Soil burn severity interpretation
WebAug 13, 2024 · Soil burn severity was evaluated using an adapte d version of the original Composite Burn Index (CBI) proposed by Key and Benson [14]. We measured CBI values … WebBurn severity is the effect of fire on the environment. It is a way to measure changes in vegetation and soils after a fire. Burn severity is different from, but related to, fire intensity, which describes the amount of energy released from the fire. Because this is difficult to measure, flame length is often used as a proxy to assess intensity ...

WebHowever, increasing soil burn severity increased net N mineralization rates 1 year postfire, which were 10-fold higher in the highest burn severity. While fires of high severity consumed approximately five times more soil C than those of low severity, soil C pools will also be driven by indirect effects of fire on soil processes.
WebMar 22, 2024 · We analyse the effects of burn severity on individual soil properties and soil quotients in Mediterranean fire-prone pine forests immediately after a wildfire. Burn severity was measured in the field through the substrate stratum of the Composite Burn Index and soil samples were taken 7–9 days after a wildfire occurred in a Pinus pinaster Ait. … WebDec 23, 2024 · Whitman, T. et al.
