Do salt marshes have vegetation?

It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments.

Salt Marshes suit many species. The marsh is crawling with hundreds of kinds of invertebrates. Fiddler crabs, hermit crabs and stone crabs join snails, mussels and worms in finding food and shelter in the salt marsh. Fish and shrimp come into salt marshes looking for food or for a place to lay their eggs.

What kinds of resources can humans extract from salt marshes?

Found from arctic to subtropical climates, salt marshes export carbon and energy into the water column, store carbon in their root systems and sediments, and filter nutrients, pollutants and pathogens from water along global coastlines. Salt marshes also help to protect against storm damage, flooding and erosion.

Are salt marshes turbid?

Almost 70 % of the area is overgrown by salt marsh vegetation. The remaining 30 % consists of mud flats, sandbanks and a network of channels. Each tide, the brackish water overflows a large part of the area.

What makes salt marshes unique?

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. Hypoxia is caused by the growth of bacteria which produce the sulfurous rotten-egg smell that is often associated with marshes and mud flats.

Can salt marshes sustain life?

They provide shelter, food and nursery grounds for more than 75% of coastal fisheries species including shrimp, crab and many finfish.

Are salt marshes in danger?

Salt marshes inhabit low-energy, intertidal shorelines worldwide and are among the most abundant and productive coastal ecosystems. Currently, the major threats to salt-marsh resources include climate-change effects, pollution, land use change, and invasive species.
