Wollheim. Marker horizons consist of a mineral such as feldspar that is buried at a known depth within wetland substrates to record the increase in overlying substrate over long time periods. The flora of a salt marsh is differentiated into levels according to the plants' individual tolerance of salinity and water table levels. Such marsh landforms include deltaic marshes, estuarine, back-barrier, open coast, embayments and drowned-valley marshes. Tyrell, and M. Congretel.

Establishing a physical and biological basis for salt marsh restoration and management in the Avon-Heathcote Estuary. 2002. Salt marshes are ecologically important providing habitats for native migratory fish and acting as sheltered feeding and nursery grounds. Estuaries are partly sheltered areas found near river mouths where freshwater mixes with seawater. Boorman, L., Hazelden, J., and Boorman, M. (2002). (cordgrass) that has been attributed to herbivory by the crab Sesarma reticulatum. This allows a more direct diffusion path for the export of nitrogen (in the form of gaseous nitrogen (N2)) into the flushing tidal water. [5] They are highly productive ecosystems, and when net productivity is measured in g m−2 yr−1 they are equalled only by tropical rainforests. With elevated sea levels, salt marsh vegetation would likely be more exposed to more frequent inundation rates and they must be adaptable or tolerant of the consequential increased salinity levels and anaerobic conditions. Vegetation found at the water must be able to survive high salt concentrations, periodical submersion, and a certain amount of water movement, while plants further inland in the marsh can sometimes experience dry, low-nutrient conditions. However, these plants do not grow together in the same area. [28], Cultivation of land upstream from the salt marsh can introduce increased silt inputs and raise the rate of primary sediment accretion on the tidal flats, so that pioneer species can spread further onto the flats and grow rapidly upwards out of the level of tidal inundation. The killifish is a mosquito predator, so the loss of habitat actually led to higher mosquito populations, and adversely affected wading birds that preyed on the killifish. "Trapping effect of tidal marsh vegetation on suspended sediment, Yangtze Delta". These types of restoration projects are often unsuccessful as vegetation tends to struggle to revert to its original structure and the natural tidal cycles are shifted due to land changes. With the impacts of this habitat and its importance now realised, a growing interest in restoring salt marshes, through managed retreat or the reclamation of land has been established. Salt marshes in Rhode Island are already showing evidence of being overwhelmed by rising sea levels. The New England salt marsh is subject to strong tidal influences and shows distinct patterns of zonation. Marine Geology. The mean sea level changes seasonally due to the warming and cooling of the ocean throughout the year. The water in salt marshes varies from completely saturated with salt to freshwater.

Deltaic marshes are associated with large rivers where many occur in Southern Europe such as the Camargue, France in the Rhône delta or the Ebro delta in Spain. Many birds use salt marshes for feeding, such as American oystercatchers, egrets, herons and sandpipers. Kirwan, M. L., Murray, A.

The salt marshes in the state of Connecticut in the United States have long been an area lost to fill and dredging.
