| quote | Detailed study of the destruction from the Grass Valley Fire showed that high intensity forest fire was not a direct factor in igniting the vast majority of homes. Many private properties had not been adequately treated for fuels, and a high number of homes in the area were constructed from highly flammable materials, including wooden decks and shake roofs. Rogers et al. (2008) concluded that "homes, not the vegetation, were the primary fuel by which the fire spread." |
