In wood pastures spatial associations of tree saplings with nurse structures such as unpalatable plants are generally explained as associational resistance; i.e. reduced herbivory by association with a defended neighbour. However, these associations may result from other underlying processes that occur at the seed stage. Here we tested whether the observed associations between...

Question: Are tree saplings in wooded pastures spatially associated with specific nurse structures or plants that facili-tate tree sapling survival? Location: Wooded pastures in the Jura Mountains, Switzer-land. Methods: In two sites, 73 km apart, we sampled 294 plots of4 m², systematically distributed on 1 ha. We recorded number and height of all established Picea abies...

1. In endangered wooded pasture ecosystems established tree saplings are frequently found in spatial association with protective structures, suggesting nurse effects. This associational resistance is thought to be a driving force behind tree regeneration in wooded pastures. Experimental evidence for associational resistance is, however, scarce. We studied the effects of unpalatable plants on tree...
