"Preventing WUI fire disasters requires that the problem be framed in terms of home ignition potential. Because this principally involves the home ignition zone, and the home ignition zone primarily falls within private ownership, the responsibility for preventing home ignitions largely falls within the authority of the property owner" "The Wildland-Urban Interface Fire Problem: A Consequence of the Fire Exclusion Paradigm".
