我们描述的分布在沙特阿拉伯的Papio hamadryas的生态限制和最近的变化，人类活动和土地利用。狒狒只存在于Sarawat和Hijaz南部山区，这些山区与该国西南部地区的红海接壤。我们的分布数据证实，它们的分布范围，如1981年所描述的，应该向北延伸200公里，从北纬21度40分（塔伊夫）到北纬23度20分（阿哈尔）。这一新的范围限制并不是因为狒狒最近的部署，而是纠正了以前记者不准确的调查。影响狒狒分布的生态因素包括年降雨量低（每年不到100毫米），这限制了狒狒在北部和东部的活动范围，以及沿海平原缺乏合适的睡眠悬崖，这限制了它们在西部的活动范围。相对丰富度的植被和捕食者的分布进行了讨论。人类的影响也很大：狒狒部队在城市中心附近持续存在，而农业发展减少了某些地区的狒狒数量。栖息地的特点进行了讨论，在埃塞俄比亚的hamadryas的范围与类似的数据进行比较。
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.
