Seasonal patterns of aboveground plant mass and the depth distribution of live roots, rhizomes, and dead belowground organic matter were measured for Spartina alterniflora and Spartina cynosuroides in Georgia tidal marshes. Peak live aboveground biomass was 1.6x higher for S. cynosuroides than for S. alterniflora. Live biomass was 2.4x more belowground than aboveground for S. cynosuroides and 1.7x for S. alterniflora. Rhizomes made up 76 and 87% of live belowground biomass during the year. Mirrored patterns of biomass accumulation and loss in above- and belowground tissues during the year suggest the importance of seasonal storage and redistribution of organic matter.
