1. Parasitic plants affect the growth, reproduction and metabolism of their hosts and may also
influence the outcome of competitive interactions between host species and, consequently, the struc-
ture of entire host communities.
2. We investigate the effect of the root hemiparasitic plant Rhinanthus minor on plant community
dynamics using a spatial theoretical model. The model is parameterized with data from pairwise
interaction experiments under two nutrient levels between the hemiparasite and three grass species
