Biomes ‒ Savanna

**Savanna** is a biome located in tropical and subtropical regions of Earth, characterized by a warm climate with alternating periods of rain and drought. Based on precipitation levels and drought duration, savannas are classified into wet, dry and thornbush types. As distance increases from the equator, the dry season becomes longer, which influences the character of the vegetation. Grasses and shrubs with scattered trees predominate, all of which are well-adapted to prolonged drought. These plants have deep roots to reach groundwater, trunks or underground bulbs capable of storing water, and thick bark to withstand fires. Many plants also have defenses against grazing animals, such as thorns, thick coverings, or chemicals that make their leaves taste unpalatable. Animals in the savanna have also adapted to these conditions: mammals often have long legs for traveling long distances, and both predators and herbivores have body camouflage to blend into their surroundings. Savannas are primarily found in Africa, South America (the wetter areas known as llanos and the drier as campos), and northern Australia. African savannas are especially renowned for their diverse wildlife.
