As homeowners build in the wildland-urban interface (WUI), they must take special precautions to protect their lives, homes, and property. One way to do this is to create a defensible space around your home. This is the area between your home or other structures, where potential fuel (materials or vegetation) have been modi-ﬁ ed, reduced, or cleared to create a barrier and slow the spread of wildﬁ re toward your home.
A defensible space also allows room for ﬁreﬁghters to ﬁght the ﬁre safely. Three critical steps in creating a defensible space include using ﬁre-resistant building materials (for example, rooﬁng materials), reducing wildland fuels around the home, and using ﬁre-resistant plant material in the landscape.
What are ﬁre- resistant plants?
Fire-resistant plants are those that do not readily ignite from a ﬂame or other ignition sources, such as embers. These plants can be damaged or even killed by ﬁre; however, their foliage and stems do not signiﬁcantly contribute to the fuel and, therefore, the ﬁre’s intensity. There are several other signiﬁcant factors that inﬂuence the ﬁre characteristics of plants, including plant moisture content, age, total volume, dead material, and chemical content.
BUT Fire-resistant does not mean ﬁreproof. Even if you have fire resistant plants in your landscaping be sure to keep them irrigated and maintained. Plants that are ﬁre-resistant have the following characteristics:
• Leaves are moist and supple.
• Plants have little dead wood and tend not to accumulate dry, dead material within the plant.
• Sap is water-like and does not have a strong odor.
• Sap or resin materials are low.
