20 世纪 90 年代末，在中俄边境发现了濒危东北虎（Panthera tigris altaica）的零星目击事件，引发了通过恢复长白山潜在适宜栖息地来扩大该亚种分布和数量的努力。为了指导基于科学的恢复工作并为未来监测这一边境种群提供基线，需要有关哪些资源和管理实践促进或限制该地区老虎出现的经验性定量信息。我们建立了一个大规模的野外相机捕捉网络，使用开放种群空间明确的捕获-再捕获模型来估计珲春自然保护区及周边地区的老虎密度、生存和招募情况。然后，我们拟合了一个考虑可检测性和空间自相关性的占用模型，以评估栖息地、主要猎物、干扰和管理对老虎栖息地使用模式的相对影响。我们的研究结果表明，大多数老虎的活动范围都靠近俄罗斯边境。研究区域内老虎的密度为 0.20 至 0.27 只/100 平方公里；珲春自然保护区的老虎密度是周边内陆林区的三倍。老虎的栖息地与大量放牧、人类住区和道路呈强烈负相关，与梅花鹿数量和植被覆盖呈正相关。这些发现有助于确定老虎数量减少和扩散限制的驱动因素，并完善在人类主导的跨境景观中老虎保护的策略。逐步减轻牛群和人类干扰对森林的影响，同时满足当地社区的经济需求，应该是增加老虎数量的关键优先行动。长期目标是通过改善大型有蹄类动物的栖息地来扩大老虎的分布。
Sporadic sightings of the endangered Amur tigerPanthera tigris altaicaalong the China-Russia border during the late 1990s sparked efforts to expand this subspecies distribution and abundance by restoring potentially suitable habitats in the Changbai Mountains. To guide science-based recovery efforts and provide a baseline for future monitoring of this border population, empirical, quantitative information is needed on what resources and management practices promote or limit the occurrence of tigers in the region. We established a large-scale field camera-trapping network to estimate tiger density, survival and recruitment in the Hunchun Nature Reserve and the surrounding area using an open population spatially explicit capture-recapture model. We then fitted an occupancy model that accounted for detectability and spatial autocorrelation to assess the relative influence of habitat, major prey, disturbance and management on tiger habitat use patterns. Our results show that the ranges of most tigers abut the border with Russia. Tiger densities ranged between 0.20 and 0.27 individuals/100 km2over the study area; in the Hunchun Nature Reserve, the tiger density was three times higher than that in the surrounding inland forested area. Tiger occupancy was strongly negatively related to heavy cattle grazing, human settlements and roads and was positively associated with sika deer abundance and vegetation cover. These findings can help to identify the drivers of tiger declines and dispersal limits and refine strategies for tiger conservation in the human-dominated transboundary landscape. Progressively alleviating the impacts of cattle and human disturbances on the forest, and simultaneously addressing the economic needs of local communities, should be key priority actions to increase tiger populations. The long-term goal is to expand tiger distribution by improving habitats for large ungulates.
