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 ]
Grasslands — also known as savannas, prairies, steppes and pampas — are ecosystems found in parts of the world that do not get sufficient consistent rainfall to support forest growth, but get ...
Savanna and grassland: The California Central Valley grasslands are the largest Mediterranean grassland eco-region, although these grasslands have mostly been converted to agriculture. The remaining woodlands feature mainly oak, walnut and pine. The cork oak savanna in Portugal, known as montado, is a good example of a mediterranean savanna.
A tree savanna at Tarangire National Park in Tanzania in East Africa A grass savanna at Kruger National Park in South Africa. A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close.
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.
Grasslands first appeared millions of years ago due to radical changes in climate and have been key to human survival for at least 10,000 years, by offering pasture for livestock and fields for crops.
The biome, called "Montane grasslands and shrublands", often evolved as virtual islands, separated from other montane regions by warmer, lower elevation regions, and are frequently home to many distinctive and endemic plants which evolved in response to the cool, wet climate and abundant sunlight.

The Alpine-steppe is a high altitude natural alpine grassland, which is a part of the Montane grasslands and shrublands biome.. Alpine-steppes are unique ecosystems found throughout the world, especially in Asia, where they make up 38.9% of the total Tibetan plateau grassland's area.
