面对热带地区日益严重的退化，认识到野生动物种群趋势的复杂性对于指导制定有效的保护和恢复战略至关重要。在这里，基于刚果民主共和国的一个案例研究，我们使用了一种民族动物学方法，并采用了一种协议，该协议捕获了关于诽谤的空间明确和时间生态知识。我们的案例研究证明了整个景观中大多数哺乳动物物种的总体枯竭概况，特别是红疣猴，羚羊和黑猩猩。大象已经在当地消失了，霍加皮和森林水牛只在北部地区存在。另一方面，杨甘壁自然保护区的可持续性表现为快速繁殖/小型物种的稳定种群。在我们的景观中，局部灭绝或哺乳动物数量急剧下降要么是冲突的直接后果，要么是源于1996年至2002年叛乱的级联效应的结果。从保护的角度来看，挑战在于了解如何在冲突后的背景下逆转消耗过程，并确定可以逆转级联效应以允许物种恢复的杠杆。我们鼓励在许多观察员经常使用的区域使用我们的方法。所提出的方法提供了成本效益高、可靠和空间明确的种群趋势数据，涵盖了广泛的物种，并使人们能够了解退化的历史模式以及发生变化的更广泛背景。
In the face of increased defaunation in tropical regions, embracing the complexity of wildlife population trends is important to guide the development of effective conservation and restoration strategies. Here, based on a case study in Democratic Republic of the Congo, we use an ethnozoological approach, with a protocol that captures spatially explicit and temporal ecological knowledge on defaunation. Our case study evidences the overall depletion profile for the majority of mammal species in the whole landscape and particularly for red colobus, orycterope, and chimpanzee. The elephant has already disappeared locally, and okapi and forest buffalo only persist in the northern part of the landscape. On the other hand, postdepletion sustainability seems to characterize Yangambi Reserve, with more stable populations of fast-reproducing/small-sized species. Local extinctions or sharp declines in mammal populations in our landscape are either the direct consequence of conflict or the result of cascading effects that have their origins in the rebellions between 1996 and 2002. From a conservation perspective, the challenge is to understand how the depletion process can be reversed in a postconflict context and to identify the levers that can inverse the cascading effect to allow species recovery. We encourage the use of our methodology in regions that are regularly used by a significant number of observers. The proposed methodology provides cost-effective, reliable, and spatially explicit data on population trends, covering for a wide range of species and allows to understand the historical pattern of defaunation as well the wider context in which changes occurred.
