Located in the southwest, Lantau Island is the biggest island in Hong Kong with an area spanning 14,400 hectares. Over 70% of Lantau Island’s natural landscape still remains, along with a high degree of biodiversity. However, its precious ecology is threatened by many large-scale developments being implemented or planned.
Since 2015, we have carried out several dragonfly ecological surveys to better understand the status of dragonflies and environmental changes on Lantau Island.
