Pyrophytes (fire-adapted plants) like lodgepole pine and banksia have serotinous cones sealed by resin that only open after fire, ensuring seeds germinate in nutrient-rich ash with reduced competition.
Post-fire succession proceeds through predictable stages: pioneer herbs → shrubs → early forest → climax community. Fire resets the clock, creating a mosaic of different successional stages across the landscape.
Many ecosystems evolved with fire every 2–50 years. Suppression of natural fires allows fuel accumulation, making eventual fires more intense and ecologically damaging — paradoxically harming fire-adapted species.
Fire rapidly releases carbon stored over decades but also volatilizes nitrogen while making phosphorus and other minerals immediately plant-available. Net ecosystem carbon balance depends heavily on fire frequency and intensity.
