Robustness curves using the spatial dispersal model. \(\tilde{K}_{L}\) is the estimated population threshold for detection, assumed to be the same at each location \(L = 1, \ldots ,6\) and \(\tilde{E}n\) is the estimated annual number of entries of Asian house gecko after border inspection to any of the locations on Barrow Island. The corresponding optimal surveillance cost in each situation are listed as ‘SurvExpe’ in the legend. The lines with the same value of \(\tilde{E}n\) are aligned with each other.
