Chester Zoo
One of the incredibly rare chimps pictured in Nigeria
A trip into some of Nigeria's most remote forests has raised hopes for the survival of the world's rarest chimp.
The Nigeria-Cameroon chimp has been pictured by cameras set up at various locations within Gashaka Gumti National Park, which sits along the border of the two countries.
The team of researchers from Chester Zoo, who were working with the Nigeria National Park Service, also recorded the first sighting in the country of a giant pangolin.
It is a hugely exciting find, says Stuart Nixon, the Africa Field Programme Co-ordinator at Chester Zoo: It's an incredible tool to use these camera traps and to reveal that this park - which is a forgotten wilderness, really, for Nigeria - still has a really important reservoir of important species for Nigeria and Africa in general."
