a fire that may or may not approach. But the important thing here is what about the mammals,

what about the marsupials, what about everybody in that forest. And this part of the book is very

hard to read, Daniel, because the way you introduce it, we know bad things are going to happen.

What is the remedy for the koala? Do they have anything that can happen? Because you describe

one scene where the koalas are in the tree in a funeral pyre. They can't escape. Is that

is that the fate of koalas and fires? Yes, if it has fires are a natural and intrinsic part of

Australia's ecology now, particularly the Eucalypt forest. The Eucalypt forest are highly flammable.

And over the last 100,000 years, fires become a very constant part of the environment. So a lot

of species have adaptations to fire. But at an individual level, they're still very devastating.

So when fires come through an area, it is difficult for koalas to escape. And particularly when

they're fierce fires. So we need to distinguish between cool fires as we call them and intense fires.

So when a fire burns lightly through the vegetation, it just burns the undergrowth. And koalas

would be relatively safe from that up in their trees. But the trouble with a lot of many of the changes

in our climate and also the changes in our land management is that we no longer have those

small cool blends. We tend to have no fires and then really intense hot fires which can burn

right up into the canopy. And of course, there's no escape for koalas from that. Sometimes they can
