Though large felids are flagship species for wildlife conservation they are threatened due to various anthropogenic impacts. Mapping spatial patterns and quantification of threats to large felines can help conservation planning and resource allocation. The Leopard Panthera pardus, is categorized as Vulnerable by the IUCN as it faces a variety of threats. However, quantified data on the threats faced by leopards is scant. Hunting of wildlife using wire snares is one of the severest threats in India and elsewhere. Snaring, one of the simplest and most effective hunting techniques impacts other non-target species like the leopard. In this study, we document the spatial and temporal trends of snaring of leopards from India. Through content analysis of newspapers and news portals for the period January 2009-December 2020, we documented 113 incidents of leopards caught in snares of which 59.3% (5.5 leopards/year) resulted in mortality of leopards. Most snares (97.5%) were set to catch wild prey. Of the 84 incidents for which exact location details were available, the proportion of leopards caught in snares (54.7%, n = 46) and resulted in mortality (50%) in human-dense areas was significantly higher depicting an elevated threat from snares in these landscapes. Results from Generalised Additive Model indicated that snaring incidences increased with human population density. Percentage of protexted area to the geographical area within a district had little impact on the number of snaring incidents. The study results could help threat monitoring and conservation programs for leopards, especially outside the protexted area system.

量化钢丝圈套对印度卡纳塔克邦豹子的威胁

虽然大型猫科动物是野生动物保护的旗舰物种,但由于各种人为影响,它们受到威胁。绘制空间模式和量化对大型猫科动物的威胁有助于保护规划和资源分配。豹Panthera pardus, 被 IUCN 归类为易受攻击的,因为它面临各种威胁。然而,关于豹子面临的威胁的量化数据很少。使用铁丝网捕猎野生动物是印度和其他地方最严重的威胁之一。圈套是最简单、最有效的狩猎技术之一,它会影响其他非目标物种,例如豹子。在这项研究中,我们记录了捕获印度豹的空间和时间趋势。通过对 2009 年 1 月至 2020 年 12 月期间报纸和新闻门户网站的内容分析,我们记录了 113 起豹子陷入网罗的事件,其中 59.3%(5.5 只豹子/年)导致豹子死亡。大多数圈套 (97.5%) 都用于捕捉野生猎物。在可获得准确位置详细信息的 84 起事件中,被圈套捕获的豹子比例(54.7%,n = 46) 并导致人类密集地区的死亡率 (50%) 显着更高,这表明这些景观中陷阱的威胁加剧。广义加性模型的结果表明,圈套发生率随着人口密度的增加而增加。保护区面积与地理区域的百分比对圈套事件的数量几乎没有影响。研究结果可以帮助豹子的威胁监测和保护计划,尤其是在保护区系统之外。保护区面积与地理区域的百分比对圈套事件的数量几乎没有影响。研究结果可以帮助豹子的威胁监测和保护计划,尤其是在保护区系统之外。保护区面积与地理区域的百分比对圈套事件的数量几乎没有影响。研究结果可以帮助豹子的威胁监测和保护计划,尤其是在保护区系统之外。
