Do Elephants Eat More Trees When Less Grass Is Available? A Field Study In Kruger National Park, South Africa., Emily Goldberg
Yale Day of Data
Although African bush elephants are often responsible for the majority of herbivore-driven savanna tree mortality, confusion remains regarding the factors that influence their diet. Some elephants either browse or graze almost exclusively, while others balance the two, and the determinants of this variation remain poorly understood. I seek to determine whether grass availability controls the proportion of woody plants in elephant diet and, therefore, the amount of damage elephants do to trees while foraging. Preliminary analysis using already-available data on grass biomass, elephant density, and elephant damage to trees suggest that tree damage is in fact negatively correlated with grass …
