Literature concerning Littorina irrorata is sparse, owing to the fact that its distribution is narrow in comparison to other members of the genus. The successful restoration of Littoraria irrorata productivity in rehabilitated salt marshes has received little attention, even though this consumer species has the potential to influence salt marsh production through both bottom-up and top-down pathways.
