all that resin-laden fauna!

I'd never considered that! Help! I'm being threatened by explosive koalas! I suspect it would be eucalyptus oil rather than resin though. :)

Arnie, even on the outskirts of major cities many people choose to live in timbered areas for the beauty and lifestyle - I'm guilty of that. It would take a change of mind-set for these people to move. That probably wouldn't happen when the risk is seen to be low but if it becomes an annual event I guess it could. An interim step would be to increase pressure on land managers to improve fire control measures, for example controlled burns to reduce vegetation litter.
