The Annamite mountains of Viet Nam and the Lao People's Democratic Republic (Lao) are an area of exceptional mammalian endemism but intensive poaching has defaunated much of the region, creating an extinction crisis for the endemic species. To make efficient use of limited conservation resources, it is imperative that conservation stakeholders obtain basic information about poorly known and threatened endemics. We present the first comprehensive information on the ecology, distribution and status of the little-known endemic Annamite striped rabbit Nesolagus timminsi. We used a systematic camera-trapping design to study the species in five areas in Viet Nam and Lao. In 29,180 camera-trap-nights we recorded 152 independent events at 36 of 266 stations. We obtained an additional 143 independent detections across 12 stations from a supplementary non-systematic survey. We analysed activity patterns and social behaviour. We also used single-species occupancy models to assess factors that influence occupancy at the landscape scale. We used N-mixture models to obtain local abundance estimates in one target area. The Annamite striped rabbit was found to be nocturnal and primarily solitary. Species occupancy was best explained by a proxy for past hunting pressure, with no significant relationships to current anthropogenic or environmental factors. Local abundance was 0.57 individuals per camera-trap station for one of our sites, and estimated to be zero at the other site where hunting appears to have been more intense. Our results provide information on priority areas for targeted anti-poaching efforts and give the first conservation baseline for the species.

陷入东南亚灭绝危机的鲜为人知的地方病:安南条纹兔 Nesolagus timminsi

越南和老挝人民民主共和国 (Lao) 的 Annamite 山脉是一个特殊的哺乳动物特有地区,但密集的偷猎已经使该地区的大部分地区失去了生态系统,给当地物种造成了灭绝危机。为了有效利用有限的保护资源,保护利益相关者必须获得关于鲜为人知和受威胁的地方病的基本信息。我们首次提供了关于鲜为人知的地方性安南条纹兔的生态、分布和状况的综合信息Nesolagus timminsi。我们使用系统的相机捕捉设计来研究越南和老挝五个地区的物种。在 29,180 个相机陷阱之夜,我们在 266 个站点中的 36 个记录了 152 个独立事件。我们通过补充的非系统调查在 12 个站点中获得了额外的 143 次独立检测。我们分析了活动模式和社会行为。我们还使用单一物种占用模型来评估影响景观尺度占用的因素。我们使用 N 混合模型来获得一个目标区域的局部丰度估计值。Annamite条纹兔被发现是夜间活动的,主要是孤独的。物种占有最好用过去狩猎压力的代理来解释,与当前的人为或环境因素没有显着关系。局部丰度为 0。我们的一个站点的每个相机陷阱站有 57 个人,而在另一个狩猎似乎更加激烈的站点估计为零。我们的结果为有针对性的反偷猎工作提供了有关优先领域的信息,并为该物种提供了第一个保护基线。
