We wish to improve our understanding on the effect of plant patch on soil seed bank properties and, more specifically, how these seed reservoirs (seed bank patches) are affected by biotic (i.e. herbivory) and abiotic (i.e. climate) stressors and how they interact with the standing vegetation. Our results showed that although climate is the primary factor determining soil seed bank properties, its effect was profoundly modulated by grazing, as suggested by the existence of an important interaction between both stressors. Not only seed abundance and richness but also the relative dominance of total and persistent seed banks was affected by both environmental stressors.
