Let’s Explore Hong Kong Butterflies Together

Tiny but mighty, Hong Kong houses more than 260 species of butterflies, which is a tenth of all butterfly species in China. Around 40% of land in Hong Kong is designated as country parks that is protected by law. However, many prime butterfly areas in the “Butterfly Paradise” are yet to be properly protected.

Established in 2008, “Butterfly Surveyor” is the first Butterfly Surveyor group that comprises members of the public from diverse sectors. Providing long-term substantial human resources for butterfly survey, the group takes regular visits to various local butterfly hotspots. After sessions of extensive and on-site training, surveyors are qualified as specialists in butterfly and ecological data collection.

Through conducting butterfly surveys, we aim at expanding local butterfly inventory, exploring more local un-protected butterfly hotspots, thus monitoring the dynamic relations between local butterfly species and environmental changes.

Until 2019, “Butterfly Surveyor” has 361 qualified members, who have been monitoring regularly at 11 designated sites, namely, San Tau – Lantau Island, Luk Keng – North District, Wu Kau Tang – Tai Po, Yuen Tun Ha – Tai Po, Sha Tau Kok – North District, Sham Chung and Yung Shue O – Sai Kung, Pak Sha O and Lai Chi Chong – Sai Kung, Mui Wo – Lautau Island, Tong Fuk and Shui Hau – Lantau Island, Tai Lam Country Park (Kam Tin) and Lung Kwu Tan - Tuen Mun. All the survey data is uploaded to Hong Kong Butterfly Inventory, members of the public can join hands to monitor conditions of butterfly hotspots.

The programme opens to general public. Each year, “Butterfly Surveyor” programme recruits members of the public as new members. After the completion of trainings and assessments, they will be qualified as “Butterfly Surveyors”. Registration for Butterfly Surveyor 2020 has been closed. Details for the next recruitment will be announced in January 2021. Stay tuned to this website for further details.
