Ecological succession
Secondary succession
-
Because the soil is already developed, dominance is usually achieved by the fastest growing plants namely grass.
occurs when succession starts on existing soil following the upheaval of a pre- existing ecosystem.
- This upheaval results in the removal of existing biota and allows a new ecosystem to develop on the site of the old.
- involves the recolonisation of an area after a major disturbance has removed most but not all of the organisms in a community
Primary succession
-
The organisms which first colonise the region are called pioneer species and typically consist of lichen or moss
-
- It takes centuries for a mature forest community to develop on a patch of bare rock
- a region with another soil type and climate would have a different mix of species.
