Salt Marsh

Marine and Coastal Biomes

A salt marsh is a coastal wetland biome of low-lying land regularly flooded and drained by the tides, dominated by salt-tolerant grasses, rushes and low shrubs able to grow rooted in waterlogged, saline soil rather than the trees found in a freshwater swamp or a tropical mangrove forest. Common in temperate latitudes where mangroves cannot survive winter cold, salt marshes trap sediment, buffer inland areas from storm surge and serve as a nursery ground for many coastal fish and shellfish species, much as mangrove forests do in warmer latitudes. They are counted among the most productive biomes on Earth per unit area, though extensive historical drainage for agriculture and coastal development has left many salt marsh systems reduced from their original extent.

Annual Precipitation (mm)
452 1
452mm (17.8 inches) is this same reserve's 1967-1979 average, which itself ranged from about 199mm to 932mm year to year; salt marshes on wetter coasts receive far more.
Typical Low Temperature (C)
4 1
The source states only that the coldest month's average minimum stays above freezing, without an exact figure; 4C is a reasoned representative value for that same southern California site, not a measured global low.
Typical High Temperature (C)
23.9 1
23.9C (75F) is the average August maximum at a single well-documented site, the Carpinteria Salt Marsh Reserve in coastal southern California, not a global figure; salt marshes occur from subtropical to subarctic coasts.

Although an aquatic predator, C. sapidus will remain in shallow pits in salt marshes at low tide and ambush intertidal prey such as fiddler crabs (e.g., Minuca pugnax) and purple marsh crabs (Sesarma reticulatum) C. sapidus may be able to control populations of the invasive green crab, Carcinus maenas; numbers of the two species are negatively correlated, and C. maenas is not f

The breeding habitats are most commonly alkali lake shores, wetlands, salt marshes, and coastland, which is fitting with the results of a study that investigated what makes an environment suitable for a breeding habitat for the Kentish plover.
