Protection Sought for Critically Endangered Taiwanese Humpback Dolphin

WASHINGTON— Three U.S. conservation groups petitioned the federal government today to protect Taiwanese humpback dolphins under the Endangered Species Act to help prevent the extinction of a population that now numbers fewer than 75. The petition, from the Animal Welfare Institute (AWI), the Center for Biological Diversity and WildEarth Guardians, calls for the National Marine Fisheries Service to encourage Taiwan to address pollution, illegal fishing, boat traffic and other threats these small dolphins face in the shallow waters along Taiwan’s densely populated west coast.

“This small population of dolphins is in serious trouble,” said Dr. Naomi Rose, AWI marine mammal scientist. “Once it disappears, it is gone forever. The U.S. should do everything it can, including listing it under the ESA, to prevent this from happening.”

The Taiwanese humpback dolphin, also known in Taiwan as Matsu’s fish, is a biologically and culturally important subspecies of Indo-Pacific humpback dolphin, and one of many small cetaceans around the world facing imminent extinction. In 2014 the Service denied a previous petition to protect the Taiwanese humpback dolphin under the Endangered Species Act, concluding that the population was not distinct from the Chinese white dolphin that swims in deeper waters closer to China’s coastline. New taxonomy studies, however, conclude that the Taiwanese humpback dolphin is a distinct subspecies with unique characteristics whose numbers continue to decline to alarmingly low levels.   

“The Taiwanese humpback dolphin could vanish within our lifetimes if help doesn’t very come soon,” said Dr. Abel Valdivia, an ocean scientist with the Center for Biological Diversity. “Sadly, small cetaceans around the world are in trouble. We saw the baiji go extinct in China, and now the vaquita in Mexico and the Taiwanese humpback dolphin are barely hanging on.”

“Even though more than half of marine species may be at risk of extinction by 2100, only about 6 percent of species listed under the ESA are marine,” said Taylor Jones, endangered species advocate at WildEarth Guardians. “The Service needs to actively combat the current extinction crisis by quickly protecting species like the Taiwanese humpback dolphin.”

The Endangered Species Act is an effective safety net for imperiled species: Extinction has been prevented for more than 90 percent of plants and animals under its care. Scientists estimate that 227 species would have gone extinct by 2006 if not for the Act’s protections. Protecting species with global distributions can help focus U.S. resources toward enforcement of international regulations and recovery of the species.
