Climate change and Brisbane biodiversity/ by Tim Low

"The present report identifies the key threats posed by climate change to Brisbane biodiversity, identifies key actions to address inadequacies and identifies information gaps. The major conclusions are: Under climate change, Brisbane Forest Park and contiguous forest offers the best prospects for conserving high biodiversity, due to the very large area embracing a large altitudinal range. Its protection should be of the utmost priority. Under climate change, Brisbane can eventually expect an explosion of weeds. As native plants become stressed from climate change, they will very often be replaced by weeds, of which more than 1,000 species are present in south-east Queensland. The BCC can best mitigate against this be eradicating scarce weeds of high invasion potential, by targeting flammable grasses and lantana, and by enlisting community support for weed control as a core element of climate change adaptation. Under climate change, the fire risk to Brisbane Bushland will rise substantially. The BCC needs to invest more in fire management. Flammable pasture grasses and lantana need controlling as a high priority".
