Where do salt marshes form?

The inter tidal zone (between high and low tide mark)
At low energy coastlines
Shelter from wind and waves
Flat land


What are the features at the high tide mark?

Low energy
Climax species = Sedge


Conditions at low tide mark:

Harsh conditions for life (high salinity -> salty)
Thin layer of nutrients from ground
Pioneer species = Glass wort


What 2 main things do salt marshes need to form?

A low energy environment and a source of sediment


Examples of pioneer species:

Glasswort, Sea Purslane, Sedge


What is plant succession?

The changing structure of a plant community over time initially bare sediment area is colonised by plants.
