Succession starts with the initial colonisation of an area and usually progresses through several distinct stages before reaching a stable climax community. A succession which is prevented from reaching its natural climax (usually as a result of human activity) is called a deflected succession. Colonisation is the term used to refer to the first community that settles on the potential site for succession. One example of colonisation and succession is the potential site of bare rock.

These are the pioneer colonisers of bare rock. Lichens are
