Jan 12, 2009 salt marshes are found in estuarine areas with high (and fluctuating) salt content. thus, salt marsh plants must have adaptations for (http://www.eoearth.org/article/adaptations_of_marsh_plants)
Salt marsh plants are adapted to a harsh, semi-aquatic environment and saline soils. stout stems, small leaves, and physiological adaptations for salt (http://ceres.ca.gov/ceres/calweb/coastal/plants/smarsh.html)

The organisms that live in the salt marsh have special adaptations that allow them to and plants that can live successfully in the zone (see handouts). (http://mslc.rutgers.edu/nsfgk12/lessons%20and%20activities/lesson%20plans/life%2)
Salt tolerance involves physiological and biochemical adaptations for these include such well-known tidal saltmarsh plants as the cordgrasses (spartina (http://www.botgard.ucla.edu/html/botanytextbooks/lifeforms/halophytes/fulltexton)
Marsh grass, on the other hand, lets salts in but selectively excretes it--hence the salt crystals you find on their leaves. interestingly, wetland plants (http://kingfish.coastal.edu/biology/sgilman/778plants.htm)
Few plants have evolved adaptations to cope with the extreme conditions of salt marshes. plant zonation in a salt marsh results from species-specific (http://des.nh.gov/organization/commissioner/pip/factsheets/cp/documents/cp-06.pd)

These strategies may be adaptations for plant growth in the highly saline upper marsh zones. this indicates that salt marsh spartina and distichlis species (http://linkinghub.elsevier.com/retrieve/pii/s0098847207000299)
