We assessed population status of large predators and their prey in the Udanti Sitanadi Tiger Reserve (USTR), an almost unexplored Protected Area (PA) in Chhattisgarh State, Central India. Our total effort of 976 km walked on 108 spatially replicated line transects yielded low densities for wild ungulates (8.46 ± 2.1 SE individuals/km 2 ) compared to other PAs in this region. Camera trap surveys with total effort of 3004 trap nights generated 37 photo-captures of only two individual tigers, while population and densities for leopards (22.03 ± 0.19 SE individuals and 1.56 ± 0.36 SE/100 km 2 ) and striped hyenas (18.18 ± 0.45 SE individuals and 1.69 ± 0.43 SE/100 km 2 ), were quite low too. Predators and prey in USTR demonstrated temporal avoidance of human presence, which could be linked to anthropogenic intrusions across the reserve. Therefore, simultaneous implementations of alternate livelihood-based strategies and voluntary village rehabilitations along with efficient legal enforcements are urgently needed to mitigate such a critical conservation crisis in USTR. 我们评估了印度中部恰蒂斯加尔邦一处几乎未被开发的乌丹蒂-西塔那迪老虎保护区（USTR）内的大型捕食者及其猎物的种群状况。我们完成了108条空间重复样线的调查，共计976 km，发现该地区的野生有蹄类动物密度（8.46 ± 2.1只/km 2 ）低于该区域其他保护区的有蹄类密度水平。基于自动相机调查的 3004个持续拍摄日，仅拍摄到2只老虎个体的37张照片。此外，豹（22.03 ± 0.19只，密度1.56 ± 0.36只/100 km 2 ）和斑纹鬣狗（18.18 ± 0.45只，密度1.69 ± 0.43只/100 km 2 ）的种群数量和密度也较低。研究还发现，在USTR 内，捕食者和猎物在时间维度上对人类出现的回避，这可能与遍布整个保护区的人为干扰有关。因此，为了缓解USTR内迫切的保护危机，需要同步实施有效执法下的替代生计策略和自愿性村庄重建。 For wildlife researchers—Science-based wildlife population assessments are necessary across all the Protected Areas and beyond. For Wildlife Managers and frontline staff—more intensive patrolling and monitoring efforts are needed for reducing human-wildlife conflicts. For conservation practitioners—alternate livelihood-based initiatives would be beneficial to raise the financial standard of living for the communities in and around USTR and reduction of their dependencies on natural resources.
