The term savanna comes from the Caribbean, according to the rae, where it is also stated that it is a "plain, especially if it is very extensive, without tree vegetation"; In other words, the savanna is a type of ecosystem which has the particularity of containing limited vegetation broken up by various sectors of it, with a generally arid and dry climate, also containing multiple trees and shrubs that are not larger.. This type of plain is usually found in regions with tropical climates, such as in South America, Africa and northwestern Australia, where vegetation characterized by tall grasses, shrubs and isolated trees can be found.
This type of vegetation is due to the fact that it enables sunlight to reach the ground, thus producing a herbaceous layer spread throughout it, which is mainly a series of grasslands; This greatly helps the cattle herding work practiced a lot in these territories. In the savannas you can also find a seasonal availability of water, which circulates without a particular course, providing hydration to the grasslands of those soft soils. These territories cover around 20% of the planet's land surface; of which the largest space is located in Africa.
We can find different types of savannahs that among them we can mention: the temperate savannah, characterized by a humid climate with winters that can be cold, highly fertile and dry. The mountainous savanna with high rainfall thanks to the location, especially in the African mountains. The savannah of the intertropical zone contains a not very fertile and very dry land, similar to a temperate climate, with droughts at one time of the year and with rains the rest of the year. And the Mediterranean savannah characterized by having little vegetation surrounded by a semi-arid environment with a wide fauna that ranges from lions, giraffes, elephants, tigers, etc.
