Wildlife secrets of Nigeria's last wildernessThe world's rarest chimpanzee has been captured on camera in the remote forests of Nigeria. The park is regarded as a national treasure, but its wildlife is under threat from pressures such as poaching. Researchers from Chester Zoo, working with the Nigeria National Park Service, surveyed over 1,000 square kilometres of the national park. Chester Zoo has been supporting Gashaka Gumti National Park for more than 20 years, intensifying their efforts recently to address growing threats to the park's wildlife. Chester Zoo is funding patrols for the rangers and providing training in wildlife monitoring and protection.
