Probability of cup plant occurrence depending on the significant parameters of the final model (Table 2) A habitat type (main groups). Abbreviations: IW = Inland waters, including riparian areas, OH = Open habitats, HS = Human settlement areas, WH = Woody habitats (shrubs, trees and forests) B distance to the field C age of the nearest cup plant field D portion of open soil. Parameters were fitted by the final model (Logistic regression, Table 2) with all other parameters held constant on median. The fitted probabilities of cup plant occurrence (blue line) and the 95%-confidence interval (grey band) are given. In addition, invaded plots (dashes in the top) and uninvaded plots (dashes in the bottom) are shown with a slight offset in case of multiple plots of one value. (n = 546).
