The dense montane rainforest in the Virunga National Park is one of the last remaining habitats of the endangered mountain gorillas. Virunga is located in the eastern part of the Democratic Republic of the Congo and is the oldest national park in Africa. The park, about twice the size of Rhode Island, and along the shores of Lake Edward, was designated a World Heritage Site by the UNESCO. In addition to the gorillas, it is home to other endangered species. Now the national park, the gorillas and the people living along the lake face an existential threat.
