  2. Primary Succession The process of primary succession begins in essentially barren areas—regions in which the surface or material forming the foundation of the area cannot sustain life. Ex: Lava flows, newly formed sand dunes, etc.

  3. Secondary Succession Takes place following a major disturbance, such as a fire or flood. Farmland that has been abandoned can undergo secondary succession; begins in an area that already has soil.

  4. Pioneer Species Hardy species which are the first to colonize previously disrupted or damaged ecosystems, beginning a chain of ecological succession that ultimately leads to a more biodiverse, steady-state ecosystem. Ex: grasses, lichens, mosses
