It is the only species of macaque that is distributed outside Asia. These animals can occupy a variety of habitats, such as cedar, fir, and oak forests, or grasslands, scrub, rocky ridges full of vegetation. Most Barbary macaques inhabit cedar forests currently in the Atlas Mountains, however, this could reflect the present habitat availability rather than a specific preference for this habitat. The diet of a Barbary macaque consists of
Crab-eating macaque durians such as "Durio graveolens" and "D. zibethinus", and are a major seed disperor for the latter species. Although the species is ecologically well-adapted and poses no threat to population stability of prey species in its native range, in areas where the crab-eating macaque is not native, it can pose a substantial threat to biodiversity. Some believe the crab-eating macaque is responsible for the extinction of forest birds by threatening critical breeding areas as well as eating the eggs and chicks of endangered forest birds. The crab-eating macaque can become a synanthrope, living off human resources. They are known to
