Despite its name, the Budongo-Bugoma corridor is not a migratory corridor for chimpanzees travelling between the Budongo and Bugoma Forests. A regional survey by McLennan (2008) showed that chimpanzees were resident and widely distributed throughout the corridor landscape. Based on an extrapolation of chimpanzee density for one resident community within the corridor, Bulindi, McLennan estimated a total regional population of 260 individuals. A genetic mark-recapture study conducted in 2012-2013 confirmed this approximate population size distributed broadly throughout a network of mostly unprotected forest fragments between the Budongo and Bugoma Forests (McCarthy et al., 2015). The population comprises nine or more resident chimpanzee communities (McCarthy et al. 2015, 2018). More recent work in this region has indicated declines in some of the community-specific abundance estimates reported by McCarthy and colleagues (BCCP, unpublished data).

Chimpanzees in the Budongo-Bugoma Corridor region are threatened principally by habitat loss, as remaining areas of riparian forest are logged for timber and converted for small-scale and commercial agriculture. In addition to commercially produced crops such as tobacco, rice and sugarcane (McLennan & Hill 2015), exotic timber is also widely grown, including species such as eucalyptus and Caribbean pine. Growing infrastructure, including the construction of paved roads for oil extraction, has increased the risks for chimpanzees, and chimpanzees have been killed regionally by vehicle traffic (McLennan & Asiimwe 2016; McLennan et al. 2021). Human-wildlife conflict presents another major threat to chimpanzee survival (McLennan & Hill 2012), and chimpanzees have been killed by illegal mantraps set in order to discourage crop feeding (McLennan et al., 2012; Cibot et al., 2019). Disease risk also threatens chimpanzees; this risk includes respiratory diseases as well as gastrointestinal parasites (McLennan et al., 2017; 2018).
