Join us in uncovering the wonders of grassland animals across the globe, a celebration of biodiversity and ecological complexity in one of the planet’s most vital and extensive biomes.
Tropical Grasslands: African Savannas
The African Savannas represent one of the most iconic grassland biomes in the world. Stretching across the continent, these savannas are characterized by a warm climate year-round, with distinct wet and dry seasons.
This biome is a vast expanse of rolling grasslands interspersed with scattered trees and shrubs, such as acacias and baobabs. The savannas are known for their rich biodiversity and are home to some of the most well-known wildlife on the planet.
The environment here supports a variety of life, adapted to both the open expanses and the seasonal changes. During the wet season, the savannas burst into life with lush grasses and abundant water, while the dry season poses challenges with scarce water and food resources.
