Succession
Plant:
Long term change to the plant community in the area. Marram grass is a pioneer plant which grows and dies, releasing nutrients and encouraging other species to grow.
Salt Marsh:
Algal stage
Pioneer stage
Established stage
Stabilisation
Climax vegetation
Waves & Sea Levels
Coastline Energy
High-energy:
Destructive waves
Rocky landforms
High rates of erosion
Low-energy:
Constructive waves
Sandy areas
High rates of deposition
Sea Level Change
Isostatic:
Localised
Land subsides and rebounds
Could be due to post-glacial adjustment
Eustatic:
Globalised
Due to thermal expansion
Cause by global warming
