Definition of Secondary Succession
Secondary succession is a type of ecological succession. It is defined as the recolonization of the habitat of the population of plants as well as animals after a great disturbance has occurred to their previous habitat. The disturbance can be caused by several factors like unusual flooding, a wildfire, land sliding, volcanic eruptions, deforestation, etc.
These factors do not eliminate life from such regions but quite affect them significantly. In primary succession, life starts from a barren land whereas, in secondary succession, the region already possesses soil. The climax community can be established in less than 50 years in secondary succession.
