DENDROLOGY

Detailed explanation-1: -If succession has reached its climax community, then in about another 500 years what will happen? Primary succession will start over.

Detailed explanation-2: -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-3: -The process of primary succession can take hundreds, if not thousands, of years. In contrast, the process of secondary succession can reestablish an ecosystem’s climax communities in as few as 50 years.
