A recent report has unveiled the condition of the coral reef ecosystem at Xianbin Jiao, part of China's Nansha Qundao, revealing that it remains largely healthy with some localized damage. Conducted between May and July 2024 by several prominent research institutions, the survey assessed the reef's state, discovering that the coral coverage area is stable, accommodating 236 species of reef-building corals categorized into 57 genera and 13 families. The average coral coverage rate was found to be 24.7 percent, with peaks reaching up to 51.3 percent, a level deemed relatively strong in comparison to other global coral reef regions.

In addition to the healthy coral colonies, the survey noted a rich diversity of marine life in the area. Xianbin Jiao boasts 179 species of reef fish belonging to 26 families, such as wrasses and clownfish, with an average density approximating 124 fish per 100 square meters. While no widespread coral bleaching or proliferation of environmental threats has been reported, some local corals face risks from crown-of-thorns starfish, fleshy macroalgae, and various human activities.

Geographically, Xianbin Jiao comprises six cays, three of which are visible at high tide. Evidence of coral debris and damaged reef structures surrounds these cays, yet no land-based pollutants have been identified in the sediment samples taken from nearby waters. To augment the data collected, 34 additional survey stations were established, which together evaluated 75 factors across coral communities, organisms, habitats, and human influences on the ecosystem.

Among the remarkable observations were the presence of giant clams, horned helmets, green sea turtles, hawksbill turtles, and spinner dolphins, reinforcing the overall health of the environment. Located to the east of Ren'ai Jiao and under the oversight of Sansha City in Hainan Province, Xianbin Jiao, frequently referred to as "fish scale" by local fishermen, is primarily underwater with steep gradients and sudden depth increases along its edges. Experts have pledged to enhance their survey efforts and commence protective measures to mitigate adverse impacts from human interaction and other external threats, aspiring to uphold the coral reef's diversity, stability, and sustainability.
