Req 6 — Reading Ecological Succession
This requirement covers two linked ideas:
- What succession means in ecology
- How to read a real landscape and explain how it changed in the past and may change in the future
Requirement 6a
Succession is the natural process by which a habitat changes over time. Bare ground may become grassland. Grassland may become shrubland. Shrubland may become young forest, and young forest may later become mature forest. Not every place follows the exact same pattern, but the big idea is that communities of plants and animals shift as conditions change.
A disturbance often starts or restarts succession. Fire, flooding, storms, farming, logging, erosion, or abandoned fields can all change what grows next.

Requirement 6b
This is where the idea becomes real. You are acting like a field ecologist, using clues to reconstruct the past and predict possible futures.
What clues to look for
Notice whether the site has bare soil, annual weeds, grasses, shrubs, young trees, or a mature canopy. Then ask what animals fit that stage. Meadow birds, pollinators, rabbits, and deer may use open ground differently than owls, salamanders, and shade-loving plants in older forest.
Thinking backward
If you are standing in a meadow with a few young trees, maybe the place used to be a farm field or a recently disturbed opening. If you are in a dense young forest, perhaps it was logged or cleared decades ago. Stumps, fencing, drainage ditches, invasive plants, or old road beds can all be clues.
Thinking forward
If disturbance stops, shrubs may thicken, trees may spread, shade may increase, and the animal community may change too. But future disturbance could send the area in another direction. Floods, fire, mowing, invasive species, or development might change the path.

Succession field notes
Questions to answer while you are on-site
- What plants dominate here now?
- What animals or signs of animals fit this stage?
- What evidence suggests an earlier stage?
- What disturbance may have shaped this place?
- What might the site become if current trends continue?

Succession helps you see nature as a moving story, not a frozen picture. The final badge requirement asks how this knowledge could shape your future through a career or hobby.
