Here's another reason to stop land clearing: it's making Australia hotter and drier.
The invasive mesquite tree has a negative impact on everything from biodiversity to human health. Management programmes are crucial.
Study using tree ring data and climate projections shows that buildup of CO2 will not benefit most northern forests and that growth rates will actually fall.
After some unusually wet years, our landscape and ecosystems have once again returned to poorer conditions that were last experienced during the Millennium Drought.
We'll have to get our priorities in order to protect Australia's wildlife.
Cutting-edge urban foresters argue not only for the intrinsic value of trees but also for the many economic and health benefits.
