Primary succession is one of the two types of ecological succession in which a barren area of land (with no soil) is colonized by organisms called PIONEER SPECIES for the very first time.
Primary succession is characterized by a BARREN area that had no form of previous growth or colonization. These barren area can include a retreating glacier, an emerging islands or the formation of new lakes.
Note that, the succession that occurs AFTER A FIRE or any form of environmental disturbance is SECONDARY SUCCESSION.
