Abstract: The spread of invasive plant species is an increasing concern in many parts of the world. Negative effects on biodiversity, public health concerns, or economic damage are reported from the most vigorous of them. The monocarpic Heracleum mantegazzianum (Giant Hogweed, Apiaceae) is one of these species in Central Europe. The aim of the individual-based model (IBM) presented here was to assess the invasion status of H. mantegazzianum. This research was motivated by a recent study conducted by [Hüls, J., 2005. Populationsbiologische Untersuchung von Heracleum mantegazzianum Somm. & Lev. in Subpopulationen unterschiedlicher Individuendichte. Dissertation. Justus-Liebig-Universität Giessen, Germany (in German)], which predicted declines in a number of German Hogweed populations. This result contradicted many current, as well as past observations. In the presented study, we intend to resolve this controversy.
