Savannas: The Grassland Ecosystems of Tropical and Subtropical Regions

Savannas are a type of ecosystem characterized by grasslands with scattered trees, typically found in tropical and subtropical regions. They are often associated with the Serengeti in Africa, but they can also be found in other parts of the world, such as Australia, South America, and India.

Savannas are formed when rainfall is seasonal and unpredictable, leading to a mosaic of different vegetation types, including grasslands, shrublands, and forests. The open grassland areas provide habitat for a wide variety of herbivores, such as zebras, antelopes, and buffaloes, while the scattered trees offer shelter and food for predators like lions, leopards, and hyenas.

Savannas are also home to many other species of plants and animals, including birds, reptiles, and insects. They play an important role in supporting biodiversity and providing ecosystem services, such as carbon sequestration, soil conservation, and water regulation. However, savannas are under threat from human activities like deforestation, overgrazing, and climate change, which can lead to degradation of the ecosystem and loss of its unique biodiversity.
