Figure 4. Nearest distances from habitats used by chimpanzees for nest building to the landscape-scale covariates.

Rivers, roads, and human settlements were considered as proxies of human disturbance. Dense canopy forests (DF) are located farther from all landscape variables, and shortest distances were obtained for habitats with a lower tree canopy cover, such as open canopy forests (OF) and savannah-woodlands (Sav).
