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.
