Record Sea Turtle Nesting Season Unfolds in Sansha City
A rare conservation success story is emerging from the waters off China’s southern coast. Nearly 100 sea turtle nests have been recorded in Sansha City’s Xisha Sea Area so far this year—marking a significant moment for marine biodiversity in the South China Sea.
Green Sea Turtles Make a Return to North Island
North Island, China’s largest natural spawning ground for green sea turtles, is currently at the height of breeding season. Patrol officers recently spotted a female green sea turtle laying eggs on the island, one of nearly 100 such discoveries so far in 2025.
Patrol Efforts Key to Nesting Site Monitoring
“Right now, we have four active nests,” said Zhong Jiangtao, a patroller from Xisha Binhai Community. “The first was laid on June 13, and with an incubation period of 45 to 50 days, hatching is expected soon.”
New Nesting Grounds Discovered at Yongshu Reef
In another exciting development, a green sea turtle nesting site was discovered on Yongshu Reef in the Nansha Sea Area. The finding confirms that this region’s ecological conditions can support endangered species and adds a new chapter to China’s growing marine conservation efforts.
AI-Powered Protection Around the Clock
To ensure the survival of this endangered species, Sansha City has deployed a scientific protection system. The number of AI-powered surveillance cameras has increased from 6 to 14, offering full coverage of all potential nesting sites. Staff also employ infrared monitoring and intelligent tracking to observe turtle behavior in real time.
Unique Genetic Lineage Connects Oceans
According to researchers at the Hainan Field Science Observation and Research Station, the green sea turtles in the Xisha Sea Area represent a distinct geographic population with unique genetic traits. Their genetic diversity plays a key role in linking turtle populations between the Pacific and Indian Oceans, making their conservation a global priority.
