In 1889, an intrepid, 20-year-old American called William Stamps Cherry made a solo voyage up the Congos tributaries. His destination was Oubangui-Chari, a remote corner of the French Empire, in what would later become the Central African Republic (CAR). From the capital, Cherry struck out into uncharted wilderness. He was completely alone, save for a double-barreled rifle. This hunter from Missouri found a land brimming with wildlife. There is no way of estimating the number of elephants in the interior, he wrote in his journal. It may be five hundred thousand. It may be a million. I think more likely millions. Today, more than a century on, the sustained slaughter of elephants has now left fewer than 3,000 in the region, with perhaps just a few dozen in the Chinko reserve, a vast area of wildernesses in the heart of the continent, surrounded by various civil wars. Fuelled by the demand for bushmeat and ivory, decades of poaching have decimated an extraordinary mix of species. But remnant populations have endured the carnage and habitats remain intact. Conservationists are now battling to restore Chinkos swaths of rainforest and wooded savannah to their former glory. The park is managed by David Simpson, a charismatic 30-year-old from England who counts reformed poachers among his team of rangers and trackers. Ongoing conflict, however, complicates their efforts. War erupted in the country in 2013 when the Seleka-coalition of predominantly Muslim rebels-overthrew the government. The coup sparked clashes between the rebels and vigilante groups known as the Anti-balaka, in which thousands died. Fighting is again on the increase as the Seleka alliance splinters. Run by conservation non-profit African Parks, Chinko is at the centre of a humanitarian disaster. In March 2017, more than 300 civilians fled into the park to find refuge from marauding militias. Employees at Chinko offered this terrified community food and shelter, setting up a temporary camp for them deep in the savannah. At last, after more than a year in exile, these internally-displaced people have now returned home. Poachers, illegal miners and rebel militias all operate with impunity in this anarchic region. Another threat comes each dry season when cattle herders-and their thousands of cows-migrate southwards from Chad and Sudan in search of pasture. Agencies
