Title: Ecological Succession


1
Ecological Succession
  • Terrestrial

2
Terrestrial Phases
  • Primary Succession
  • Rock
  • Lichens
  • Weeds and Grasses
  • Shrubs

3
Barron Rock
  • rock -gt lichen -gt moss -gt grass -gt shrub -gt trees

4
Lichens on Rocks
  • rock -gt lichen -gt moss -gt grass -gt shrub -gt trees
    -gt oak hickory forest

5
Collection of debris in rock crevice allows for
dust particles to collect to aid in soil
formation.

Lichens and Moss on Rocks

7
After soil forms pioneer plants invade the land.
They are small mosses and weed type plants. Then
the progression of plants and animals is like
secondary succession.

Pioneer Plants in Soil

9
Terrestrial Phases
  • Secondary Succession
  • Soil
  • Weeds and grasses
  • Shrubs (herbaceous plants)
  • Soft wood trees, pines
  • Hardwood trees, oak and hickory

10
Weeds and Grasses
11
Shrubs
  • Herbaceous shrubs and plants begin to take over
    the grass area.

12
Soft Woods
  • Trees such as pines and poplars will begin to
    grow. They require much sun light for their
    germination.

13
Hardwood Trees
  • Hardwood trees begin to take the place of the
    pines and other softwood trees. This is then
    called a climax community.
