It is important that native plants are able to successfully emerge in wetlands because they play an important role in maintaining diversity. The relationship between seed buoyancy and seedling emergence was analyzed for three wetland species of the same genus: Elymus canadensis (FACU), Elymus macgregorii (FACW), and Elymus virginicus (FACW). E. macgregorii seemed to be the most buoyant, and E. virginicus and E. canadensis demonstrated very similar, less buoyant levels. Based on the idea that more buoyant seeds will be deposited at a shallow depth, and less buoyant seeds will be deposited at a deeper soil level, a relationship between depth of the artificially placed seed and the ability to emerge was evident in the FACW species. E. macgregorii was less buoyant (with respect to the other two species) and more successful in emerging from a shallow depth. E. virginicus was more buoyant and more successful in emerging from a deep soil level. This relationship was not observed in the FACU species. E. canadensis was more buoyant and more successful in emerging from a shallow depth.
