摘要中国、老挝和越南的黑冠朱古力受到森林砍伐和栖息地破坏的威胁，但还没有关于它如何利用森林栖息地的研究，这可能是因为典型的崎岖地形和人类对该物种的害羞。2005年3月至2006年4月，我们研究了云南省无量山自然保护区边界的一个习惯性群体的森林利用。该集团花了大部分时间在原始森林，但更喜欢在二月的次生林时，Leucosceptrum canum开花。偶尔利用矮林，从不利用紫茎泽兰草地。原始森林提供了睡觉和唱歌的树木，最多的食物资源，安全的掩护和合适的运动支持。这片森林对它们的生存至关重要，但再生缓慢。尽管该地区的次生林已经再生了50多年，但它只为长臂猿提供了有限的食物资源。然而，它可能包括一个很好的走廊，供他们分散。矮树林提供了一个潜在的走廊，让这群人分散到山的另一边。无量山原始森林应禁止择伐和农业侵占。建议采用桤木、杨梅、L. canum和西南桦为恢复E.紫茎泽兰草原和扩散走廊。
Abstract The Critically Endangered black crested gibbon Nomascus concolor of China, Laos and Vietnam is threatened by deforestation and habitat destruction but there have been no studies of how it uses its forest habitat, probably because of the typically rugged topography and the species' shyness of humans. We studied the forest use of one habituated group between March 2005 and April 2006 on the border of Wuliangshan Nature Reserve, Wuliang Mountain, Yunnan, southern China. The group spent most of its time in the primary forest but preferred secondary forest in February when Leucosceptrum canum blossomed. They used dwarf forest occasionally but never used Eupatorium adenophorum grassland. Primary forest provided sleeping and singing trees, most food resources, safe cover and suitable locomotion supports. This forest is crucial for their survival but regenerates slowly. Even though secondary forest in the area has been regenerating for >50 years it provides only limited food resources for the gibbons. It may, however, comprise a good corridor for their dispersal. Dwarf forest provides a potential corridor for the group to disperse to a population on the other side of the mountain. Selective logging and agriculture encroachment should be forbidden in the primary forest on Wuliang Mountain. We recommend Alnus nepalensis, Myrica esculenta, L. canum and Betula alnoides as the pioneer species to recover the E. adenophorum grassland and for dispersal corridors.
