Question

Explain the following sequence of succession after a forest fire.

Answer 1

The sequence of stages in a forest ecosystem (secondary succession) after fire is as follows:

Forest → Forest fire → Severe forest fire → Total nudation of forest land → Terrestrial plants → Shrubs → Woodland Stage → Forest Stage The forest fire leaves behind an empty but not destroyed soil (Nudation), over which secondary succession begins.

1. Terrestrial plant stage: Grasses and other herbaceous plants grow back first.
2. Shrub stage: Small bushes and trees begin to colonize the area
3. Woodland stage: Fast-growing evergreen trees grow tall, while shadetolerant trees develop understorey.
