After a fire burns underground fuels, it can create a void that becomes filled with ash from the burned fuel. There are several environmental factors that increase the likelihood of an ash pit being formed. It may result from the presence of extensive root systems of trees and shrubs, as well as peat and deep duff covering mineral soil.
For some species of pine, such as Aleppo pine (Pinus halepensis), European black pine (Pinus nigra) and lodgepole pine (Pinus contorta), the effects of fire can be antagonistic: if moderate, it helps pine cone bursting, seed dispersion and the cleaning of the underwoods; if intense, it destroys these resinous trees.

Slash-and-burn fields are typically used and owned by a family until the soil is exhausted. At this point the ownership rights are abandoned, the family clears a new field, and trees and shrubs are permitted to grow on the former field. After a few decades, another family or clan may then use the land and claim usufructuary rights. In such a ...

Fire regimes of United States plants. Savannas have regimes of a few years: blue, pink, and light green areas. When first encountered by Europeans, many ecosystems were the result of repeated fires every one to three years, resulting in the replacement of forests with grassland or savanna, or opening up the forest by removing undergrowth.

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. [9]
This constant flow of air creates a hot fire that burns close to 100 percent of the wood—similar to modern smokeless fire pits that pull air from the bottom or sides to fuel your fire without ...
Wood ash from a campfire. Wood ash is the powdery residue remaining after the combustion of wood, such as burning wood in a fireplace, bonfire, or an industrial power plant.It is largely composed of calcium compounds, along with other non-combustible trace elements present in the wood, and has been used for many purposes throughout history.
