Ancient Chinese Poetry Reveals 65% Decline in Yangtze Finless Porpoise Habitat
- Researchers published on May 5 in Current Biology that ancient Chinese poems reveal a 65 percent decline in the Yangtze finless porpoise habitat since around 618 AD.
- Scientists analyzed 724 verified poems mentioning the porpoise to overcome scarce official records and chart its historical range along the Yangtze River in China.
- The Yangtze finless porpoise, a critically endangered freshwater species with about 1,250 wild individuals, has lost 91 percent of its range in tributaries and lakes over 1,400 years.
- Yaoyao Zhang explained that analyzing historical data helps identify when population decreases started and link those trends to possible causes such as habitat loss, climate shifts, excessive hunting, diseases, or the arrival of non-native species.
- The research suggests that historical texts can improve understanding of species decline timing and causes, and Zhang's team plans to further explore poems for past river conditions and porpoise behavior.

Ancient Chinese poems document decline in endangered river porpoise
“Porpoises chased moonlight on silvered tides, as dragons summoned storm-clouds loom in sight,” wrote Qianlong, prolific poet and emperor of the Qing Dynasty, on a trip down the Yangtze River around 1745. He was referencing a sighting of the Yangtze finless porpoise (Neophocaena asiaeorientalis). But little did Qianlong know that more than 300 years later, this porpoise species would be critically endangered, and scientists would draw on his poe…
