Fires can burn at three elevation levels. Ground fires will burn through soil that is rich in organic matter. Surface fires will burn through living and dead plant material at ground level. Crown fires will burn through the tops of shrubs and trees. Ecosystems generally experience a mix of all three. [10] [11]
Ground fires use glowing combustion to burn organic matter in the soil. Surface fires burn leaf litter, fallen branches, and ground plants. Crown fires burn through to the top layer of tree foliage. [7] Fire-line intensity is the energy released per unit of measurement per unit of time and is usually a description of flaming combustion. [4]
"Ash from a chaparral [vegetation] fire is clean; it contains nutrients like phosphorous and potassium that can be beneficial," said Garn Wallace, a biochemist and soil scientist whose business ...

However, this oxygen suppression method can be compromised if cracks develop in the soil cover due to settlement. Nearby streams can be threatened by leachate pools which may form if water is used to extinguish fires in landfills. for this reason, recirculation of fire fighting water should be considered to minimize environmental impacts.

The ecological theory of alternative stable states describes how different ecosystems can exist side by side, and how they can shift as a result of disturbance. Applied to fire ecology, the theory describes how flammable and less-flammable vegetation types can exist side by side, and are maintained by different relationships with fire. [3]
