The red gum is the predominant naturalized Eucalyptus in southern California, and the source of most of the drama in the fires of recent years. I've seen the ferocity of it (but we love those trees so much) in what seemed to be a huge, cataclysmic event. However, I think you must be dealing with it on a far greater scope - I'm looking for fire maps now.

(I read you have the military working on it - We had a huge bureacratic snafu, with plenty of Navy helicopters available, but lacking legal authority to interfere with civilian matters. I think they've straightened that out.)
