WOS:A1992JA86200001. International audience. We describe the distribution of Papio hamadryas in Saudi Arabia in relation to ecological constraints and recent changes in human activities and land use. Baboons are present only in the Sarawat and southern Hijaz mountains, which border the Red Sea in the southwestern region of the country. Our distribution data confirms that their range, described as of 1981, should be extended 200 km northward, from 21-degrees-40N (Taif) to 23-degrees-20N (Al Akhal). This new limit of range is not due to recent deployment of the baboons, but instead corrects inaccurate surveys by previous reporters. Ecological factors that affect baboon distribution include low annual rainfall (less than 100 mm per yr), which limits baboon range in the north and east, and the absence of suitable sleeping cliffs in the coastal plain, which limits their range in the west. Relative abundance is discussed in relation to vegetation and predator distribution. Human influence is also significant: commensal troops persist near urban centers, while agricultural development reduces baboon numbers in some regions. Habitat characteristics are discussed in comparison with similar data on the range of hamadryas in Ethiopia.
