In this picture taken Wednesday Aug. 11, 2012, Emmanuel de Merode, Virunga National Park director and chief warden poses at the park headquarters in Rumangabo, some 60 kms (40 miles) north of Goma, eastern Congo. Virunga National Park, where virtually every rebellion in eastern Congo in the past 30 years has started, and its endangered mountain gorillas, are facing increasing threats from a new rebel group and from a decision to open Africa's oldest national park to oil exploration.Virunga now has about a quarter of the world’s remaining 790 mountain gorillas, with the others concentrated in parks in neighboring Rwanda and Uganda.
