There are many ways in which large carnivores and humans interact in shared spaces. In this study we provide insights into human-leopard relationships in an entirely modified, human-dominated landscape inhabited by dense populations of humans (266 per km), their livestock (162 per km) and relatively high densities of large predators (10 per 100 km). No human deaths were recorded, and livestock losses to leopards numbered only 0.45 per kmper year (averaged over three years) despite the almost complete dependency of leopards on domestic animals as prey. Predation was not the major cause of livestock mortality as diseases and natural causes caused higher losses (80% of self-reported losses). We also found that ineffective night time livestock protection and the presence of domestic dogs increased the probability of a farmer facing leopard attacks on livestock. Resident farmers faced much lower livestock losses to leopard predation in contrast to the migratory shepherds who reported much higher losses, but rarely availed of the government compensation schemes. We recommend that local wildlife managers continue to shift from reactive measures such as leopard captures after livestock attacks to proactive measures such as focusing on effective livestock protection and informing the affected communities about safety measures to be taken where leopards occur in rural landscapes. The natural causes of livestock deaths due do diseases may be better prevented by involving animal husbandry department for timely vaccinations and treatment.
大型食肉动物与人类在共享空间中有多种互动方式。在本研究中,我们深入探讨了在一个完全被改造、以人类为主导的景观中,人类与豹的关系。该景观中居住着密集的人口(每平方公里266人)、他们的牲畜(每平方公里162头)以及相对较高密度的大型食肉动物(每100平方公里10只)。没有记录到人类死亡,尽管豹几乎完全依赖家畜作为猎物,但豹对家畜的捕杀损失仅为每年每平方公里0.45头(三年平均)。捕食并非家畜死亡的主要原因,因为疾病和自然原因造成的损失更高(自我报告损失的80%)。我们还发现,夜间家畜保护措施不力以及家犬的存在增加了农民面临豹袭击家畜的可能性。与迁徙牧民相比,当地农民因豹捕食造成的家畜损失要低得多,迁徙牧民报告的损失要高得多,但很少利用政府的补偿计划。我们建议,当地野生动物管理人员应继续从家畜被袭击后捕捉豹等被动措施,转向主动措施,如专注于有效的家畜保护,并告知受影响社区在农村景观中有豹出没的地方应采取的安全措施。通过让畜牧部门及时进行疫苗接种和治疗,可能更好地预防因疾病导致家畜死亡的自然原因。
