Estimating snow leopard and prey populations at large spatial scales

open access: yesEcological Solutions and Evidence, Volume 2, Issue 4, October–December 2021., 2021
Estimating populations at large spatial scales can be challenging because of biases associated with limited sampling. We demonstrate a two‐step approach to estimate snow leopard and their prey populations that uses occupancy surveys to inform camera‐trapping survey design.
