HONG KONG, May 19, 2025 /PRNewswire/ -- The Nature Conservancy (TNC) is calling on the public to voice their support for greater marine conservation in Hong Kong's updated Biodiversity Strategy and Action Plan (BSAP), which is now open for public consultation for the coming two months. In light of the government's commitment to update the BSAP by the end of 2025, TNC urges the Agriculture, Fisheries and Conservation Department (AFCD) to include robust measures to protect and restore vital coastal ecosystems – particularly oyster reefs – which are among the most endangered marine habitats globally.
Despite Hong Kong's rich marine biodiversity – home to over 5,900 species, or more than one-quarter of all marine species recorded in mainland China – marine conservation efforts have lagged far behind those on land. Only about 6% of Hong Kong's marine waters are protected, well below the global target of 30%. Many ecologically important habitats, including oyster reefs, remain outside of protected areas and face persistent threats, particularly in western waters.
Oyster reefs and other shellfish reefs deliver vital benefits to people and the planet, including providing habitat for marine life, supporting fish production, regulating water quality and protecting coastlines. Yet, over the past two centuries, more than 85% of the world's shellfish ecosystems have been lost. Hong Kong is no exception. Historical dredging, reclamation, and urban development have decimated once-abundant oyster habitats across the territory. Today, any remaining oyster reefs are not officially recognised as ecologically important, are unprotected and therefore highly vulnerable to ongoing harvesting, degradation and reclamation projects, including the proposed Kau Yi Chau Artificial Islands, which do not take shellfish reefs into account when conducting the Environmental Impact Assessment.
"Ecological restoration presents a huge opportunity for nature and people. However, ecological restoration is not without its challenges, that's why it cannot replace nature conservation, and should never be used to justify the destruction or degradation of ecosystems", said Marine Thomas, Associate Director of Conservation, The Nature Conservancy Hong Kong (TNC).
"The health of our marine ecosystems is crucial for a sustainable future," said Professor Bayden Russell, from the Swire Institute of Marine Science (SWIMS), The University of Hong Kong. "We must act now to restore our oyster reefs and protect our biodiversity."
With the BSAP now under review, the public has a once-in-a-decade opportunity to advocate for stronger marine conservation policies and the health of Hong Kong waters. TNC will be submitting formal recommendations to AFCD and encourages the public to take part by submitting their views before the deadline on July 11, 2025.
TNC's Key Recommendations for the BSAP
To reverse biodiversity loss and strengthen coastal resilience, TNC recommends that the updated BSAP prioritize the following:
"This is a critical opportunity to share your voice in shaping the future of Hong Kong's marine environment. We stand at a crossroads; if we act now, we can bring back these once abundant ecosystems, securing cleaner water, healthy fisheries, and stronger coastlines for future generations, or we continue to destroy our oceans, possibly to a point of no return", said Marine Thomas, Associate Director of Conservation at TNC.
TNC urges members of the public to participate in the BSAP consultation by emailing directly AFCD at bsap@afcd.gov.hk or visiting AFCD's dedicated website: https://www.afcd.gov.hk/english/conservation/Con_hkbsap/updating_bsap/updating_bsap.html for details on proposed updates to Hong Kong Biodiversity Strategy and Action Plan. The public consultation is open from May 12 to July 11, 2025.
To learn more about oyster reefs and why they matter to Hong Kong, TNC is featured in the documentary "City of Shells: Our Forgotten Oyster Reefs," which explores the ecological, cultural, and historical significance of these lost ecosystems – and the opportunity to restore them. Watch the documentary at www.cityofshells.com, or visit the exhibition "Reviving Hong Kong's Ocean Heritage: Our Forgotten Oyster Reefs" at Pacific Place from 29 May to 11 June for more details.
