As they roam around the African savanna in search for food, giraffes and elephants alter the diversity and richness of its vegetation. By studying the foraging patterns of these megaherbivores across different terrains in a savanna in Kenya, scientists from the Smithsonian Tropical Research Institute (STRI) and collaborating institutions discovered that these large mammals prefer to eat their meals on flat ground, potentially impacting the growth and survival of plant species on even savanna landscapes, such as valleys and plateaus.
