ABSTRACT Amidst the global biodiversity crisis, conserving endangered species like musk deer ( Moschus spp.) is crucial. China holds the highest musk deer diversity worldwide, with abundant populations, wide distribution, and significant musk production. We reviewed the morphology, population trends, distribution, conservation status, captive breeding, and related challenges of musk deer to inform targeted conservation strategies. Currently, wild musk deer populations are primarily distributed in western, central, and northeastern regions of China. Over the past seven decades, illegal hunting and habitat fragmentation have caused severe population declines, reducing most populations by over 97% since the 1950s. To alleviate pressure on wild populations and promote sustainable resource use, China initiated captive breeding of musk deer in 1958, resulting in a 5.6‐fold increase in captive musk deer from the 1990s to the 2020s. However, challenges like serious diseases hinder further expansion of artificial musk production. Given the limitations of both in situ and ex situ conservation, it is advised to establish or optimize natural reserves in musk deer habitat. Strengthening law enforcement, population monitoring, ecological research, captive breeding, reintroduction, and public awareness is essential for global musk deer conservation.
