Sammanfattning

Herbivory pressure on a forest stand and each plant individual may be affected by the spatial distribution of conspecific and allospecific plants on the site; whether the plants are standing in solitary or groupwise settings; or by the differences in the preference of plants in relation to each other. The study was conducted in southwest Sweden, where 120 plots (1508 m(2)) were visited and 1280 individual woody plants evaluated and measured. We tested the hypothesis that preferred woody plants can protect unpreferred conspecific and allospecific woody species against herbivory in a system with one dominant, generalist herbivore, the fallow deer (Dama L.), and that the effectiveness of this protection varies depending on the relative preference of the neighboring conspecific and allospecific woody species placed in conspecific groups or standing solitary. Our results support the hypothesis that preferred woody plants can protect unpreferred conspecific and allospecific woody species against herbivory in the case of Picea abies dominating stands.
