Human intervention will not stop this plague.

I agree completely. Once the pathogen escapes, it's too late to do anything about it.

I've heard it's beginning to infect the Redwoods also.

Not from what I have seen. Redwoods may host the disease, but I haven't noticed any mortality. Zero. Bays are minorly affected (leaf spotting) and if are already stressed might die. Toyon bushes appear to be the most affected understory speices.

Too bad it doesn't kill broom.

"Too bad it doesn't kill broom."

No kidding! Until two years ago the Washington State Transportation Department planted it at road building projects!

If plants exist that display a tolerance or resistance to this fungus, how difficult would it be for that trait to be selected and incorporated into susceptible species?

I know this is, at best, a distant solution, but is it possible?
