DENDROLOGY

Detailed explanation-1: -Species diversity decreases during succession. Communities in which such large patches are rare are characterized by a large number of species that reach the canopy through small gaps and realtively few which regenerate in the large clearings. Diversity increases during succession following a large scale disturbance.

Detailed explanation-2: -As succession proceeds, pioneer species will tend to be replaced by more competitive species, the abiotic environment will become less harsh, and biotic interactions such as competition and predation will be more common.

Detailed explanation-3: -Ecological succession is important for the growth and development of an ecosystem. It initiates the colonization of new areas and the recolonization of the areas that had been destroyed due to certain biotic and climatic factors.
