DENDROLOGY

Detailed explanation-1: -Secondary succession happens when a climax community or intermediate community is impacted by a disturbance. This restarts the cycle of succession, but not back to the beginning-soil and nutrients are still present.

Detailed explanation-2: -Secondary succession-Succession where natural communities develop in an area that was earlier occupied by living organisms that were somehow lost. It begins in areas where natural biotic communities have been destroyed such as in abandoned farm lands, deforested lands, lands that have been flooded, etc.

Detailed explanation-3: -When disturbances destroy an existing habitat, secondary succession may occur. This disturbance could be a forest fire or volcanic eruption. The plants and animals are gone, but the soil remains. Secondary succession begins on existing soil.
