Dugong, coral, abalone face extinction threat, IUCN says

Populations of a vulnerable species of marine mammal, numerous species of abalone and a type of Caribbean coral are now threatened with extinction, an international conservation organization said Friday.

The International Union for Conservation of Nature announced the update during the United Nations Convention on Biological Diversity, or COP15, conference in Montreal. The union's hundreds of members include government agencies from around the world, and it's one of the planet's widest-reaching environmental networks.

The IUCN uses its Red List of Threatened Species to categorize animals approaching extinction. This year, the union is sounding the alarm about the dugong — a large and docile marine mammal that lives from the eastern coast of Africa to the western Pacific Ocean.

The dugong is vulnerable throughout its range, and now populations in East Africa have entered the red list as critically endangered, IUCN said in a statement. Populations in New Caledonia have entered the list as endangered, the group said.

The major threats to the animal are unintentional capture in fishing gear in East Africa and poaching in New Caledonia, IUCN said. It also suffers from boat collisions and loss of the seagrasses it eats, said Evan Trotzuk, who led the East Africa red list assessment.

“Strengthening community-led fisheries governance and expanding work opportunities beyond fishing are key in East Africa, where marine ecosystems are fundamental to people’s food security and livelihoods,” Trotzuk said.

The IUCN Red List includes more than 150,000 species. The list sometimes overlaps with the species listed under the U.S. Endangered Species Act, such as in the case of the North Atlantic right whale. More than 42,000 of the species on the red list are threatened with extinction,...
