Conflagration: A large and destructive fire, usually aggravated by strong winds which carry firebrands over natural or manmade barriers.
Controlled burning: Fire used for kind management purposes (e.g., range improvement) foi- which advance preparations are limited to installing control lines around the perimeter and sometimes crushing the vegetation to get
it hotter fire. The only weather factor usually considered is wind of such force as to make fire control difficult.Cycle time: The average time in years between vegetation fires in a given area. Usually applied only to fires of coil flagration magnitude.
Dooryard: That area adjacent to a residence which is regularly used by the occupants and on which the native vegetation has been removed or modified, including driveways, parking areas, lawns, patios, play areas, etc.
Fuelbreak: An area, usually a long strip strategically located, wherein vegetative fuels are reduced in volume and maintained so as to produce a reduction of fire intensity if a wildfire burns into it.
Greenbelt: An irrigated, landscaped, and regularly maintained fuelbreak, usually put to some additional use (e.g., golf course, park, playground).
Mediterranean climate: A relatively mild weather pattern characterized by winter precipitation and long, hot, and dry summers.
Planned unit development: A real estate development, usually of large scale, which is planned and developed as a complete community, including residential, commercial, recreational, and school facilities as
it minimum.Prescribed fire: Fire used for land management purposes which is conducted tinder previously prescribed conditions of temperature. humidity. fuel moisture. and wind speed and direction to achieve
a specific purpose, e.g., fire hazard reduction, site preparation for planting. control of' certain unwanted plants, plant disease control.Rural: Any area wherein the residences and other developments are scattered and intermingled with forest, range, or farm land and native vegetation or cultivated crops.
Urban: In this report refers to any area wherein the residences and other works of man form an essentially solid covering of the landscape, including most areas within cities and towns, subdivisions, commercial and industrial parks, and similar developments whether inside city limits or not.
Urban wildland interface: That line, area, or zone where structures and other human development meet or intermingle with undeveloped wildland or vegetative fuels.
Wildfire: Ail uncontrolled fire. usually spreading through vegetative fuels but often consuming structures as well.
Wildland: Ail area in which development
Is essentially nonexistent, except for roads, railroads, powerlines, and similar transportation facilities. Structures, if any, are widely scattered and are primarily for recreation purposes. Includes large cattle ranches and forests managed for timber production.
