On the continuing theme of the demise of laws designed to protect Australian biodiversity (see here, here and here), I’m reproducing our latest Nature Correspondence on the issue. I know this might be slightly dodgy to do so, but given that it’s only a Correspondence, I don’t think I’ll get in too much trouble. Besides, it’s too important an issue to hide away behind paywalls.

Policy and legislative changes by Australia’s state governments are eroding the vital protection of the country’s unique biodiversity.

Reserves are being opened up to ecologically disruptive activities, such as grazing by domestic livestock, logging, mining, recreational hunting and fishing, and commercial development. Protected habitats on private and leasehold land are imperilled too. Queensland and Victoria, for example, are relaxing hard-won laws that limit vegetation clearance on private land, further accelerating the loss of regional biodiversity.

Collectively, these actions increase the pressure on biodiversity conservation in protected areas, many of which are already showing biodiversity loss (for example, the Kakadu National Park in northern Australia). Ecological connectivity is being lost, which will hamper the dispersal of species and their ability to respond to climate-change effects.

Species extinctions are primed to increase. Too many of the country’s unique fauna and flora have been wiped out over the past two centuries (see, for example, C. Johnson Australia’s Mammal Extinctions; Cambridge Univ. Press, 2006), including the Christmas Island pipistrelle bat (Pipistrellus murrayi) in 2009.

There could be no worse time to weaken reserve protection and relax laws designed to reduce habitat loss.
