Allogenic succession

In ecology, an allogenic succession describes a succession where the stimulus for change is an external one. An allogenic succession can be brought about in a number of ways which can include:

  • Volcanic eruptions
  • Grazing animals
  • Human interference
  • Flooding
  • Non-anthropogenic climate change

An allogenic succession can be contrasted by an autogenic succession. This describes a change in succession where the stimulus for change is an internal one.
