Savannah grasslands are characterized by a mix of grasses and scattered trees. These grasslands are found in several parts of the world, but the largest and most well-known savannahs are found in Africa. Some of the key features of African savannahs include:

1. Climate: Savannahs are generally found in tropical or subtropical areas that have distinct rainy and dry seasons. In Africa, this means that savannahs are found mostly in the equatorial region, where temperatures are warm year-round and rainfall is concentrated in a few months.

2. Grasses: The grasses in African savannahs are typically tall and coarse, with tough, fibrous stems that help them survive periods of drought. Common grasses include elephant grass, Bermuda grass, and star grass.

3. Trees: While savannahs are not as densely forested as rainforests, they do have scattered trees and shrubs. In African savannahs, acacia trees and baobabs are common.

4. Wildlife: Savannahs are home to a diverse array of wildlife, including large herbivores like elephants, giraffes, and zebras, as well as predators like lions, cheetahs, and hyenas.

5. Human impacts: Like many ecosystems, African savannahs are under threat from human activities like deforestation, agriculture, and hunting. As these pressures continue to mount, the future of these important ecosystems is uncertain.

In conclusion, while savannah grasslands can be found in several parts of the world, the largest and most iconic savannahs are found in Africa. These ecosystems are characterized by a mix of grasses and scattered trees, and are home to a wide variety of wildlife. However, they are also under threat from human activities, which could have serious consequences for the future of these important ecosystems.
