Primates are the mammals of the order Primate that is characterized by advanced development of binocular vision and enlargement of the cerebral hemispheres. The aim of this study was to investigate the abundance, diversity, and distribution of primates on Welel Mountain. From August 2017 to February 2018, we collected data from different parts of Welel Mountain during wet and dry seasons of the year and analyzed them using SPSS version 20. We identified four primate species: and . We conducted -test analysis for abundance and distribution of primates in wet and dry season of the year, and the value obtained was 0.20. The mean percentages of primates in forest, woodland, and shrubs were 43.16%, 32.26%, and 24.58%, respectively. Shannon-Wiener diversity index (H') value was higher in wet season than in dry season. The current study showed that the species are distributed more evenly in wet season than in dry season, and the number of young individuals is more than that of adults. This indicates that currently the status of primates population on Welel Mountain is good. Therefore, to keep the status of primates in the study area effective, wildlife management and conservation policy should be formulated.
灵长目动物是灵长目哺乳动物的特征，其特征是双眼视觉的高度发达和大脑半球的扩大。本研究旨在调查韦雷尔山灵长类动物的丰度、多样性和分布情况。2017 年 8 月至 2018 年 2 月，我们在一年的干湿两季从韦雷尔山的不同地区收集数据，并使用 SPSS 版本 20 对其进行分析。我们确定了四种灵长类动物： 和 。我们对干湿两季灵长类动物的丰度和分布进行了检验分析，得到的 值为 0.20。灵长类动物在森林、林地和灌木丛中的平均百分比分别为 43.16%、32.26%和 24.58%。湿季的香农-威纳多样性指数（H'）值高于干季。本研究表明，与干季相比，灵长类动物在湿季的分布更加均匀，幼年个体的数量多于成年个体。这表明目前韦雷尔山灵长类动物的种群状况良好。因此，为了保持研究区域内灵长类动物的地位，应该制定野生动物管理和保护政策。
