Situated in the valley plains over 100 m above sea levels and occupying over 80 hectares of land, Sha Lo Tung consists of large stretches freshwater wetlands, which is a well-known habitat for dragonflies in Hong Kong. To monitor the environmental changes, we continually record the distribution and population of dragonfly species in the area.
Over 70% of Lantau Island still maintains its natural form and has a very large degree of biodiversity. On the other hand, large scale development plans are being completed or in the process of being implemented, posing a threat to local habitats. Our surveys help us to gain further understanding of the dragonfly habitats and carry out conservation work of those areas.
