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.
A salt marsh, saltmarsh or salting, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides.
Salt marshes are coastal wetlands that are flooded and drained by tides. They grow in marshy soils composed of deep mud and peat. Peat is made of decomposing plant matter in layers several feet thick.
Coastal salt marshes are dynamic intertidal ecosystems periodically flooded with saline or brackish water and dominated by halophytic grasses, herbs, and low shrubs. These ecosystems experience tidal regimes ranging from micro-tidal to macro-tidal and are widely distributed in middle and high latitudes worldwide, except Antarctica.
In the higher coastal intertidal zone between land and open saltwater or brackish water, a salt marsh is a distinctive coastal environment. The tides frequently flood these marshes, resulting in a habitat with peat and deep mud soil.
Salt marshes and coastal wetlands sequester and store carbon at a rate 10 times that of mature tropical forests, helping to moderate the effects of climate change. Also known as tidal wetlands, salt marshes are one part of a complex coastal ecosystem with interdependent habitats.
Salt marsh is home to many species, including the at-risk saltmarsh sparrow, which exists nowhere else. They nest only in the salt marshes of the Northeast, and their numbers are declining at an alarming rate as rising seas flood nests and drown chicks.
Salt marsh, area of low, flat, poorly drained ground that is subject to daily or occasional flooding by salt water or brackish water and is covered with a thick mat of grasses and plants such as sedges and rushes. Maritime salt marshes are variably subject to tidal action.
Atlantic Coast are collaborating to further restore and enhance salt marshes to protect the people, fsh and wildlife that depend on them, and to protect migration pathways for marsh as sea levels continue to rise.
Russia and the USA accounted for 64% of salt marsh losses, driven by hurricanes and coastal erosion. Our findings highlight the vulnerability of salt marsh systems to climatic changes such as SLR...
