Since then, few attempts were made to characterize these populations. The mountain and lowland populations of Kahuzi-Biega are not in reproductive contact but effectively severed. Gorillas were no longer present in some of the regions noted by Emlen and Schaller. There have been reports that many gorillas were killed in the chaos after the civil war. In the lowland sector Grauer's gorillas are also no longer as widely distributed as they were during the time of Emlen and Schaller.
Reports indicate heavy hunting of gorillas within the Kasese region.
In the Maiko National Park, the westernmost population is extinct. The northern population has been relatively stable in recent years, and the southern population suffers from poaching and habitat pressure. North of the Lowa river an additional population has recently been confirmed. It is at risk because of its small size and isolation. The 9 subpopulations in the Itombwe Forest can be pooled into 4 populations that are reproductively isolated from one another by large rivers.
