In the grasslands, trees do not replace the grasses as a part of an ecological succession primarily due to water limits and fire. Grasslands are characterized by periodic droughts and fires, which create an environment unsuitable for the establishment and growth of trees. The limited water availability and the frequent occurrence of fires prevent the growth of trees and favor the dominance of grasses in these ecosystems.
