In 'world's bonobo stronghold' rangers and pristine forest sustain a stable population

Scientists now know how many bonobos live in one of the largest pristine tropical forests, a place believed to be the world's stronghold for the endangered species. The research estimates that between 8,000 to 18,000 adult bonobos inhabit Salonga National Park in the DRC. Although the population has remained stable since 2000, there are signs of potential decline.
