Australian mammals: Have they a future?
To celebrate: Australia has the most distinctive mammals in the world. To lament: 10 percent of species unique to this country have been lost in 200 years, more than was realised and far more than anywhere else.

But we can stop the losses, say ecologists John Woinarski, Andrew Burbidge and Peter Harrison. Their new action plan tells us how.
