Eucalypt forest fires are bad because the leaves are full of oil and when it's hot, dry and windy, they're extremely flammable and the fire races through the tops of the trees at incredible speeds, and jumps across large fire breaks that appear to be wide enough that they should stop it.

But at the same time the wood is also very dense, so makes great campfire wood, but doesn't burn so much in a forest fire, which is a bit ironic...

> While I'm at it, Eucalyptus trees have very very dense wood which means the wood burns very hot. This makes it even worse for forest fires where Eucalyptus trees dominate.

Forgive my ignorance, but I had understood the density of the wood meaning that the trunks of the trees were less likely to burn in a forest fire (which eucalypts encourage by shedding large amounts of dry bark)
