The looming extinction of the vaquita puts Gulf of California on World Heritage danger list | WPN World People News

In recent years, illegal fishing activities within the Gulf of California have had devastating impacts on its unique marine wildlife, pushing the vaquita to the brink of extinction. The porpoise gets entangled in gillnets used illegally to fish another Critically Endangered species, the totoaba fish, whose swim bladder fetches high prices in Asian markets.

“It is an alarming indicator of the severity of illegal wildlife trade that we may soon witness the extinction of such an iconic species as the vaquita – within the supposed safety of a World Heritage site,” says Peter Shadie, Director of IUCN’s World Heritage Programme. “Mexico’s constructive approach to the Gulf of California’s danger-listing will help mobilise action to stop this threat before it depletes more of our precious marine heritage, and IUCN stands ready to support its efforts.”

The Islands and Protected Areas of the Gulf of California became a World Heritage site in 2005 for its exceptional marine biodiversity. Composed of 244 islands, islets and coastal areas in north-eastern Mexico, the site boasts 39% of marine mammal species and a third of cetacean species in the world. The Upper Gulf of California is the only place on Earth where the vaquita is found.

In 2017, the population of vaquitas had dramatically declined from some 300 at the time of inscription to an estimated 30 animals. Attempts to breed vaquitas were quickly abandoned as the porpoise proved highly susceptible to captivity-related stress.

An international committee for vaquita recovery estimated that 10 vaquitas remained in the summer of 2018 – prior to the current fishing season. High levels of illegal fishing for totoaba continued and even escalated in 2018 and 2019 in the Upper Gulf of California, including in the small area where the few vaquitas remain.

Following two recent missions and regular monitoring, IUCN and UNESCO’s World Heritage Centre concluded that the threat of illegal fishing on the Gulf of California’s marine life justified the site’s inclusion on the List of World Heritage in Danger. The World Heritage Committee adopted this advice on July 3.

As advised by IUCN, Mexico must now undertake any means necessary to safeguard the remaining vaquitas and develop longer-term solutions to ensure sustainable livelihoods for local communities in the Gulf of California, including through improved sustainable fishing practices.

The List of World Heritage in Danger is a mechanism designed to facilitate emergency conservation action and international assistance to support severely threatened World Heritage sites.
