DRONES AND AERIAL METHODS Drones are flying devices that can be controlled from the ground using a remote control to push elephants out of farms towards safety. They are a high-cost, high-tech solution that allows rangers/authorized persons to rapidly respond to mitigate conflict to protect both humans and elephants.
Flying drones sound like a swarm of bees. When elephants are faced with a moving, flying drone that sounds like a swarm of bees, they will quickly move out of an area away from the direction of the sound. Scientists have known for years that drones flown too close to wildlife, elephants included, have the capacity to disturb and even direct them towards a given point. Hahn et al. confirmed this in their 2017 case study, showing with a 100% success rate that elephants can be effectively chased from areas with human-elephant conflict using drones. Drones can be used to capture videos and photos as well, which allows researchers to understand elephant movement and behaviour, hence helping to mitigate conflict.
