The Pampas are fertile South American low grasslands that cover more than 1,200,000 square kilometres (460,000 sq mi) and include the Argentine provinces of Buenos Aires, La Pampa, Santa Fe, Entre Ríos, and Córdoba; all of Uruguay; and Brazil's southernmost state, Rio Grande do Sul. The vast plains are a natural region, interrupted only by the low Ventana and Tandil hills, near Bahía Blanca and Tandil (Argentina), with a height of 1,300 m (4,265 ft) and 500 m (1,640 ft), respectively.
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 Llanos is a vast tropical grassland plain situated to the east of the Andes in Colombia and Venezuela, in northwestern South America. It is an ecoregion of the tropical and subtropical grasslands, savannas, and shrublands biome.
The Humid Chaco is tropical grasslands, savannas, and shrublands ecoregion in South America. It lies in the basin of the Paraná River, covering portions of central Paraguay and northern Argentina, and with a small portion of southwestern Brazil and northwestern Uruguay. The natural vegetation is a mosaic of grasslands, palm savanna, and forest.
The Semi-arid Pampas, also known as the Dry Pampas, is a temperate grassland ecoregion of central Argentina.
The Upper Gangetic Plains moist deciduous forests is a tropical and subtropical moist broadleaf forests ecoregion of northern India.
The Humid Pampas is an extensive ecoregion of flat, fertile grassland of loessic origin in Argentina. It has a precipitation average of 900 mm per year, in contrast with the Dry Pampas to the west, which average less than 700 mm.
The Northern Congolian forest–savanna mosaic is a forest and savanna ecoregion of central Africa. It extends east and west across central Africa, covering parts of Cameroon, Central African Republic, Democratic Republic of the Congo, South Sudan, and Uganda. It is part of the belt of transitional forest-savanna mosaic that lie between Africa's moist equatorial Guineo-Congolian forests and the tropical dry forests, savannas, and grasslands to the north and south.
The puna grassland ecoregion, of the montane grasslands and shrublands biome, is found in the central Andes Mountains of South America. It is considered one of the eight Natural Regions in Peru, but extends south, across Chile, Bolivia, and western northwest Argentina. The term puna encompasses diverse ecosystems of the high Central Andes above 3200–3400 m.
The Araucaria moist forests, officially classified as mixed ombrophilous forest in Brazil, are a montane subtropical moist forest ecoregion. The forest ecosystem is located in southern Brazil and northeastern Argentina. The ecoregion is a southern portion of the Atlantic Forest. The ecoregion also includes select areas of open field called "campos de cima da serra" or "coxilhas".
The Alto Paraná Atlantic forests, also known as the Paraná-Paraíba interior forests, is an ecoregion of the tropical moist forests biome, and the South American Atlantic Forest biome. It is located in southern Brazil, northeastern Argentina, and eastern Paraguay.
The Southern Cone Mesopotamian savanna, also known as the Argentine Mesopotamian grasslands, is a flooded grassland ecoregion of Argentina and southern Paraguay.
Serras de Sudeste is a dissected plateau, also named Planalto Dissecado de Sudeste or Escudo Sul-Rio-Grandense, located in the southeastern portion of Rio Grande do Sul state in southernmost Brazil, near Uruguay.
The Central Mexican matorral is an ecoregion of the deserts and xeric shrublands biome of central Mexico. It is the southernmost ecoregion of the Nearctic realm.
The Environment of Argentina is characterised by high biodiversity.
The Carpentaria tropical savanna is a tropical and subtropical grasslands, savannas, and shrublands ecoregion in northern Australia.
The Southeast Australia temperate savanna ecoregion is a large area of grassland dotted with eucalyptus trees running north–south across central New South Wales, Australia.
The Paraná flooded savanna (NT0908) is an ecoregion that borders the southern Paraná River in Argentina. It has largely been converted to agriculture or occupied by urban development, but scattered patches of the original habitat remain along the river.
The Espinal (NT0801) is an ecoregion of dry, thorny forest, savanna and steppe in Argentina. It has been extensively modified by large scale cattle ranching, but remnants of the original flora remain. It is threatened by the advance of the irrigation-based agricultural frontier.
The Western Congolian forest–savanna mosaic is an ecoregion of Angola, Democratic Republic of the Congo, Republic of the Congo, and Gabon.
