Passage: The Okapi Wildlife Reserve was created with the help of the Okapi Conservation Project in 1992. The project continues to support the reserve by training and equipping wildlife guards and by providing assistance to improve the lives of neighboring communities. The Okapi Wildlife Reserve was added to the list of World Heritage Sites in danger in 1997. The main threats to the reserve are deforestation, primarily caused by slash and burn agriculture, and commercial hunting for the sale of bush meat. Gold mining has also been problematic to the Reserve. As of 2005, the fighting in the eastern part of the country moved within the boundaries of the Reserve, causing its staff to flee or be evacuated. While the native Mbuti and Bantu peoples traditionally respect the forest and its wildlife, immigrants into the area do not feel the same connection to the land. Lack of funding due to the poor political and economic conditions of the Democratic Republic of the Congo has also been problematic. It is hoped that eco-tourism to the area can be developed, leading to both increased funding and improved public awareness.
