The survey was done during the months of June and July 2008 by the ACNR team. The team consisted of the senior researchers based at Kigali and Karisoke. The relict forest of Buhanga is located in Musanze District in Northern Province. Buhanga, also called Gihondohondo is at 7 km from Musanze District administrative center. It is a site of depression tectonics, originally corresponding to the former Nyabarongo Valley and is bounded on the East by Bugarura (Musanze District) and west by the escarpment fault of Buhoma (Nyabihu District). Gihondohondo is a rocky site which indicates the presence of volcanic materials resulting from strombolian eruption. It is characterized by gigantic ficus and dracaena species. This forest used to serve as a place of spiritual investiture for Rwandan Kings.
