Population Simulation for Red Fox Management in Kentucky

A stochastic computer model was written to simulate the dynamics of red fox (Vulpes vulpes) populations in Kentucky. The model consists of the main module equations and 2 submodules: ASMOSU and BIRTH. Main module equations calculate the number and density of individuals in each age class and the total population. ASMOSU calculates all total and age specific mortality rates. BIRTH calculates the number of individuals recruited into the 0.5-year age class. The model is useful for evaluating scenarios for red fox management in Kentucky because, except for minor exceptions, it validly simulates changes in red fox population dynamics. The model is most sensitive to perturbations in the input values of fecundity, the area inhabited by the population, and the parasitism mortality rate.
