Status and social structure of the critically endangered dama gazelle (Nanger dama) in the Aïr & Ténéré National Nature Reserve, Niger

A critically endangered dama gazelle population in Niger's Aïr & Ténéré National Nature Reserve shows signs of stability but faces severe recruitment challenges. The study, spanning 2017–2023, reveals a phenotypically mixed population with limited juvenile presence, indicating low reproductive success. Using direct observations, indirect signs, and camera traps, researchers documented an increasing trend in indirect evidence and a stable capture rate (CTR: 1.59 events per 100 trap-days). Most individuals were solitary adults, with group sizes averaging 2–4, while calving occurred in two distinct seasons. Phenotypic diversity suggests a spectrum rather than distinct subspecies, but the low proportion of young individuals (<20%) underscores urgent conservation needs, including habitat protection and reduced disturbance.
