Eucalyptus plantations are essential for the viability of local communities in South Africa. Invasive pests threaten their sustainability. Gonipterus is a leaf-feeding beetle that defoliates eucalyptus trees. Conventional methods for detecting infestation are spatially restrictive. In this project, we explore the use of Unmanned Aerial Vehicles and time-series Sentinel-2 imagery to detect potential outbreaks of Gonipterus in an early stage.
