What is an important feature of defensible space in zone 1?

An important feature of defensible space in zone 1 is to install non-flammable ground cover. This area serves as the first line of defense against wildfires, and its primary purpose is to minimize the potential for fire to ignite structures. Non-flammable ground cover can include materials such as gravel, stone, or other fire-resistant landscaping options that do not contribute to the spread of fire. By utilizing these materials, homeowners can significantly reduce the risk of flames reaching their home, which is crucial in protecting buildings from the intensity of a wildfire.

Choosing appropriate ground cover that is less combustible can slow the progress of fire and help to protect the structure in a wildfire situation. This is in contrast to the other options that could increase fire risk, such as planting a variety of vegetation close to windows, stacking firewood against the house, or leaving tree branches unpruned, which can create ideal conditions for fires to spread toward structures.
