Abstract: 

Overexploitation by humans, such as hunting, is an important driver of global biodiversity loss. However, within-country overexploitation of wildlife is poorly understood, but is important for conservation policy. What is less known is the extent to which overexploitation affects the populations of wild species. In this talk, I will first introduce the assessment of the overview of illegal hunting of four vertebrate groups in China, using a court verdict database of over 9,200 convictions. I will then delve deeply into how the direct mortality impacts the populations of the declining migratory shorebirds in the East Asia-Australasia Flyway (EAAF). Our estimations of shorebird mortalities at stopover sites across China’s coasts during migratory seasons suggest that the combined effects of hunting, bycatch, and deterrence are overlooked threats to the decline of EAAF migratory shorebirds. Finally, I will discuss the knowledge gaps and potential ways to mitigate the impacts of overexploitation on wildlife in China, with a focus on mitigating shorebird mortalities across China's coasts.

摘要：

人类对野生动物的狩猎等过度捕捉方式是全球生物多样性丧失的一个重要驱动力。然而，我们对国家水平的野生动物过度利用了解较少，而国家水平评估对保护政策的推动十分重要。此外，过度利用多大程度会影响野外物种的种群的研究则更加缺少。在这次报告中，我首先将介绍基于9,200多条法律文书数据对中国陆生脊椎动物两栖、爬行、鸟类和兽类4个类群的狩猎进行的一次全面评估。其次，我将深入探讨人为造成的直接死亡对东亚-澳大利西亚种群下降严重的迁徙鸻鹬类种群的影响。我们在中国沿海鸻鹬停歇地估算的死亡量表明，狩猎、误捕和防鸟对这条迁飞区的鸻鹬种群造成了严重的威胁。最后，我将以降低中国沿海的鸻鹬类死亡量为重点，探讨缓解认为捕捉对野生动物影响的知识空缺和潜在途径。
