Within the Home Ignition Zone, up to what distance should vegetation management be considered?

• A. 0-100 ft
• B. 100-200 ft
• C. 0-5 ft
• D. 30-60 ft

Answer: (A)

The idea being tested is how far the Home Ignition Zone extends for vegetation management around a home. In practice, this zone covers up to 100 feet from the structure, including both the immediate defensible space closest to the home and the extended buffer out to 100 feet. Managing vegetation across this entire 0–100 foot area helps reduce fuels, break up continuous plant beds, and lower radiant heat and ember exposure that can threaten the home during a wildfire. Focusing only on a smaller range, like 0–5 feet, would miss the broader buffer where fuel reduction still meaningfully influences fire behavior, and stopping at 30–60 feet would leave out part of the zone that directly affects ignition risk for the home. Extending the boundary to 100–200 feet goes beyond the typical Home Ignition Zone and shifts attention to landscape considerations outside the immediate defensible space.
