Thinking like a multi-billion dollar mining magnate may help to preserve biodiversity:
Koalas in south-east Queensland are in trouble. They are threatened by vehicles, dog attacks and disease (see ‘Managing threats to koalas’). And these threats are growing as koala habitat is cleared to make way for new housing and industrial estates. The rate of decline is alarming, with the population crashing from an estimated 6000 individuals to fewer than 2000 in the space of 15 years. In response to appeals from koala managers, conservation scientists and the public to do something, the Queensland Government has allocated $26.5 million to managing koalas in south-east Queensland over the next four years. How should we spend this $26.5 million to maximise the chance of koalas persisting in South-East Queensland?
