Population Dynamic of Far Eastern Leopard(Panthera pardus orientalis) in Wangqing Nature Reserve Based on Infrared Camera Monitoring

【Objective】 Far Eastern Leopard（Panthera pardus orientalis） disperses in the northernmost region and maintains the minimum population of Panthera pardus subspecies. It is evaluated as Critical Endangered in IUCN Red List. In this study, we analyzed long-term dynamic of population size and distribution of Far Eastern Leopard in Wangqing Nature Reserve and expected to provide scientific data for the protection of this endangered species. 【Method】 From Autumn 2013 to Autumn 2017, cameras were set up with a density of 1 pair per 3 km×3 km grid in the main leopard habitat in Wangqing Nature Reserve. The relative abundance indices（RAI） was used to calculate leopard abundance, the distribution area was defined by 99% kernel density contour, and individual was identified in Extract Compare software. The closure test, model selection and population estimation were performed for the data of effective monitoring period with CAPTURE software. The effective trapping area was estimated by projecting an 8 km radius buffer a
