The Snow Leopard Population Assessment in India (SPAI) was conducted by the Wildlife Institute of India (WII) under the Ministry of Environment, Forest and Climate Change (MoEF&CC), in collaboration with several state forest departments, the Nature Conservation Foundation, and WWF-India. The extensive fieldwork was carried out between 2019 and 2023, covering over 70% of the species’ potential habitat — about 120,000 square kilometres of the trans-Himalayan region.
