i) Nudation: which is the initiation of the succession by a major disturbance in the environment.
ii) Migration: of available seeds (species) to fill the vacant ecological niches. In secondary succession, spores and seeds may already be present in the soil awaiting the right conditions. Some plants may delay their germination – these species can be said to be better adapted to colonization than others.
iii) Ecesis: is the establishment or subsequent ability of the seeds to germinate, grow and reproduce successfully.
iv) Competition: the struggle of species for the available resources (nutrients, water, light, space). Some plants are eliminated; where as the most competitive plants are adapted.
v) Reaction: The plants continue to interact within the existing conditions.
vi) Final Stabilization: The plant community becomes stable and is referred to as the climax community. Succession is a directional vegetation change induced by environmental or other disturbances, the initial rates of vegetation change is high and subsequently falls to a low level often which further development is
governed by very slow change - the relative stable state is referred to as the climax.
