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.
Grazing animals, herd animals, and predators in grasslands, like lions and cheetahs live in the grasslands of the African savanna. [19] Mites, insect larvae, nematodes, and earthworms inhabit deep soil, which can reach 6 metres (20 feet) underground in undisturbed grasslands on the richest soils of the world.
Grass consumption in dogs can be a way to rid their intestinal tract of parasites that may be threatening to the carnivore's health. [3] Various invertebrates also have graminivorous diets. Many grasshoppers , such as individuals from the family Acrididae , have diets consisting primarily of plants from the family Poaceae. [ 4 ]
The tropical and subtropical grasslands, savannas, and shrublands are characterized by rainfall levels between 90–150 centimetres (35–59 in) per year. [1] Rainfall can be highly seasonal, with the entire year's rainfall sometimes occurring within a couple of weeks. African savannas occur between forest or woodland regions and grassland regions.
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.
