Fire resistance refers to a plant’s reduced tendency to ignite or sustain burning compared to other vegetation, due to traits such as high leaf and tissue moisture content, low volatile-oil or resin content, thick insulating bark, sparse branching, and minimal accumulation of dead material. Fire-resistant plants are not fireproof, they can still burn under extreme conditions, but they slow fire spread and reduce ember production compared to more flammable species. They are used in defensible-space landscaping around buildings and in green firebreaks, strips of low-flammability vegetation planted to interrupt fuel continuity in fire-prone areas.
