Qilianshan National Park, extends along the magnificent Qilian Mountains in north-eastern corner of the Tibetan Plateau. The mountains of 52,000 sq.km provide home and future refuges for snow leopard and many other wildlife. When the national park was established in 2016, an ambitious plan was announced to assess snow leopard populations across the entire mountain range. Since 2014, Dr. Yanlin Liu has been working with different teams on the snow leopard assessment in Qilian Mountains. Yanlin is currently the Science Director of the Chinese Felid Conservation Alliance and previously served as director of the snow leopard project for the ShanShui Conservation Center and a Post-Doc in the Chinese Academy of Forest. During this session he will share some of the opportunities and challenges his team is facing. He would love to hear form other SLN members and discuss large scale monitoring strategies.
