AbstractEvaluates the effects of elevation on the germination and distribution of annual species in a tidal freshwater marsh near Alexandria, Virginia. Growth of annual species increased with elevation and seeds germinated best in saturated rather than flooded conditions. Composition of the seed bank did not mirror that of vegetation. For example, Bidens laevis was frequently observed as seedlings and mature stems but was uncommon in the seed bank. Limitations to recruitment were found to be species specific.
