"Defensible space" is also used in the context of wildfires, especially in the wildland-urban interface (WUI).
Building codes in fire-prone areas typically require that structures be built of flame-resistant materials and a defensible space be maintained by clearing flammable materials within a prescribed distance from the structure.

Fire control

A defensible space, in the context of fire control, is a natural and/or landscaped area around a structure that has been maintained and designed to reduce fire danger.
In a wildfire, fire control includes various wildland fire suppression techniques such as defensible space, widening the fuel ladder, and removing fuel in the fire's path with firebreaks and backfires to minimize the brush fire reaching new combustible fuel and spreading further.

Fuel ladder

The removal of fuel ladders is part of defensible space 'firescaping' practices.

Invasive species

invasiveinvasive plant speciesinvasive plant
The disturbance of the soil surface, such as garden soil cultivation in and firebreaks beyond native landscape zones areas, destroys the native plant cover and exposes open soil, accelerating invasive species of plants ("invasive exotics") spreading and replacing native habitats. In suburban and wildland–urban interface areas, the vegetation clearance and brush removal ordinances of municipalities for defensible space can result in mistaken excessive clearcutting of native and non-invasive introduced shrubs and perennials that exposes the soil to more light and less competition for invasive plant species, and also to erosion and landslides.

This defensible space reduces the risk that fire will spread from one area to another, or to a structure, and provides firefighters access and a safer area from which to defend a threatened area.

Fire resistive plants that are not maintained can desiccate, die, or amass deadwood debris, and become fire assistive.

“The premise is that all partners recognize a general set of common operating precepts: namely, fulfilling pre-fire mitigation, defensible space, and individual responsibilities, applicable regulations; and providing a robust local response capacity … Other key steps include building community defensible space or fuels reduction zones … as an essential component of a larger integrated fuels management portfolio …”

In response, CDF stepped up its efforts to educate the public in "fire safe" principles, generally referred to as defensible space, which can prepare a home to withstand an approaching wildfire and allow the firefighting resources to focus on controlling the fire.
