In WUI terminology, which term describes the boundary area between houses and wildland fuels?

• A. Intermix
• B. Interface
• C. Interlace
• D. Intermesh

Answer: (B)

In WUI terms, the boundary area between houses and wildland fuels is the interface. It marks the transition from developed space to natural fuels and is the focal point for fire-prevention planning, access, and suppression decisions because it defines where homes meet vegetation and where fire behavior changes. The other terms aren’t used to describe that boundary: intermix describes housing and fuels mixed within the landscape without a clear edge, and interlace/intermesh aren’t standard WUI terms for this boundary.
