ABSTRACT -- This paper describes a canopy fuel treatment standard based on models of crown fire flame size, initiation, spread rate, and firefighter safety. Site-specific prescriptions can be developed with NEXUS or nomograms. A general prescription designed to be effective at 20-foot windspeeds up to 25 mi/h during drought summer fine dead fuel moisture conditions calls for a crown-fire-free zone 380 ft wide with a maximum canopy bulk density of 0.10 kg.m3. Minimum canopy base height ranges from 2 to 18 ft depending on surface fuel conditions; for fuel model 10 (timber litter and understory), minimum CBH is 13 ft.
