Fires can affect soils through heating and combustion processes. Depending on the temperatures of the soils during the combustion process, different effects will happen- from evaporation of water at the lower temperature ranges, to the combustion of soil organic matter and the formation of pyrogenic organic matter, such as charcoal.

Larger fires such as the Thomas Fire, which burned over 280,000 acres in Southern California in 2017, can leave behind burn scars large enough to be seen from space. More damage and destructio
Humans impact soil formation by removing vegetation cover through tillage, application of biocides, fire and leaving soils bare. This can lead to erosion, waterlogging, lateritization or podzolization (according to climate and topography). [ 83 ]
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 ...
When I arrived, the burn's incident-management team had already put together a burn plan detailing our objectives — reducing wildfire risk to the landowner's house, thinning small tree saplings ...
These smouldering fires can burn undetected for very long periods of time (months, years, and even centuries) propagating in a creeping fashion through the underground peat layer. Despite the damage that the burning of raw peat can cause, bogs are naturally subject to wildfires and depend on the wildfires to keep woody competition from lowering ...
More than 110 active fires covering 2,800 square miles (7,250 square kilometers) were burning in the U.S. on Friday, according to the National Interagency Fire Center. Fires are becoming bigger ...
Hydrophobic soil is a soil whose particles repel water. The layer of hydrophobicity is commonly found at or a few centimeters below the surface, parallel to the soil profile. [1] This layer can vary in thickness and abundance and is typically covered by a layer of ash or burned soil.
