| Habitat accessibility and snares impact large cats and their prey in Northeast Tiger and Leopard National Park, China | |
| 2024 Biological Conservation (289): 110414 | |
Snares have become a widespread hunting technique, with their indiscriminate nature jeopardizing terrestrial large carnivores. Since the lack of reliable data on snare distribution hampers an accurate evaluation of the potential risk. Continuous winter SMART (the Spatial Monitoring and Reporting Tool) patrols have operated in the Amur tiger (_Panthera tigris altaica_) and Amur leopard (_Panthera pardus orientalis_) ranges in northeast China from 2013 to 2020 to record wildlife occurrences and remove snares. Our research aimed to assess the snares threat pose in the Amur tiger range and whether snare removal benefited roe deer (_Capreolus pygargus_) and wild boar (_Sus scrofa_) recovery. We modeled the spatial distribution of Amur tigers, Amur leopards, and prey species, comparing their distributions before and after anti-poaching measures. We also assessed the overlap between Amur tigers, Amur leopards, and snare locations. Additionally, we used the MaxEnt model to predict snare distribution, and then we analyzed the overlap of snares with species at different periods between 2013 and 2015 and 2018-2020. Our results showed that the probability of occurrence of ungulates increased significantly around roads after snares were removed. Furthermore, we found that Amur tigers and Amur leopards distribution overlapped with snare locations suggesting that snares pose a serious risk to these non-target species. The overlap between snares and species has the same trend as the growing with species distribution, and the least significant increase is in DHZ-XNC. |
