The diagram below was taken from a report by Han Olff et al published in the journal of ecology. It gives a good representation of the different biotic and abiotic factors that influence the vegetative succession.

Interspecific interactions between salt marsh plants in New England

# data[].attributes.body
This is a reasonably advanced paper discussing the interactions between different salt marsh plant species, and how these interactions cause distinct zoning in the succession of salt marshes. It also describes the effect of other biotic and abiotic factors on the succession of salt marshes in New England.
The main points to take from this article are that plant species in salt marshes each have different levels of dominance, and that if conditions are more favourable for the subordinant species, these will be able to out compete the 'dominant' species. The natural tides and solar radiation effect the salinity of salt marsh patches which leads to different species dominance.
Please read the highlighted parts to help get a brief understanding of this article.

Environment Agency Salt Marsh Importance

# data[].attributes.body
In this very lengthy report by the Environment Agency, there are some interesting points on; what a salt marsh is, the ecology of them, the importance of a salt marsh for the surrounding environment and the classification of salt marshes depending on their succession. There is also a section on human influences on salt marshes including salt marshes uses in coastal defences (linking into Coastal Systems and Landscapes).
Important sections to read have been highlighted.

Make sure you know what a salt marsh really is - here's a short explanation

# data[].attributes.attachment_link.readable_text
Salt marsh within Narragansett Bay National Estuarine Research Reserve. Salt marshes are coastal wetlands which are flooded and drained by tides.

Salt marshes are coastal wetlands that are flooded and drained by salt water brought in by the tides. They are marshy because the soil may be composed of deep mud and peat. Peat is made of decomposing plant matter that is often several feet thick. Peat is waterlogged, root-filled, and very spongy. Because salt marshes are frequently submerged by the tides and contain a lot of decomposing plant material, oxygen levels in the peat can be extremely low-a condition called hypoxia. Hypoxia is caused by the growth of bacteria which produce the sulfurous rotten-egg smell that is often associated with marshes and mud flats.

Salt marshes occur worldwide, particularly in middle to high latitudes. Thriving along protected shorelines, they are a common habitat in estuaries. In the U.S., salt marshes can be found on every coast. Approximately half of the nation's salt marshes are located along the Gulf Coast.

These intertidal habitats are essential for healthy fisheries, coastlines, and communities-and they are an integral part of our economy and culture. They also provide essential food, refuge, or nursery habitat for more than 75 percent of fisheries species, including shrimp, blue crab, and many finfish.

Salt marshes also protect shorelines from erosion by buffering wave action and trapping sediments. They reduce flooding by slowing and absorbing rainwater and protect water quality by filtering runoff, and by metabolizing excess nutrients.
