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]
In the world of wildfires, there are basically two kinds of ash: the good kind from burned vegetation that enriches the soil and the very bad ash from urban wildfires that's created when everyday ...
High temperatures can harm the soil, damaging it physically, chemically or sterilizing it. Broadcast burns tend to have lower temperatures and will not harm the soil as much as pile burning, [44] though steps can be taken to treat the soil after a burn. In lop and scatter burning, slash is left to compact over time, or is compacted with machinery.
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]

Secondary succession is the secondary ecological succession of a plant's life. As opposed to the first, primary succession, secondary succession is a process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting ...
PAM binds soil particles, increase soil stability and infiltration, and reduce soil erosion. However, studies on their effectiveness in fire-affected areas are inconclusive or show no significant effect on runoff and erosion [6] [8] [9] Combined treatments: Seeding has been frequently combined with fertilizers to increase the viability of the ...
