Invasive species are a prominent issue throughout the world due to their high economic and ecological impact on environments. The spongy moth, Lymantria dispar, is a well-known and intensely studied invasive species within the United States because of the high environmental (e.g., defoliation) and economic (e.g., management efforts) costs. Originally introduced in Massachusetts in 1869, their range now covers much of the Northeast and Midwest, with the potential to disperse much further. The goal of this study is to determine how the landscape has influenced L. dispar’s invasion rate through least-cost resistance modeling. Resistance modeling is a technique that combines the biology of L. dispar and landscape connectivity to potentially explain the invasion rate. Landscape connectivity has varying effects on invasion dynamics depending on the spatial scale. Monitoring efforts for L. dispar have occurred at a small spatial scale throughout the entire range for many years, which now provides the opportunity to look at invasion dynamics at small spatial scales. Identifying the landscape’s influence on invasion dynamics at these scales can assist in targeting management efforts to areas susceptible to invasion based on the landscape connectivity within the area.
