A simple physics-based mathematical algorithm is
described for estimating the separation etation.
distances necessary to prevent radiative ignition of
structures by burning vegetation. The algorithm is
directed at use in applications such as the USDA Forest
Service EcoSmart software suite of tools. The algorithm
represents a firphenomena involving both structures and

experiments to characterize the heat release rate (HRR),
flame height, and duration of burning for individual
Douglas-fir trees are provided. In addition, research
