13 December 2021If individuals have spatially dierentiated preferences for sites or areas impacted by an invasive alien species, eective management must take this heterogeneity into account and target sites or areas accordingly. In this paper, we estimate spatially dierentiated preferences for the management of primrose willow (Ludwigia grandiora), an invasive weed spreading in a French regional park. We use an original spatially explicit discrete choice experiment to evaluate individuals’ willingness to pay (WTP) to control the invasion in dierent areas of the regional park. Our results indicate that WTP for management highly depends on the area considered, with areas where it is three times higher than others. We analyze the main factors explaining the heterogeneity of preferences and show that the closer respondents live to the park, the more they visit and/or practice activities in it, the higher their WTP and spatial preferences. Park residents and regular users have highWTP and unambiguous preferences for targeting control to specic areas. Non-residents and occasional users have much lower WTP and more homogeneous spatial preferences. These results suggest that implementing management strategies that spatially target invasion control according to public preferences is likely to produce signicant utility gains. These gains are all the more important as the preferences taken into account are those of the stakeholders directly concerned by the invasion, the residents and regular park users. Ignoring these spatial preferences will lead to sub-optimal invasion management.
