The western black crested gibbon (Nomascus concolor) is mainly distributed in Yunnan, China. Ailao Mountain is located in central Yunnan and divided into three prefectures and six counties. This mountain forms the principle distribution range for western black crested gibbon; however, there are no published data on the gibbon population inhabiting the Xinping administrative. Take the interview results conducted in 2007 and 2009 with local people as the reference, this study conducted an extensive field survey covering all possible habitats from November 2009 to January 2010 using call surveys. Among the one hundred and twenty-four gibbon groups which were confirmed across the Ailao Mountain, the largest known population of western black crested gibbons yet, 85 groups inhabit the national nature reserve and adjacent national forest, 30 groups inhabit the provincial nature reserve and nine groups inhabit the collective forest located outside the reserve and national forest. We found that the western black crested gibbons here have a patchy distribution pattern and occur at higher densities in certain areas. Moreover, the population distribution density and elevation gradient distribution decline from north to south. The results also demonstrated the importance of Ailao Mountain in the western black crested gibbon protection.
西黑冠长臂猿（Nomascus concolor）主要分布在中国云南。哀牢山位于云南中部，分属三个州六个县。这座山是西黑冠长臂猿的主要分布区；然而，尚无关于新平县境内长臂猿种群的公开数据。本研究以2007年和2009年对当地居民的访谈结果为参考，于2009年11月至2010年1月期间，通过鸣声调查对所有可能的栖息地进行了广泛的实地调查。在哀牢山确认的124个长臂猿群体中，这是目前已知最大的西黑冠长臂猿种群，其中85个群体栖息在国家级自然保护区及毗邻的国有林中，30个群体栖息在省级自然保护区，9个群体栖息在保护区和国有林之外的集体林中。我们发现，这里的西黑冠长臂猿呈斑块状分布模式，在某些区域密度较高。此外，种群分布密度和海拔梯度分布从北向南递减。研究结果还表明了哀牢山在西黑冠长臂猿保护中的重要性。
