Protected areas are extremely important for the long term viability of biodiversity in a densely populated country like India where land is a scarce resource. However, protected areas cover only 5% of the land area in India and in the case of large carnivores that range widely, human use landscapes will function as important habitats required for gene flow to occur between protected areas. In this study, we used photographic capture recapture analysis to assess the density of large carnivores in a human-dominated agricultural landscape with density >300 people/km(2) in western Maharashtra, India. We found evidence of a wide suite of wild carnivores inhabiting a cropland landscape devoid of wilderness and wild herbivore prey. Furthermore, the large carnivores; leopard (Panthera pardus) and striped hyaena (Hyaena hyaena) occurred at relatively high density of 4.8±1.2 (sd) adults/100 km(2) and 5.03±1.3 (sd) adults/100 km(2) respectively. This situation has never been reported before where 10 large carnivores/100 km(2) are sharing space with dense human populations in a completely modified landscape. Human attacks by leopards were rare despite a potentially volatile situation considering that the leopard has been involved in serious conflict, including human deaths in adjoining areas. The results of our work push the frontiers of our understanding of the adaptability of both, humans and wildlife to each other's presence. The results also highlight the urgent need to shift from a PA centric to a landscape level conservation approach, where issues are more complex, and the potential for conflict is also very high. It also highlights the need for a serious rethink of conservation policy, law and practice where the current management focus is restricted to wildlife inside Protected Areas.
保护区对于像印度这样人口密集、土地资源稀缺的国家的生物多样性的长期生存能力至关重要。然而,保护区仅覆盖印度土地面积的 5%,对于那些广泛分布的大型食肉动物而言,人类使用的景观将成为在保护区之间发生基因流动所必需的重要栖息地。在本研究中,我们使用相片捕获再捕获分析来评估印度马哈拉施特拉邦西部一个以农业为主、人口密度超过 300 人/平方公里的人类主导景观中的大型食肉动物密度。我们发现有广泛的野生食肉动物栖息在没有荒野和野生食草动物猎物的农田景观中。此外,大型食肉动物——豹( Panthera pardus )和条纹鬣狗( Hyaena hyaena )的密度分别为 4.8±1.2(标准差)只/100 平方公里和 5.03±1.3(标准差)只/100 平方公里,相对较高。这种情况以前从未报道过,在一个完全被改造的景观中,有 10 只大型食肉动物/100 平方公里与密集的人类种群共享空间。尽管考虑到豹已卷入邻近地区的严重冲突,包括人类死亡事件,情况可能不稳定,但豹对人类的攻击却很少见。我们的工作结果推动了我们对人类和野生动物彼此适应能力的理解的前沿。结果还强调迫切需要从以保护区为中心的保护方法转变为景观水平的保护方法,因为在这种方法中,问题更加复杂,冲突的可能性也非常高。它还强调需要对保护政策、法律和实践进行认真反思,当前的管理重点仅限于保护区内的野生动物。
