[HKIE-MMNC] Volunteering for Pak Nai Restoration : Restoring Abandoned Oyster Farms into Oyster Reefs
 


Date, time & venue

2023-11-18;09:00 to 12:00;Pak Nai, Gathering Point: 鴨仔坑士多 (No.283A, Nim Wan Road, Pak Nai, Yuen Long)

Co-organized with The Nature Conservancy Habitat Management Works

Programme Highlights
Shellfish reefs are the most endangered marine habitat on the planet with an estimated 85 percent global loss. In nature, oysters naturally grow and accumulate on small reefs along intertidal mudflats, providing feeding grounds for unique species from shorebirds to tiny crabs. Deep Bay was once covered with these shellfish reefs, but centuries of human activities and development have greatly reduced this critical habitat.

If you have ever visited Pak Nai in Deep Bay, you may have noticed strange rows of oysters dotted along the shorelines of the mudflats. These vast rows of oyster clumps are actually abandoned oyster farms, and though the clumps are still alive, its unnatural configuration hinders the natural restoration of the environment. In addition, these man-made rows encroach on areas where the endangered horseshoe crab forage for food.

The now-abandoned oyster farms were built following a traditional method of planting concrete poles in concentrated rows where oysters can settle to and grow on. However, these farms have been abandoned for ten years and are no longer in use. To restore Pak Nai's natural shorelines, we will remove these poles and reconfigure them into more natural reefs. This will restore habitat for species to forage and increase biodiversity on the mudflats.
