Management of oaks requires knowledge of tree response to fire. This knowledge is gathered through visual and other evidence of damage and of recovery, or death of the tree under various conditions such as fire conditions, weather conditions, and tree characteristics, particularly bark properties. Published information and field observations of five southern California oak species indicate that significant differences in oak species' fire sensitivity warrant consideration. The degree of trunk damage sustained is important. Coast live oak (Quercus agrifolia Nee) is extremely fire resistant, while canyon live oak (Q. chrysolepis Liebm.) almost self-destructs because of its dry, flaky bark. Bark thickness data are presented as well as methods for determining tissue viability. Recommendations for cutting or leaving damaged trees are based on species, size, and degree of trunk damage.
