwindle in extent.

Ecosystem services

ecosystem serviceenvironmental servicesecological services
The professional study of grasslands falls under the category of rangeland management, which focuses on ecosystem services associated with the grass-dominated arid and semi-arid rangelands of the world.
Such ecosystems include, for example, agroecosystems, forest ecosystems, grassland ecosystems and aquatic ecosystems.

Steppe

steppessemi-aridgrassland
Mid-latitude grasslands, including the prairie and Pacific grasslands of North America, the Pampas of Argentina, Brazil and Uruguay, calcareous downland, and the steppes of Europe.
In physical geography, a steppe is an ecoregion, in the montane grasslands and shrublands and temperate grasslands, savannas and shrublands biomes, characterized by grassland plains without trees apart from those near rivers and lakes.

Lion

Carnivores like lions, wolves and cheetahs and leopards are also found in temperate grasslands.
Typically, the lion inhabits grasslands and savannas but is absent in dense forests.

Great bustard

Otis tardaOtisbustard
Associated with the wild-plant diversity of the "unimproved" grasslands is usually a rich invertebrate fauna; there are also many species of birds that are grassland "specialists", such as the snipe and the great bustard.
These birds' habitat is grassland or steppe defined by open, flat or somewhat rolling landscapes.

Prairie dog

Other animals of this region include: deer, prairie dogs, mice, jack rabbits, skunks, coyotes, snakes, fox, owls, badgers, blackbirds (both Old and New World varieties), grasshoppers, meadowlarks, sparrows, quails, hawks and hyenas.
Prairie dogs (genus Cynomys) are herbivorous burrowing rodents native to the grasslands of North America.

Forb

herb
As flowering plants and trees, grasses grow in great concentrations in climates where annual rainfall ranges between 500 and 900 mm. The root systems of perennial grasses and forbs form complex mats that hold the soil in place.
The term is used in biology and in vegetation ecology, especially in relation to grasslands and understory.

Los Llanos (South America)

LlanosLos LlanosLlanos Orientales
Notable tropical and subtropical grasslands include the Llanos grasslands of South America.
This turns the woodlands and grassland into a temporary wetland, comparable to the Pantanal of central South America.

Meadowlark

Other animals of this region include: deer, prairie dogs, mice, jack rabbits, skunks, coyotes, snakes, fox, owls, badgers, blackbirds (both Old and New World varieties), grasshoppers, meadowlarks, sparrows, quails, hawks and hyenas.
Meadowlarks are New World grassland birds belonging to genera Sturnella and Leistes.

Rain

As flowering plants and trees, grasses grow in great concentrations in climates where annual rainfall ranges between 500 and 900 mm. The root systems of perennial grasses and forbs form complex mats that hold the soil in place.
Rain forests are characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1750 and 2000 mm. A tropical savanna is a grassland biome located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes, with rainfall between 750 and 1270 mm a year.

American bison

buffalobisonAmerican buffalo
Typical large mammals include the blue wildebeest, American bison, giant anteater and Przewalski's horse.
Their historical range, by 9000 BC, is described as the great bison belt, a tract of rich grassland that ran from Alaska to the Gulf of Mexico, east to the Atlantic Seaboard (nearly to the Atlantic tidewater in some areas) as far north as New York and south to Georgia and per some sources down to Florida, with sightings in North Carolina near Buffalo Ford on the Catawba River as late as 1750.

Montane grasslands and shrublands

montane grasslandmontane grassland and shrublandmontane shrubland
They are part of the montane grasslands and shrublands biome and also constitute tundra.
The biome includes high altitude grasslands and shrublands around the world.

Calcareous

calcareous soilcalcareous rockcalcareous rocks
Species richness is particularly high in grasslands of low soil fertility such as serpentine barrens and calcareous grasslands, where woody encroachment is prevented as low nutrient levels in the soil may inhibit the growth of forest and shrub species.
Calcareous grassland is a form of grassland characteristic of soils containing much calcium carbonate from underlying chalk or limestone rock.

Pliocene

Late PliocenePliocene epochEarly Pliocene
The appearance of mountains in the western United States during the Miocene and Pliocene epochs, a period of some 25 million years, created a continental climate favorable to the evolution of grasslands.
Deciduous forests proliferated, coniferous forests and tundra covered much of the north, and grasslands spread on all continents (except Antarctica).

Giant anteater

Typical large mammals include the blue wildebeest, American bison, giant anteater and Przewalski's horse.
The giant anteater can be found in multiple habitats, including grassland and rainforest.

Wolf

Carnivores like lions, wolves and cheetahs and leopards are also found in temperate grasslands.
The gray wolf is a habitat generalist, and can occur in deserts, grasslands, forests and arctic tundras.

Grazing

grazegrazersgrazed
Grassland vegetation often remains dominant in a particular area usually due to grazing, cutting, or natural or man-made fires, all discouraging colonization by and survival of tree and shrub seedlings.
Although grazing is typically associated with mammals feeding on grasslands, or more specifically livestock in a pasture, ecologists sometimes use the word in a broader sense, to include any organism that feeds on any other species without ending the life of the prey organism.

Tussock (grass)

Bunch grass
They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies.

Climate

A tropical savanna is a grassland biome located in semiarid to semi-humid climate regions of subtropical and tropical latitudes, with average temperatures remain at or above 18 C year round and rainfall between 750 mm and 1270 mm a year.

Flood-meadow

A flood-meadow (or floodmeadow) is an area of grassland or pasture beside a river, subject to seasonal flooding.

Wild horse

Temperate grasslands are the home to many large herbivores, such as bison, gazelles, zebras, rhinoceroses, and wild horses.
In general, wild horses are grazers that prefer to inhabit open areas, such as steppes and grasslands.

Rhinoceros

Temperate grasslands are the home to many large herbivores, such as bison, gazelles, zebras, rhinoceroses, and wild horses.
They are confined to the tall grasslands and forests in the foothills of the Himalayas.
