An area that is subject to, or likely to be subject to, bushfire attack.

A collective term that refers to stands of vegetation dominated by shrubby, woody plants, or low growing trees, usually of a type undesirable for livestock or timber management

A fire burning in vegetation that is predominantly shrubs, brush and scrub growth.

An area of reduced vegetation that separates wildlands from vulnerable residential or business developments. This barrier is similar to a greenbelt in that it is usually used for another purpose such as agriculture, recreation areas, parks, or golf courses.

Capability of maintaining original surface characteristics under the prolonged influence of the use environment.


The movement of fire through the crowns of trees or shrubs more or less independently of the surface fire.


An area either natural or manmade where material capable of causing a fire to spread has been treated, cleared, reduced, or changed to act as a barrier between an advancing wildland fire and the loss to life, property, or resources. In practice, “defensible space” is defined as an area a minimum of 30 feet around a structure that is cleared of flammable brush or vegetation.

A cover inserted in or over an opening or cavity to prevent the entry of burning embers.


The manner in which a fire reacts to the influences of fuel, weather and topography

A document prepared for a specific project or development proposed for a Wildland Urban Interface Fire Area. It describes ways to minimize and mitigate potential for loss from wildfire exposure.

A type of building material that resists ignition or sustained flaming combustion sufficiently so as to reduce losses from wildland-urban interface conflagrations under worst-case weather and fuel conditions with wildfire exposure of burning embers and small flames

The heat created from combustion during a bushfire

An independent agency authorized by legislation or regulation to issue determinations, orders or other instructions in respect of any subject covered by the standard.
