There has been a war in the DRC in different levels of intensity since 1994 when the country was called Zaire. Although what was known as Africa's World War had ended in 2003 the eastern part of the country still has ongoing skirmishes between rebel groups and government forces. No other method has reduced species population so dramatically than conflict, when a militia reached the Garamba National Park in 1997, within three months half of the park's elephants, two thirds of the buffalo, and three quarters of its hippos vanished. The reason conflict is so damaging to wildlife is the increased use of bush meat to feed soldiers, the prevalence of weapons, the lucrative industry of selling exotic animals and ivory as well as the general failure of law and order. According to another study which was taken during the time of the civil war in the Okapi Faunal Reserve, there was a 50% reduction in the abundance of elephants and a vast change in the distribution of them to the more secluded areas of the park.
