The Medog in southeastern Tibet is home to a diverse range of wild animals. However, research on these mammals' species directories, distribution, and conservation status remains insufficient, despite their crucial role in maintaining ecological balance. The study carried out a camera-trapping survey to assess mammal biodiversity and the significance of mammal protection in their natural habitats in Gedang, Medog. Future directions and application prospects of the study for wildlife conservation in the southeastern Tibetan mountains were also discussed. The survey, spanning from April 2023 to May 2024, with 19,754 camera trap days, revealed 25 mammalian species across five orders and 14 families. Among these, four classified as Endangered, five as Vulnerable, two as Near Threatened on the IUCN Red List, nine were categorized as Critically Endangered or Endangered on the Red List of China's Vertebrates, and seven were China's national first-class key protected wildlife. The order Carnivora exhibited the highest diversity, comprising 12 species. Furthermore, the study filled the knowledge gap regarding the underrepresentation of Gongshan muntjac in IUCN and provided new insights into the recorded coexistence of the Himalayan red panda and Chinese red panda along the Yarlung Zangbo River for the first time, and also documented new upper elevation limits for four large to medium-sized species. Regarding the relative abundance indices (RAI) captured by camera traps, the most prevalent species identified was the White-cheeked macaque , followed by the Gongshan muntjac and Himalayan serow . The monitoring also captured a number of domestic dogs and livestock, as well as human disturbances. These findings underscore the importance of conserving these mammals and emphasize the need for conservation efforts to protect their habitats and reduce human activities that threaten their survival, thereby maintaining the ecological balance of the region. Additionally, the research highlighted Gedang's significance to global conservation efforts for mammalian diversity, providing essential data for effective wildlife conservation strategies.
西藏东南部的墨脱是多种野生动物的家园。然而，尽管这些哺乳动物在维持生态平衡方面发挥着关键作用，但对它们的物种名录、分布和保护状况的研究仍然不足。该研究开展了一项相机陷阱调查，以评估格当（墨脱县的一个地方）自然栖息地中哺乳动物的生物多样性以及哺乳动物保护的重要性。还讨论了该研究在藏东南山区野生动物保护方面的未来方向和应用前景。这项从2023年4月持续到2024年5月、相机陷阱天数达19754天的调查，共记录了5目14科的25种哺乳动物。其中，4种在世界自然保护联盟（IUCN）红色名录中被列为濒危物种，5种为易危物种，2种为近危物种，9种在中国脊椎动物红色名录中被列为极危或濒危物种，7种为中国国家一级重点保护野生动物。食肉目物种多样性最高，有12种。此外，该研究填补了贡山麂在IUCN中代表性不足的知识空白，首次为记录到喜马拉雅小熊猫和中华小熊猫在雅鲁藏布江沿岸共存提供了新见解，还记录了4种大中型物种的新海拔上限。关于相机陷阱捕捉到的相对丰富度指数（RAI），最常见的物种是白颊猕猴, 其次是贡山麂和喜马拉雅鬣羚。监测还捕捉到了一些家犬和家畜以及人类干扰。这些发现强调了保护这些哺乳动物的重要性，并强调需要进行保护工作以保护它们的栖息地，减少威胁它们生存的人类活动，从而维持该地区的生态平衡。此外，该研究突出了格当对全球哺乳动物多样性保护工作的重要性，为有效的野生动物保护策略提供了重要数据。
