Glossary

Crown fire A forest fire that has ascended from the ground into the forest canopy and spreads from treetop to treetop, often with great speed.
Ecoregion An ecological and geographically defined area with geographically distinct assemblages of natural communities and species.
Fire regime The range of variability in fire characteristics in a given area over a set period of time. It includes fire frequency, predictability, intensity, seasonality, and size.
Fuels treatment Any measurable procedure taken to lower the risk of wildfires by managing vegetation to reduce hazardous fuels. Example actions include prescribed burning and mechanical thinning of forests.
Light burning The use of fire at regular intervals as a management tool for ecosystem or livelihood objectives.
Line officer The official responsible for administering policy on an area of public land. The official has full authority for making decisions about and providing direction to the firefighting effort.
Managed wildfire Any unplanned wildfire used to meet specific objectives.
Mosaic Burned habitat patches of different sizes and degrees of severity in proximity to one another as a result of a wildland fire or a history of wildland fires.

Prescribed fire Any planned fire ignited by management actions to meet specific objectives.
Wildfire Unplanned fire in wildland, regardless of ignition source.
Wildland fire A general term describing any nonstructure fire that occurs in wildland areas and burns natural fuels, such as trees and grass.
Wildland–urban interface A zone where structures and other human developments meet and intermingle with undeveloped wildland.

Although ecosystems, humans, and fire have coexisted for millennia, changes in geology, ecology, hydrology, and climate as well as sociocultural, regulatory, and economic factors have converged to make wildland fire management exceptionally challenging for U.S. federal, state, and local authorities. Given the mounting, unsustainable costs and difficulty translating existing wildland fire science into policy, the National Academies of Sciences, Engineering, and Medicine organized a 1-day workshop to focus on how a century of wildland fire research can contribute to improving wildland fire management. This publication summarizes the presentations and discussions from the workshop.
