Forest Ecology
This guide helps you get your bearings in Forest Ecology before you start exploring the interactive timeline, framework graph, and concept maps.
Before You Dive In
- Forest ecology studies forests as ecosystems — not just trees, but the interactions between plants, animals, fungi, soils, water, and disturbance regimes.
- The central concept is succession: how forests change over time from disturbance (fire, logging, windthrow) through pioneer species to mature stands. Clements vs. Gleason (community vs. individualistic) is the foundational debate.
- Start with the distinction between old-growth dynamics and managed forests — most forests people see are heavily influenced by human management.
- Below-ground ecology (mycorrhizal networks, soil food webs) has transformed the field since the 1990s — trees are not isolated organisms but nodes in fungal networks.
Key Terms to Know
Ecological successionThe process of species composition change over time after a disturbance — from pioneer species to a mature community.
Mycorrhizal networkSymbiotic fungal networks connecting tree roots, enabling nutrient transfer between individuals ("wood wide web").
Gap dynamicsThe ecological processes triggered when a tree falls, creating a light gap that allows new growth and species turnover.
Stand structureThe arrangement of trees by age, size, and species within a forest — key to understanding habitat quality and management.
Disturbance regimeThe pattern of natural disruptions (fire frequency, storm intensity, insect outbreaks) that shapes forest composition over time.
Common Confusions
Thinking "old growth" means "climax" or static equilibrium — old-growth forests are dynamic systems with constant small-scale disturbance and regeneration.
Assuming forestry and forest ecology are the same — forestry is the management of forests for human use; forest ecology is the science of how forests function.
Oversimplifying mycorrhizal networks as trees "helping each other" — the interactions involve both mutualism and competition, and the fungal partners have their own interests.

2015How to Use the Interactive View
1
Explore the timeline
Open the interactive view and scan the framework timeline. Which frameworks came first? Which ones overlap? Where are the big transitions?
2
Read the articles
Click into individual frameworks to read what each one claims, where it came from, and how it relates to its neighbors.
3
Check the concept map
See how the key ideas within a framework connect. This is useful for figuring out what to learn first and what depends on what.
4
Test yourself
Take the quiz for any framework you've read about. It's a quick way to find out whether you actually understood the core ideas or just skimmed them.
