Recently efforts have been undertaken by the Canada Parks system to incorporate prescribed burns. What they have found is a reduction in wildfire intensity in parks using prescribed burns though they did uncover some problems. In area with prescribed burns and a high herbivore population experience negative effects regarding in sapling occurrence.
Light burning is also been called "Paiute forestry," a direct but derogatory reference to southwestern tribal burning habits. [52] The ecological impacts of settler fires were vastly different than those of their Native American predecessors.

Deflagration (Lat: de + flagrare, 'to burn down') is subsonic combustion in which a pre-mixed flame propagates through an explosive or a mixture of fuel and oxidizer. [ 1 ] [ 2 ] Deflagrations in high and low explosives or fuel–oxidizer mixtures may transition to a detonation depending upon confinement and other factors.
Burning Index (BI) is a number used by the National Oceanic and Atmospheric Administration (NOAA) to describe the potential amount of effort needed to contain a single fire in a particular fuel type within a rating area.
