The Eastern Gorilla – the largest living primate – has been listed as Critically Endangered due to illegal hunting, according to the latest update of The IUCN Red List of Threatened Species™ released today at the IUCN World Conservation Congress taking place in Hawaiʻi. Four out of six great ape species are now Critically Endangered – only one step away from going extinct – with the remaining two also under considerable threat of extinction.
The Eastern Gorilla (Gorilla beringei) – which is made up of two subspecies – has moved from Endangered to Critically Endangered due to a devastating population decline of more than 70% in 20 years. Its population is now estimated to be fewer than 5,000. Grauer’s Gorilla (G. b. graueri), one subspecies of Eastern Gorilla – has lost 77% of its population since 1994, declining from 16,900 individuals to just 3,800 in 2015. Killing or capture of great apes is illegal; yet hunting represents the greatest threat to Grauer’s Gorillas. The second subspecies of Eastern Gorilla – the Mountain Gorilla (G. b. beringei) –is faring better and has increased in number to around 880 individuals. Four of the six great apes – Eastern Gorilla, Western Gorilla, Bornean Orangutan and Sumatran Orangutan – are now listed as Critically Endangered, whilst the Chimpanzee and Bonobo are listed as Endangered.
“To see the Eastern gorilla – one of our closest cousins – slide towards extinction is truly distressing,” says Inger Andersen, IUCN Director General. “We live in a time of tremendous change and each IUCN Red List update makes us realize just how quickly the global extinction crisis is escalating. Conservation action does work and we have increasing evidence of it. It is our responsibility to enhance our efforts to turn the tide and protect the future of our planet.”
