Abstract

The rare Himalayan wolf Canis lupus chanco is categorized as Vulnerable on the IUCN Red List, and there is limited knowledge of its ecology and distribution. In Bhutan, the Himalayan wolf is one of the least known carnivores. Our aims in this study were to map the current distribution of the wolf in Bhutan and to identify potential habitats within the country. We compiled 32 records of wolf presence from camera-trap surveys and, using a maximum entropy approach, we estimated a potential habitat of 2,431 km2, comprising c. 6.3% of Bhutan. However, wolf presence was localized and non-continuous. We recommend a detailed fine-scale habitat analysis in areas of potential habitat and genetic studies to investigate population structure. Knowledge of these matters will provide insights regarding connectivity and facilitate the development of conservation strategies for this threatened wolf.

不丹境内易受攻击的喜马拉雅狼 Canis lupus chanco 的分布和潜在栖息地
稀有的喜马拉雅狼(Canis lupus chanco)在《世界自然保护联盟红色名录》中被列为易危物种,人们对其生态和分布的了解十分有限。在不丹,喜马拉雅狼是已知最少的食肉动物之一。我们此次研究的目的是绘制不丹狼目前的分布图,并确定其在不丹的潜在栖息地。我们汇编了 32 份相机捕获调查中发现的狼的存在记录,并使用最大熵方法估算出 2431 平方公里的潜在栖息地,约占不丹国土面积的 6.3%。但是,狼的存在是局部的,而且不连续。我们建议对潜在栖息地区域进行详细的精细栖息地分析,并开展遗传研究以调查种群结构。对这些问题的了解将有助于深入了解狼群的连通性,并有助于为这种濒临灭绝的狼制定保护战略。
