What This Document Is
This document is a scholarly review article focusing on ecological principles governing savanna ecosystems. Specifically, it revisits existing theories surrounding the coexistence of trees and grasses in these environments. It delves into the complexities of savanna structure and function, examining the interplay between various factors that influence plant life within these biomes. The work originates from research conducted at the University of California, Berkeley as part of a Directed Group Study course (ESPM 298).
