251! Estimating the Population of Snow Leopard in the Qinghai Area of Qilian Mountain National Park Using a Model

On October 22nd, the reporter learned from the press conference on snow leopard conservation achievements in the Qinghai area of Qilian Mountain National Park that since 2017, scientific research projects such as snow leopard population investigation, suitable habitat monitoring, satellite tracking, identification technology, and spatial distribution have been organized and implemented, achieving fruitful scientific research results.The survey and monitoring project of wild animals and plants such as snow leopards in Qilian Mountain National Park, initiated by the Chinese Academy of Forestry in 2017, identified 44 individual snow leopards through molecular biology methods and fecal sample analysis

On October 22nd, the reporter learned from the press conference on snow leopard conservation achievements in the Qinghai area of Qilian Mountain National Park that since 2017, scientific research projects such as snow leopard population investigation, suitable habitat monitoring, satellite tracking, identification technology, and spatial distribution have been organized and implemented, achieving fruitful scientific research results.

The survey and monitoring project of wild animals and plants such as snow leopards in Qilian Mountain National Park, initiated by the Chinese Academy of Forestry in 2017, identified 44 individual snow leopards through molecular biology methods and fecal sample analysis. In 2022, a special investigation was conducted on individual identification of snow leopards in the Qinghai area of Qilian Mountain National Park, including 63 in Qilian, 119 in Tianjun, and 24 in Menyuan. From 2021 to 2023, a snow leopard satellite tracking project was carried out, with a total of 5 individual snow leopards wearing satellite tracking collars.

Since March this year, by integrating survey data obtained from 2017 to 2022, the spatial marker recapture model (SCR) has been used to estimate the population and density of snow leopards in the Qinghai region, and a scientific report has been formed. The optimal model estimated the population of snow leopards in the Qinghai region to be 251 (95% confidence interval 171-369).

Snow leopard is the flagship and umbrella species of alpine ecosystems, and an indicator species for climate change and water resource security. The long-term existence and stable breeding of snow leopard populations vividly reflect the health of the ecosystem's functional quality, and their protection effectiveness directly affects the stability and integrity of the plateau mountain ecosystem.
