Annual fires maintain the area in a savanna caused naturally or by lightning.
 * Lightning Fires


 * Pollution in the air water and the land

During fire season, a thick pall of smoke chokes the southern Africa skies for weeks each year.


 * High temperatures

The savanna climate has a temperature range of 68° to 86° F.


 * Drought

Seasonal droughts are very common in the Savanna biome.


 * Porous soils

The soil of the savanna is porous because it drains the water especially during the wet seasons.

 Savannas are always found in warm or hot climates where the annual rainfall is from about 50.8 to 127 cm (20-50 inches) per year.
