摘要
云南临沧邦马山是西黑冠长臂猿滇西亚种Nomascus concolor furvogaster重要分布地之一,但其种群现状一直没有系统的调查。从2013年10月至2014年1月及2014年5月,通过历时86 d对邦马山西黑冠长臂猿种群和分布现状的野外调查(包括访问调查和实地调查:鸣声定位法和样线法),首次绘制出该地区西黑冠长臂猿历史分布格局和变迁状况。西黑冠长臂猿曾广泛分布于邦马山大部分林区,数量在30群以上;20世纪60年代至20世纪末,因自然灾害、毁林开荒造成的森林破坏和猎杀导致邦马山长臂猿数量锐减至10群以下。目前,邦马山西黑冠长臂猿已从绝大部分原始分布区消失,整个邦马山仅2个地点(勐撒小邦马和芒洪大鹿山)可能分别有1群西黑冠长臂猿残存,其种群现状是西黑冠长臂猿已极为稀少,处于灭绝的边缘。调查发现,保护区内和周边林区仍存在较多的偷猎和砍伐等人为干扰现象,严重威胁残存的西黑冠长臂猿群体以及其他野生动物的生存和发展。作为澜沧江省级自然保护区的核心组分,邦马山亟需成立专门的保护区管理机构,以有效保护该地区的动植物资源和生态系统。
The western black crested gibbon （Nomascus concolor） is mainly distributed in Yunnan, China. Of the four subspecies, N. cortcolorfurvogaster is endemic to the Lincang prefecture, southwest Yunnan, however, lack of systematic surveys were conducted for the population and distribution of this species. Bangma Mountain is one of the distribution areas of N. c. furvogaster. In order to assess the status of N. concolor population in Bangma Mountain, interviews and field sur- veys were conducted by monitoring the loud morning songs and using the line-transect methods from October 2013 to January 2014 and in May 2014. The results showed that N. concolor were rare, probably only two groups survived in the discontinu- ous forest patches in Bangma Mountain because of the early natural disasters, deforestation, and heavy hunting. As one of the core areas in Lancangjiang Provincial Nature Reserve, the most important measure for wildlife protection in Bangma Mountain is to build an administrative agency and start regular monitoring to prevent any illegal activities in the reserve.
