註釋In this study we mapped (alien) invasive shrubs for management and conservation purposes. On the study site, the Wadden Sea Island of Vlieland, they are a serious treat for the quality of the grey dune habitat. We developed a remote sensing approach that delivers detailed and standardized maps of (alien) shrub cover. Three classification methods are used: maximum likelihood (ML) classification of aerial photographs, maximum likelihood classification aerial photographs combined with vegetation heights derived from LIDAR data (ML+), and object-based shrub classification.
