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. The habitat type differs from tropical grasslands in the annual temperature regime and ...
The Texas Blackland Prairies are a temperate grassland ecoregion located in Texas that runs roughly 300 miles (480 km) from the Red River in North Texas to San Antonio in the south. The prairie was named after its rich, dark soil. [3] Less than 1% of the original Blackland prairie vegetation remains, scattered across Texas in parcels. [4]
Woody plants, shrubs or trees may occur on some grasslands—forming savannas, scrubby grassland or semi-wooded grassland, such as the African savannas or the Iberian deheza. [ 17 ] As flowering plants and trees, grasses grow in great concentrations in climates where annual rainfall ranges between 500 and 900 mm (20 and 35 in). [ 18 ]
Biomes are often defined by their structure: at a general level, for example, tropical forests, temperate grasslands, and arctic tundra. [ 4 ] : 14 There can be any degree of subcategories among ecosystem types that comprise a biome, e.g., needle-leafed boreal forests or wet tropical forests.

The mean annual rainfall ranges from 280–600 mm (11–24 in) across the community with a rainfall peak in winter. The distribution of the Iron-grass Natural Temperate Grassland is located within various Aboriginal Nations, including lands of the Ngarrindjeri, Peramangk, Kaurna, Narrunga, Nukunu and Ngadjuri people.

In 1977, a 9,900 hectare (38 mi 2) parcel in La Pampa Province's southern dry grasslands were set aside as Lihué Calel National Park. [ 6 ] These accomplishments notwithstanding, the area's ecosystem has been under increasing pressure by grazing and irrigation activities, apart from population and economic growth themselves.
The grasslands are interspersed with areas of dry woodland as well as freshwater and saltwater wetlands and lagoons. The ombú , considered an emblem of the Humid Pampa (and not a proper tree but a herb), grows naturally north of the Río de la Plata and east of the Paraná, seldom south of the Río de la Plata and never south of the Salado .
