Using camera traps and SECR models, it found mean densities of 2.74 individuals/100 km² in the Central range and 3.36 individuals/100 km² in the Western range, while the Eastern range showed very low activity. The study highlights a correlation between snow leopard density and the availability of blue sheep, noting that WCNP densities are low compared to similar regions in Nepal and India, likely due to high co-predator richness and limited prey. The authors recommend satellite telemetry to study habitat connectivity and community-based conservation to mitigate human-wildlife conflict.","ai_generated":true,"unit":"wwf-000773#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"The survey identified 9 adult snow leopards in the Central Park Range and 5 adults (plus 2 sub-adults) in the Western Park Range.
