ABSTRACT

This report summarises the current state of knowledge on the distribution, densities and trends in abundance of Grauer’s gorilla (Gorilla beringei graueri) and the eastern chimpanzee (Pan troglodytes schweinfurthii) in eastern Democratic Republic of Congo (DRC). It summarises the historical knowledge about the distribution of Grauer’s gorilla across its range and describes the development of a Conservation Action Plan (CAP) for these two ape species. A result of this CAP was funding to undertake an assessment of the current status of these apes across the range of Grauer’s gorilla. Wildlife Conservation Society (WCS) and Fauna & Flora International (FFI) worked with Institut Congolais pour la Conservation de la Nature (ICCN) and the Reserve managers of the Reserve des Gorilles de Punia (RGPU) and local communities to undertake surveys across the region using a variety of methods: line transects, recces along paths and patrol data from data collected by rangers while on patrol and entered into SMART software.
