found that the monkey's range is restricted to just 6.82 mi2 (17.7 km2) of forest in the two isolated regions, the Ndundulu forest and the Rungwe-Livingstone forest. The Ndundulu forest is the smaller of the two and was found to support a population of 75 individuals, ranging from 15 to 25 individuals per group. The Rungwe-Livingstone forest is suspected to contain 1,042 individuals in Rungwe-Kitulo, ranging from 25 to 39 individuals per group. All areas where the kipunji is found are considered protected areas, but no management operations are currently in effect. Several factors contribute to the projected decline of the species, including predation, habitat destruction, and hunting. The kipunji has only two known predators: crowned eagles (Stephanoaetus coronatus) and leopards (Panthera pardus). The biggest threats to the species come from human activities. Logging for timber and charcoal production are the most prominent threats, but locals are also known to hunt the kipunji due to its crop-destroying habits or simply as a food source. Continued habitat loss is anticipated to cause a loss of the Bujingijila Corridor that links two populations in the Mount Rungwe and Livingstone forests. The species was included in the list of "The World's 25 Most Endangered Primates" in 2006 and 2008.
