ecological succession
Ecological Succession
  • Primary succession - establishment of

biotic factors on baron (rock) land

  • Pioneer species - first plant species in

primary succession - attach to rock,

Mosses lichens

ecological succession3
Ecological Succession:

*Successional species

*Early successional species - close to ground

*Mid successional species - herbs, grasses,

low shrubs

*Late successional species - trees

Ecological Succession:
  • Secondary succession - establishment

of new biotic factors in a previously

Vegetated area (has some soil or

sediment)

  • Disturbance -

change in

environmental

conditions that

affect a community

or ecosystem, fires

floods, mining,

clearcutting

ecological stability and sustainability8
Ecological Stability and Sustainability
  • Intermediate disturbance hypothesis -

Communities that experience fairly

frequent, but moderate disturbances

have the greatest species diversity

Moderate disturbances allow room for

colonizing species to enter ecosystem

Example: Lodgepole pine
