1

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

2

What are the features at the high tide mark?

Low energy
Climax species = Sedge

3

Conditions at low tide mark:

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

4

What 2 main things do salt marshes need to form?

A low energy environment and a source of sediment

5

Examples of pioneer species:

Glasswort, Sea Purslane, Sedge

6
