Autogenic succession

In ecology, autogenic succession is succession driven by the biotic components of an ecosystem.[1] In contrast, allogenic succession is driven by the abiotic components of the ecosystem.[1]

How it occurs[edit]

The plants themselves (biotic components) cause succession to occur.

  • Light captured by leaves
  • Production of detritus
  • Water and nutrient uptake
  • Nitrogen fixation
  • anthropogenic climate change

These aspects lead to a gradual ecological change in a particular spot of land, known as a progression of inhabiting species. Autogenic succession can be viewed as a secondary succession because of pre-existing plant life.[2]


  • Improvement of site factors like increased organic matter


  • Hinders species or growth
