Walia ibex are very agile and hardy, able to climb on bare rock and survive on sparse vegetation. Population viability analysis (PVA) has been applied to the management of many threatened populations. Several of the preferred diet items of the Walia ibex (Alchemilla sp., Hypericum revolutum, Erica arborea and Rumex sp.) The popula/on size of Walia ibex has drama/cally declined and it is included in the IUCN Red-‐list as a cri/cally endangered species since 1996. The adult walia ibex's only known wild predator is the hyena. They have thick fur on their bodies and they can exist on a more limited diet. They are listed as vulnerable by IUCN. These results indicate that there is potential for competition between the two species, especially during the dry season, when resources are limited. As a result, the geographical isolation of Walia ibex and Nubian ibex leads them to develop adaptations in response to ecological requirements within their respective geographical distribution ranges (Nievergelt, 1981; Gebremedhin et al., 2009). Walia ibex are most active in the morning and evening, and will rest in the sun on rock ledges. The correlation between the two repeated counts was .
