Resumo: | The optimal size and location of an invasive species population depend upon spatially differentiated biological growth, economic costs, and damages.  Although largely absent from most economic models, spatial considerations matter because the likelihood and magnitude of the invasion vary spatially and the threatened assets may be unevenly distributed across space.  We map the current and future populations of an invasive species, Miconia calvescens, on Oahu, Hawaii, and the potential damages to water quantity, quality, and endangered-species habitat, and weigh these against treatment costs.  We find that optimal densities vary from approximately 1% to 18% cover throughout the island.
