Salt marsh during low tide, mean low tide, high tide and very high tide (spring tide). A coastal salt marsh in Perry, Florida, USA.. 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.
Few terrestrial animals inhabit the coastal salt marsh. One endangered mammal is the salt marsh harvest mouse (Reithrodontomys raviventris) which occurs in the San Francisco Bay region. Likewise, only five species of birds are resident in this habitat and four are considered rare or endangered.
While this species is a key member of the salt marsh flora in its native habitat, it is known as a harmful invasive species in other parts of the world. It is a notorious pest in the San Francisco Bay Area, where it out-competes native plants such as soft bird's beak and alters the habitat of rare animals such as Ridgway's rail. [5]
Salt marshes can be generally divided into the high marsh, low marsh, and the upland border. The low marsh is closer to the ocean, with it being flooded at nearly every tide except low tide. [53] The high marsh is located between the low marsh and the upland border and it usually only flooded when higher than usual tides are present. [53]

It grows out into the water at the seaward edge of a salt marsh, and accumulates sediment and enables other habitat-engineering species, such as mussels, to settle. This accumulation of sediment and other substrate-building species gradually builds up the level of the land at the seaward edge, and other, higher-marsh species move onto the new land.
White water lilies are a typical marsh plant in European areas of deeper water. Many kinds of birds nest in marshes; this one is a yellow-headed blackbird.. Marshes provide a habitat for many species of plants, animals, and insects that have adapted to living in flooded conditions or other environments. [1]
