Ecological succession is the observed process of change in the species structure of an ecological community over time. Within any community some species may become less abundant over some time interval, or they may even vanish from the ecosystem altogether.
Secondary succession is the series of community changes which take  place on a previously colonized, but disturbed or damaged habitat.  Examples include areas which have beeâ¦n cleared of existing  vegetation (such as after tree-felling in a woodland) and  destructive events such as fires.
