Population viability analysis of Walia ibex (Capra walie) at Simien Mountains National Park ( SMNP ), Ethiopia

A population viability analysis (PVA) of the critically endangered Walia ibex (Capra walie) in Simien Mountains National Park, Ethiopia, reveals a low probability (0.15%) of the population reaching extinction thresholds under current conditions. The study estimates that, without environmental or demographic stochasticity and with effective habitat management, the species could persist for an average of 160 years before declining to a single individual. Researchers analyzed direct census data from 2009 alongside secondary sources, assessing growth parameters and long-term population stability. Findings underscore the importance of proactive conservation measures to mitigate threats from human activities and climate change, which could destabilize the species' habitat.
