Abstract: As one of the most critically endangered mammals in Europe, the European mink (Mustela lutreola) is in need of urgent conservation actions to ensure its survival. With the disappearance of the American mink (Neogale vison) in the Netherlands, one of the European mink’s primary threats has been eliminated here, creating an opportunity for its reintroduction. The aim of this study was to identify the potentially most suitable areas for a reintroduction in the Netherlands. To this end, a rule-based habitat suitability model was created based on land use, natural waterways, road density and human presence. The Netherlands seems to have a considerable number of suitable areas for reintroduction, although their favourability varies depending on factors such as fragmentation and muskrat (Ondatra zibethicus) control efforts. Wetland areas in the north of the Netherlands were generally identified as the most suitable for a reintroduction, with the Weerribben-Wieden and wetlands at the border of the provinces of Groningen and Drenthe as standout areas. Lowland peat areas in the west with high densities of American crayfish (Procambarus clarkii and Procambarus acutus) are also good options, although fragmentation and the high intensity of muskrat trapping present notable challenges here. Further investigation into the potential release sites is recommended to examine habitat characteristics in greater detail, assess connectivity and get a grip on the local political and societal dynamics that will play an important role in the success of a reintroduction.
