Landsat’s Critical Role in Managing Forest Fires
Worldwide, fire plays a critical role in maintaining healthy forests, but fire can also be damaging. Homes are destroyed and the effects on air quality can be felt for miles. Forest fires are occurring more often and with greater intensity than in years past, and Landsat plays a critical role in understanding the impact. Landsat data enables land managers and scientists to assess the severity and extent of large fires as they plan recovery efforts; to improve safety and prevent damage to life, property and natural resources; to estimate how much pollution burning releases into the air; and to monitor the post-fire recovery of burned areas. Landsat satellites have been collecting information about forest fires since the 1970s. Landsat plays an important role in assessing the impact of fires on forest ecosystems and human society. Landsat satellites document the location and extent of burned areas, how severely fires burn, and the subsequent regrowth of the land after a forest fire. All this information helps land managers better manage our forests and other natural resources in the context of fire.
A combination of lightning, drought and human activity caused fires to scorch more than one-third of Yellowstone National Park in the summer of 1988.
The 2014 megafires in Canada’s Northwest Territories burned 7 million acres of forest, making it one of the most severe fire events in Canadian history.
By incorporating seasonal variability of herbaceous cover and biomass in the Southwest U.S., fine fuel loading can be measured. The measurements are then used to capture changes to fire behavior fuel models based on the current fire season.
