Number of Virunga Gorillas Increased

According to monitoring data from the International Gorilla Conservation Programme and the Dian Fossey Gorilla Fund, the number of the Virunga gorillas increased from 320 to 359 individuals since the last census in 1989. The population has been slowly increasing, despite the war and conflict in the region, and the enormous threats on the habitat.
Civil unrest, armed conflict and genocide have plagued the Great Lakes region for the last 10 years. The Virunga volcanoes range has been in the centre of the fighting and the instability in the region. This forest, straddling the borders between Rwanda, Uganda and the Democratic Republic of Congo, has been repeatedly used by various armed groups as a transit corridor and a rear base for their military activities. Over the years, thousands of civilians have sought refuge in the Virungas, and many of them remained in the volcanic forest for long periods of time, relying on hunting for bush meat and small scale farming for their survival. About 15 gorillas are known to have been killed as a direct consequence of this war. Military and militia movements through the forest have certainly affected many of them, and have had a negative impact on the habitat as a whole.
From the daily monitoring of the research and tourism gorilla groups, and the sightings of wild groups, it appears that the current population stands at a minimum of 359 known gorillas. This figure is most likely an underestimate, with more individuals to be counted, and it represents a significant increase from the 1989 census. This can be directly traced to the sheer dedication of field staff operating on the ground. Park rangers and trackers, many of whom have been killed or wounded while on duty in Rwanda and Congo, have been patrolling the forest continuously throughout the years of civil unrest. This dedicated work has limited the damage to the habitat and the population of gorillas.
