Saltwater marshes are found around the world in mid to high [[latitude]]s, wherever there are sections of protected coastline. They are located close enough to the shoreline that the motion of the [[tide]]s affects them, and, sporadically, they are covered with water. They flourish where the rate of sediment buildup is greater than the rate at which the land level is sinking.<ref name="Rafferty" /> Salt marshes are dominated by specially adapted rooted vegetation, primarily salt-tolerant grasses.<ref name="ReferenceA">Keddy, P.A. 2010.

Salt marshes are most commonly found in [[lagoon]]s, [[estuaries]], and on the sheltered side of a shingle or [[Sandspit (landform)|sandspit]]. The currents there carry the fine particles around to the quiet side of the spit, and sediment begins to build up. These locations allow the marshes to absorb the excess nutrients from the water running through them before they reach the oceans and estuaries.<ref name="Rafferty" /> These marshes are slowly declining. Coastal development and [[urban sprawl]] have caused significant loss of these essential habitats.<ref>B.R. Silliman, E.D. Grosholz, and M.D. Bertness (eds.) 2009. Human Impacts on Salt Marshes.
