Wildland Urban Interface (WUI)

Explore these resources to help you prepare for a safe wildland fire response and to create and sustain a fire-adapted community.

Fire departments across the country are increasingly being called upon to respond to WUI fires, including brush, grass, forest fires or other outdoor fires. You may believe that you don't have a WUI problem, and that WUI fires only occur in western states, but more than 46 million residences in 70,000 communities in the United States are at risk for WUI fires.

The WUI is the zone of transition between unoccupied land and human development. It is the line, area or zone where structures and other human development meet or intermingle with undeveloped wildland or vegetative fuels. Communities adjacent to and surrounded by wildland are at varying degrees of risk from wildfires.
