Vascular plant zonation and successional stages were studied in two brackish marshes of Calvert County, Maryland. One marsh is mature and stable, while the other is undergoing rapid succession from a former lake bottom. Soil depth, water salinity, and tidal heights were measured. Transect surveys show a general zonation of Spartina alterniflora→ Scripus olneyi→upland vegetation in the stable marsh, and a Spartina alterniflora→Scirpus robustus→ Typha angustifolia→upland vegetation succession in the developing marsh. Elevation of the marsh relative to mean high water is the most obvious factor influencing the plant distribution. [ABSTRACT FROM AUTHOR] |
