Population trajectories and extinction probabilities for populations of large ungulates


September 2015 - December 2018


Understanding the importance of life history parameters is vital to managing wildlife populations. We will evaluate the minimum population size at which a populations are unlikely to go extinct and the population persistence times of various ungulate species across the Southwest in relation to variation in observed demographic rates. The intent is to generate population models using a suite of observed demographic parameters (and their variability), thereby assisting in management of multiple ungulate species across the southwestern United States.
