1. Ecological Succession
Gradual and orderly replacement of one plant community over a period of time
Has stages

2. Ecological Succession
Two Types
Primary Succession
Secondary Succession

3. Primary Succession The colonization of new sites Sides of volcanoes
Landslides
Flooding
Starts with the arrival of living things such as lichens that do not need soil to survive
Called PIONEER SPECIES

5. Primary Succession
Soil starts to form as lichens and the forces of erosion help break down rock to start the process of soil formation

7. Primary Succession Hickory, Oak, and Ferns, mosses, Maple Trees
and grasses
Pine Trees
Primary Succession
Pioneer
Species

8. Each stage of succession modifies the environment for the next stage
EX: Lichens will die and add organic material to the soil to help plants grow

9. Climax Community
A stable mature community that undergoes little or no change in species
This would be the Hardwood forest stage

10. Secondary Succession
Sequence of community changes that take place after a community is disrupted by natural disaster or human action
Takes less time than primary succession, because soil already exists
Same Climax Community is reached

11. Pond Succession
Increasing
Sediments
