Secondary succession stages refer to the natural process of ecological succession that occurs in areas that have previously sustained growth. It is a process of renewal that takes place when the natural ecosystem is disturbed by natural events, such as fires or human activities like logging, mining or farming. Since there is a soil layer present after the disturbance, the process starts with pioneer species that are good at establishing themselves on degraded lands. As they grow and recreate the soil layer, other plant species take root, creating a new community structure. The process continues in the same pattern until the ecosystem reaches a stable and balanced state. It is a slow but important process for nurturing biodiversity and preserving the natural environment.
