Illegal harvesting and trading of wildlife have become major threats to global biodiversity and public health. Although China is widely recognized as an important destination for wildlife illegally obtained abroad, little attention has been given to illegal hunting within its borders. Here we extracted 9,256 convictions for illegal hunting from a nationwide database of trial verdicts in China spanning January 2014 to March 2020. These convictions involved illegal hunting of 21% (n = 673) of China's amphibian, reptile, bird and mammal species, including 25% of imperilled species in these groups. Sample-based extrapolation indicates that many more species were taken illegally during this period. Larger body mass and range size (for all groups), and proximity to urban markets (for amphibians and birds) increase the probability of a species appearing in the convictions database. Convictions pertained overwhelmingly to illegal hunting for commercial purposes and involved all major habitats across China. A small number of convictions represented most of the animals taken, indicating the existence of large commercial poaching operations. Prefectures closer to urban markets show higher densities of convictions and more individual animals taken. Our results suggest that illegal hunting is a major, overlooked threat to biodiversity throughout China.
非法采集和交易野生动植物已成为全球生物多样性和公共卫生的主要威胁。尽管中国被广泛认为是非法从国外获取的野生动植物的重要目的地,但对其境内非法狩猎的关注甚少。在这里,我们从中国 2014 年 1 月至 2020 年 3 月期间全国性的审判判决数据库中提取了 9256 项非法狩猎的定罪。这些定罪涉及中国 21%(n=673)的两栖动物、爬行动物、鸟类和哺乳动物物种的非法狩猎,其中包括这些群体中濒危物种的 25%。基于样本的推断表明,在此期间有更多的物种被非法猎捕。更大的体重和分布范围(所有群体)以及靠近城市市场(两栖动物和鸟类)增加了物种出现在定罪数据库中的可能性。定罪绝大多数是为商业目的非法狩猎,并涉及中国各地的主要栖息地。少数定罪代表了大部分被捕动物,表明存在大规模的商业偷猎活动。靠近城市市场的地区显示出更高的定罪密度和更多被捕获的个体动物。我们的研究结果表明,非法狩猎是中国各地生物多样性面临的一个主要而被忽视的威胁。
