What is ecological succession How long does it take to occur?

How long can ecological succession take?

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. The ecosystem’s animal populations are also established more quickly during secondary succession.

Does ecological succession happen quickly?

In secondary succession, a previously occupied area is re-colonized following a disturbance that kills much or all of its community. A classic example of secondary succession occurs in oak and hickory forests cleared by wildfire. Wildfires will burn most vegetation and kill animals unable to flee the area.

Why does ecological succession take so long?

Ecological succession takes place because through the process of living, growing and reproducing, organisms interact with and affect the environment, gradually changing it.

The establishment of a new biotic community is slow in its primary phase but gradually becomes fast in its secondary phase.

What is early succession?

Early succession is the only period when tree canopies do not dominate the forest site, and so this stage can be characterized by high productivity of plant species (including herbs and shrubs), complex food webs, large nutrient fluxes, and high structural and spatial complexity.
