Population Viability Analysis of the Endangered Roan Antelope in Ruma National Park, Kenya, and Implications for Management

Figure 3

The impact of age-specific mortalities and catastrophes on roan population viability. The mean population size at 30 years was obtained by simulating a PVA model over a 30-year period with an initial population of 43 roans under varying levels of age-specific moralities and catastrophes from 0% to 40%.
