A new study led by the Wildlife Conservation Society (WCS) has updated the global population estimate for the Critically Endangered Grauer’s gorillas (Gorilla beringei graueri) – the world’s largest gorilla subspecies– to 6,800 individuals from a previous global estimate of 3,800 individuals.

A new study published in the journal Diversity and Distributions predicts massive range declines of Africa’s great apes – gorillas, chimpanzees and bonobos – due to the impacts of climate change, land-use changes and human population growth.
