Costs and decisions in population models

Phil Pollett and Joshua Ross

Abstract: Many populations have a negative impact on their habitat, or upon other species in the environment, if their numbers become too large. We examine two control regimes designed to maintain the population close to a given threshold, and we present models that allow us to study the effects of each regime on population viability. We will present a general method for estimating the total cost of controlling the population over its life time and use this to compare control methods. The optimal choice of control parameters will also be discussed.
