Ecological Succession


Warm up

Warm up…

  • What is succession?

  • In what types of areas does succession occur?

  • Is succession a good thing, a bad thing, or both? Explain.


Ecological succession

  • Gradual development of a community over time following predictable stages

  • Primary or secondary


Primary succession

Primary Succession

  • Begins in a place without any soil

  • Arrival of PIONEER SPECIES

    • lichens, etc. do not need soil to survive

Ecological succession

  • Soil forms

    • Weathering and erosion break down rocks, decomposition or organic material

Ecological succession

  • Simple plants grow

    • Mosses then later ferns

Ecological succession

  • Grasses, wildflowers, other plants begin to grow

Ecological succession

  • Shrubs and trees grow

Ecological succession

  • Insects, small birds, and mammals move in

Secondary succession

Secondary Succession

  • In a place that has soil & living organisms

    • Example: after forest fires

  • Faster

  • Different pioneer species

Climax community

Climax Community

  • End result of succession

  • Stable group of plants and animals

  • Not necessarily big trees

    • Ex: grasses in prairies, cacti in deserts


Ecological succession

  • Sequencing Succession

    • Put the pictures on your desk in order from the beginning to the end of the succession sequence

    • Decide if it is primary or secondary succession

    • Explain the process


Ecological succession

  • Compare and contrast Primary and Secondary succession

    • What are the conditions?

    • How long does it take?

    • What does it start with?

    • What are the pioneers?
