Wildfires and Landscape Fire Regimes

A condensed, point-by-point summary of the module, for reviewing right before a test or exam.

1. Fire Ecology and Fire-Adapted Ecosystems. Many ecosystems depend on recurring fire, and their plants have evolved specific adaptations to survive and exploit it.
2. Mediterranean Climate Regions and Fire Risk. The five mediterranean-climate regions share hot, dry summers that make them the planet's most fire-prone zones.
3. Boreal Forest Fires and Carbon Release. Boreal forests store immense carbon in soil and permafrost that infrequent but intense fires can release rapidly.
4. Major Historic Wildfire Disasters. Landmark wildfire disasters, from Peshtigo in 1871 to Lahaina in 2023, have repeatedly reshaped fire policy.
5. The Wildland-Urban Interface. The wildland-urban interface, where homes meet flammable vegetation, has expanded rapidly and concentrates fire risk.
6. Indigenous Fire Management Practices. Indigenous peoples worldwide used deliberate, low-intensity burning to manage land long before colonial suppression.
7. Fire Suppression Policy and Its Consequences. Decades of total fire suppression in the United States built up fuel loads that later intensified wildfires.
8. Climate Change and Lengthening Fire Seasons. Warming temperatures are measurably lengthening fire seasons and increasing fire danger across most of the world.
