The Barbary sheep (Ammotragus lervia) is a hoofed animal ranked globally as a vulnerable species. The Tlemcen hunting reserve is one of the structures that aims to protect, preserve and develop this species in ex-situ, but the problem is that the reserve does not have the history of its provenance; On the basis of this observation, we have highlighted our study, which is divided into two parts. The first part focus on a morphometric  study targeting 42 adult individuals, 18 of which were imported from the United Arab Emirates and 24  developed in Algeria; this study focused on 18 variables including 15 quantitative and 3 qualitative. The data collected were subjected to a statistical analysis by the software R which; the principal component analysis (PCA) and the ascending hierarchical classification that the two populations are distinct from each other without significant separation since the work has was conducted on the same species. In addition, we have been able to identify specific subjects of each population that can be used as breeders. As for the second part, it is a phylogenetic study targeting the population of Algeria only, in which a molecular analysis of  6 collected samples has allowed us to obtain a partial DNA sequence of cytochrome b. We subsequently retrieved the nucleotide sequences of cytochrome b from the same taxonomy from the GenBank database and processed all the sequences by the MEGA software, after alignment by the ClustalW method. The phylogenetic tree showed that the barbary sheep population of the Tlemcen hunting reserve is a North African subspecies
