Back to Coastal and Oceanic Landforms
- A salt marsh known as;
- It is a coastal ecosystem in the upper coastal intertidal zone,between;
- Regularly flooded by the tides.
- It is dominated by salt-tolerant plants such as;
- These plants are terrestrial in origin.
- Salt marshes play a large role;
1.the aquatic food web.
2. the delivery of nutrients to coastal waters.
- They also support terrestrial animals and provide coastal protection.
- Salt marshes occur on low-energy shorelines in temperate and high-latitudes.
- Commonly shorelines consist of mud /sand flats.
- They are nourished with sediment from inflowing rivers & streams.
- These typically include sheltered environments such as;
- Salt marsh instead of herbaceous plants.
- Salt marshes are located among different landforms.
- Include deltaic marshes;
- Deltaic marshes associated with large rivers.
France (Rhone delta )
Spain (Ebro delta)
- They are extensive the rivers of the Mississippi Delta in the United States.
- In New Zealand, salt marshes occur head of estuaries
|Atlantic ribbed mussell, low marsh|
- Salt marshes are sometimes included in lagoons
example :Venetian Lagoon in Italy
- Plant species diversity is relatively low.
- The most common salt marsh plants are;
Glassworts (Salicornia spp.)
Cordgrass (Spartina spp.)
- Plants grow once the mud has been vegetated by the pioneer species.such as;
-sea lavenders (Limonium spp.)
-plantains (Plantago spp.)
- Salt marshes are quite photosynthetically active.
- They serve as depositories for a large amount of organic matter.
- Feeds a broad food chain of organisms from bacteria to mammals.
- Salt marshes are ecologically important providing habitats for native migratory fish and acting as sheltered feeding and nursery grounds.
- Restoring and managing salt marsh systems based on scientific principles.
- salt marshes are located next to urban areas.
