Why is the seasonal rain cycle so important to the savanna ecosystem?

However, in order for the savannas to survive, they must have the long dry periods. If it rained all year, the savannas would become tropical forests, filled with trees and tall vegetation. For grasslands to survive, they need the dry periods that prevent trees from taking over.

Drought. During the dry season, humidity is very low, causing some watering holes and rivers to dry up. This lack of water (and lack of food supply) may force many grazing animals to migrate to more fertile spots.
