Research overview: the Saharan and Northwest African cheetah

A small, cryptic population of cheetahs survives across the Sahara and Sahel of Northwest Africa, representing a distinct and critically endangered lineage adapted to extreme desert conditions. This overview surveys the sparse research on these animals, which range over enormous areas at very low density and are exceptionally difficult to study. Camera-trap and genetic surveys have confirmed their persistence in parts of Algeria, Niger, and neighboring countries, while documenting their rarity and the threats of prey depletion, persecution, and habitat degradation. Researchers describe behavioral and physiological adaptations to desert life, including possible nocturnal activity and water independence. The overview frames the Saharan cheetah as one of the least-known and most imperiled big cat populations on Earth, where even basic information on numbers and distribution remains a conservation priority.
