Research overview: camera-trap density estimation for snow leopards

Estimating snow leopard density relies heavily on camera trapping combined with capture-recapture, exploiting the unique rosette and spot patterns that allow individual identification. This overview surveys how researchers deploy camera arrays across steep, high-altitude terrain, often along ridgelines and cliff bases that snow leopards use for travel and scent-marking. Studies address the logistical extremes of fieldwork in remote mountains, the statistical challenges of low capture rates, and the integration of spatially explicit models to estimate density with quantified uncertainty. Genetic methods using scat have complemented camera trapping, particularly where photographic capture is too sparse. The overview emphasizes that reliable density estimates from sampled landscapes are the building blocks for any broader population assessment. It matters because, for a cat this elusive and sparsely distributed, methodological rigor at the site level is essential to producing credible conservation science.
