Detailed explanation-1: -Answer: In abandon cropping lands, forests which are destroyed by natural calamities like forest fires, floods etc. Explanation: secondary succession is likely to occur in those areas where vegetation was present earlier but now destroyed by natural or anthropogenic actions.
Detailed explanation-2: -Secondary succession may occur in abandoned crop fields, cutover forests, areas damaged by wind storms or floods, and other previously occupied regions. The conditions that result in secondary succession are usually harsh.
Detailed explanation-3: -Secondary succession occurs when the severity of disturbance is insufficient to remove all the existing vegetation and soil from a site. Many different kinds of disturbances, such as fire, flooding, windstorms, and human activities (e.g., logging of forests) can initiate secondary succession.
Detailed explanation-4: -Secondary succession starts when a disturbance (such as wind storms, insect outbreaks, logging, avalanches, bulldozers, or fire) leaves the soil intact. Seeds, spores, and roots usually remain as well. Sites that begin with secondary succession reach the next stage more quickly than during primary succession.
