Savanna
Savanna
Savanna (pronounced /səˈvænə/) is a type of grassland biome characterized by the presence of scattered trees and a warm climate. The term is derived from the Taino word 'Zabana', which was later adopted by the Spanish as 'Sabana'.
Etymology
The word 'Savanna' originates from the Taino word 'Zabana', which was used to describe a grassy, treeless plain. The Spanish later adopted this term as 'Sabana'. The English language borrowed the term in the late 16th century, modifying it to 'Savanna'.
Characteristics
Savannas are typically warm year-round with two distinct seasons: a wet season and a dry season. They are characterized by a continuous cover of perennial grasses, with scattered trees or shrubs. The trees in savannas are often adapted to dry conditions and are frequently deciduous, dropping their leaves during the dry season to conserve water.
Types of Savannas
There are several types of savannas around the world, including the tropical and subtropical savannas, temperate savannas, and montane savannas. Each type has its unique characteristics and species composition.
Flora and Fauna
The flora of savannas includes a variety of grasses and trees, such as acacia and baobab trees. The fauna is diverse and includes many large herbivores, such as elephants, zebras, and various species of antelope. Predators, such as lions and cheetahs, are also common in savanna ecosystems.
