salt marshes

Alan Chamblin mrs.jensen 2nd pd


Salt marshes are coastal wetlands found throughout the world on shorelines and on the edges of where freshwater mixes with seawater. and that is where it makes the biotic factors hard to be there. temperature, photoperiod, soil salinity, and soil moisture confirm the hypothesis that abiotic factors differentially affect the germination of salt marsh plant

abiotic factors

SUBSTRATE: Brackish, often waterlogged, largely anaerobic, sandy sediment.

TOPOGRAPHY: Relatively flat, intertidal areas on, or sloping up slightly from, permanent water edge.

PROCESSES / DYNAMICS / ABIOTIC FACTORS: Rate of net primary production of organic matter among highest of any global ecosystem; aerial habitat above water dominated by marsh grasses and insect / spider / bird food webs.

Biotic factors

VEGETATION / ALGAE: Nonwoody, salt-tolerant plants; principal species are smooth cordgrass (on Atlantic side) and black needlerush; above mean high water level are numerous vascular plant species in addition to black needlerush; several hundred species of benthic microalgae and phytoplankton; a few species of large, multicellular seaweeds; occasional mangroves in warmer areas.

FAUNA: Abundant food and cover for resident and transient animals; nursery grounds for many fish and shellfish of commercial and recreational importance; many visiting birds and three exclusive residents—clapper rails, long-billed marsh wrens, and seaside sparrows; endangered Atlantic salt marsh snake.

Black needlerush: Juncus roemerianus

Blue crab: Callinectes sapidus

Cabbage Palm: Sabal palmetto

Christmas Berry: Lycium carolinianum

Clapper Rail: Rallus longirostris

Glasswort: Salicornia perennis

Horseshoe crab: Limulus polyphemus

Leather Fern: Acrostichum aureum

Osprey: Pandion haliaetus

Oyster: Crassostrea virginica

Raccoons: Procyon lotor

Seaside Sparrow: Ammodramus maritimus

Wax myrtle: Myrica cerifera
