As a result salt marshes are constrained, by silt and saline water, to the type of communities it can sustain (Ranwell 1972). However because of the tidal nature of these ecosystems and the presence of many migratory birds we find some of the the most widley distributed plant species in the world (Ranwell 1972). The habitat is typically high in phosphates but low in nitrogen. Sulphur washed in from the sea collects in the soil and during dry periods lowers the soil pH (Chapman & Reiss 2000)....(short extract)
