<h3>What is Ecological Succession?</h3>

Ecological succession is the process of changes in the species structure of an ecological community over time. The time scale for a succession to take place can be decades or more or less.

Succession begins with a relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable as a climax community.

The reason of succession is the cause of ecosystem change. It is the impact of established organisms upon their environments.

Succession is of two types: Primary Succession and Secondary Succession. When succession takes place on a bare rock then it is called primary succession as no species ever existed on that rock. However, when a forest catches fire the succession is secondary as species once existed on that place which were destroyed.

The time for secondary succession is less than the primary succession. The forest A which was near to the village will be saved by the local volunteers and hence it suffers less damage as compared to forest B which was far away.
