Abstract

•A spatially-explicit stochastic model of wild pig population dynamics with social dynamics and spatio-temporal management strategies.•Zonation was the most effective and efficient spatial strategy regardless of landscape; better than targeting areas where density is highest.•Prioritizing culling during low-birthing period increased control effectiveness and efficiency, but effects were weaker than spatial culling.•Effects of temporal prioritization depended on spatial strategy and culling intensity.•Spatially-explicit model predicted lower culling intensity thresholds for population reduction than harvesting theory from logistic models.
