​This four-year study, conducted from April 2013 to May 2017, provides a comprehensive inventory and update on the geographical distribution of wild carnivorous mammals in Western Algeria, with a specific focus on regionally endangered species. Spanning diverse biotopes, the primary objective was to establish a robust baseline assessment of the local carnivore population status.

​The investigative work employed a multi-source methodology, combining extensive direct and indirect observation (tracks, scat, and sightings) with surveys and questionnaires conducted among local communities, hunters, and forestry agents. This approach allowed for the collection of current ecological data alongside historical records across the study area.

​The research successfully documented 14 carnivorous mammal species across six families. Canids (Canis aureus, C. lupus, Vulpes rupellii, V. vulpes) were widely distributed. In contrast, Felids—including the regionally threatened Felis libyca, F. margarita, and F. caracal—were poorly represented. Mustelids (five species, including Lutra lutra) showed restricted distributions, and Hyaenidae (Hyaena hyaena) presence was minimal. Both the Viverrid (Genetta genetta) and Herpestidae (Herpestes ichneumon) were observed in low numbers, indicating a significant risk of extinction.

​These findings confirm the persistently endangered conservation status of these carnivore guilds, necessitating immediate intervention. The comprehensive data, including biological samples for genetic analysis, emphasizes the need for national and international cooperation to manage this valuable genetic material. This work also strongly complements the magnificent conservation efforts underway for the Saharan Cheetah (Acinonyx jubatus hecki), providing vital, up-to-date information for developing targeted protection strategies in Western Algeria.
