Primary Succession on the Sefton Coast
 

Coastal sand dunes provide an excellent environment for the study of primary succession. The vegetated dunes within the system have developed on a substrate of unconsolidated sand.

 

This sand has been picked up by the wind from the wide sandy foreshore at low tide and deposited at the top of the beach around any obstacle which interrupts the flow of the wind and reduces its energy - it may be tidal litter on the strand line or a plant.

 

On the Sefton Coast the sand is rich in particles of basic minerals such as calcium carbonate and the substrate therefore has a very high pH.

On another page in this section is a 'Model of Dry Dune Succession' that summarises common pathways for succession on the dunes of the Sefton Coast. This model can be used to access further information on the processes involved in primary succession.
