South China Sea Marine Life Flourishes Amidst Protection Efforts
15 Aug
Summary
- Marine ecosystems in China's southern waters showed stable conditions last year.
- Coral coverage is increasing, mangroves are healthy with over 75% canopy.
- Rare species like dugongs and whale sharks sighted, indicating recovery.

Marine ecological conditions in China's southern maritime region were stable last year, with notable improvements in coral coverage and healthy mangrove ecosystems. Two reports, released on Friday, indicate coastal water quality and biodiversity remain within normal ranges. Mangrove canopy coverage exceeds 75 percent, and seagrass beds are healthy.
Efforts have led to a significant decline in red tide warnings and successful management of localized biological outbreaks. For the first time, island reef ecosystems across the Xisha, Zhongsha, and Nansha islands were comprehensively assessed, providing a basis for enhanced protection and management. Huangyan Island was identified as a vital gene bank.
Reefs on the Xisha Islands show good recovery, while Nansha Islands' reefs vary, with some healthy and others degraded due to environmental factors and human activity. Multiple sightings of endangered species, including whale sharks and dugongs, confirm improving ecological trends, with new monitoring technologies deployed.
Over 21.3 billion yuan has been invested in 262 projects during the 14th Five-Year Plan period (2021-25). By the end of 2025, marine ecological protection redline areas cover approximately 2.66 million hectares, and marine protected areas span about 7 million hectares.
