In addition to the “tourism groups”, other gorilla groups have also been habituated for scientific research. Several of them were already habituated by Dr. Dian Fossey and her teams. These groups are normally not open for visitors. They are followed on a daily basis by researchers and trackers of the Karisoke Research Centre, who spend more time with the gorillas but ordinarily not approach them as close as tourists do. The permanent monitoring to these research groups is part of the long term study of mountain gorillas in Volcanoes National Park, which has made the Virunga gorillas one of the best studied wildlife species in the world.
The groups are :
- Pablo group (44 gorillas in September 2010)
- Kuryama group (15 gorillas in September 2010 )
- Ugenda group (14 gorillas in September 2010 )
- Ntambara group (11gorillas in September 2010 )
- Isabukuru group ( 11 gorillas in September 2010 )
- Bwenge group ( 10 gorillas in September 2010 )
- Inshuti group ( 6 gorillas in September 2010 )
- Titus group ( 6 gorillas in September 2010 )
