Survey

Hong Kong is home to over 260 butterfly species, accounting for one-tenth of all butterfly species in China. We collect butterfly data in various hotspots across Hong Kong to build up Hong Kong Butterfly Inventory. Through the surveys, we are able to effectively monitor environmental change and expose environmental damage at the earliest opportunity.

On the other hand, there are still many butterfly rich areas in Hong Kong yet to be discovered. Our survey helps to find out these areas so that we can protect the valuable butterfly habitats.

By making use of the concept of “citizen scientist”, we train the public to become Butterfly Surveyors and participate in butterfly conservation first hand. They are important human resources for local conservation in the long run.

The collected data is used to build up Hong Kong Butterfly Inventory, which allows the public to monitor butterfly hotspots together.
