Invasive species can cause considerable economic and ecological damage. Mathematical models are essential in studying such an invasion process and suggesting management options. In this talk, I will present some recent techniques for analyzing the effects of spatial heterogeneity on spread rates of invasive species, in particular averaging techniques on different scales. I will apply these techniques to single species and competing species models. I will also discuss related rules of thumb for invasions with Allee effect. Finally, I will consider density-dependent dispersal processes and outline the mathematical challenges in analyzing the resulting models.
