Six rhinos were reintroduced to Chad's Zakouma National Park in Central Africa, on May 4, 2018. Due to an institutional cross-country collaboration between the Chadian and South African governments, the black rhinoceros, once locally extinct in Chad, returned to the country. /VCG Photo

Chad has experienced a dramatic decrease in poaching since 2010, with the local elephant population increased for the first time in the last decade. The country was once the home to at least two rhinoceros species, both of which became locally extinct due to over poaching. /VCG Photo

The Republic of Chad signed an agreement with the African Parks Network (APN) which allows APN to manage the country’s national parks. /VCG Photo
