How do elephants change the ecosystems where they live?

Elephants act as significant ecological engineers, substantially affecting and altering the ecosystems they inhabit through their daily activities and massive consumption of resources.12

Key ways they influence their environment include:

• Vegetation Management: By consuming or crushing small trees and plants, elephants thin out dense vegetation. This process increases the availability of sunlight, water, and soil nutrients for the remaining plant life.3
• Seed Dispersal: As herbivores, elephants ingest large quantities of fruit. They play a vital role in plant survival by dispersing seeds through their dung, which acts as a natural fertilizer and deposits the seeds far from the original source.3
• Landscape Modification: Elephants use their tusks to excavate and clear areas, such as the forest patches known as bais in Central Africa, which provide essential access to minerals and water for themselves and other wildlife.3
• Resource Consumption: An adult elephant consumes approximately 100 kg of food and 100 liters of water daily, with these amounts potentially doubling for an individual, which exerts a profound impact on the local environment.12
