Sitting a little above the more famous lake of Cradle Mountain National Park , Tasmamia – Dove Lake, is Wombat Pool. Some tourists are confused by the name – assuming its a good place to see wombat. It’s perhaps not a good idea to tell them it was named by a pioneer of the park,… Continue reading Are the consequences of a fire in Tasmania 3,600 years ago, still present?

How to Thoroughly Confuse Everyone about Prescribed Burning in Australia
In the last couple of days, something of a ‘blue’ has developed among some Western Australian fire experts over ‘Prescribed Burning’ – the deliberate lighting of fires as part of fire management policy. On Jan 22, Byron Lamont and Tianhua He published a short opinion piece in ‘WAtoday’ called ‘Why prescribed burns don’t stop wildfires’.… Continue reading How to Thoroughly Confuse Everyone about Prescribed Burning in Australia
Did Queensland Rainforest Spread when Cultural Burning Stopped?
“This is the Giant Stinger tree – avoid it”. Work place health and safety now out of the way, I could then get on with introducing my students to Australia’s forests. *** In Queensland’s O’Reilly’s/Lamington Park I began my student classes with a walk down the road. There happened to be a convenient juvenile ‘Giant… Continue reading Did Queensland Rainforest Spread when Cultural Burning Stopped?
Australia’s Black Thursday Fires 1851 – how big and why?
Have you noticed? Despite Australia’s on-going fire disaster, there are no shortage of reports telling us to … relax – it’s nothing new, and that it’s the fault of not enough hazard-reduction burning. And certainly, it’s nothing to do with global warming, which by increasing temperature, has exacerbated what would already be an extreme drought.… Continue reading Australia’s Black Thursday Fires 1851 – how big and why?
Australia – both Greening and Burning?
Once again, the south east of Australia has had huge fires. But how can this be? Atmospheric carbon dioxide levels are rising, carbon dioxide is ‘plant food’ and apparently the result is ‘global greening’. The greening phenomenon is actually real. Studies have shown that world vegetation has thickened, and that some of this is due… Continue reading Australia – both Greening and Burning?
How You Can Predict Bushfires in Australia – Four Days Out
Tomorrow, Tuesday Nov 12, 2019 is looking very bad for south-east Australia (especially New South Wales, but also parts of Queensland, Victoria and South Australia), and this was clear at least four days ago. The reason for this is the ‘synoptic’ pattern of atmospheric circulation that has been predicted for Tuesday – and how this… Continue reading How You Can Predict Bushfires in Australia – Four Days Out
Aboriginal Paintings of the Kimberley- very old Pleistocene or not so old Holocene?
Many of the real advances in science seem to come from a sudden ‘insight’ ( think Archimedes and “Eureka!”) – and there is often no simple connection between collecting data and that ‘aha!’ moment. The tedious data collection happens, but at some moment, the brain, perhaps quite subconsciously, puts two and two together, and comes up… Continue reading Aboriginal Paintings of the Kimberley- very old Pleistocene or not so old Holocene?
Tim Flannery and Megafaunal Extinction Shuffle-puck

In 1994 an influential book, ‘The Future Eaters’, was published by the Australian paleontologist Tim Flannery. One of the goals of the book was to explain why an event several thousand years ago (the extinction… Continue reading Tim Flannery and Megafaunal Extinction Shuffle-puck
Australian Grasstrees – ancient registrars of fire
In Australia there are trees that look like inside-out chimneys. Strong but sensitive – a fungal attack can leave them as a pile of mush within days, and, often as not, they won’t survive being transplanted from the wild. But, you can burn them to a crisp – and they will re-sprout, again, and again,… Continue reading Australian Grasstrees – ancient registrars of fire
Australia’s Fatal Fire-Flume
The first time I came to Brisbane in the hot part of the year – I couldn’t believe how anyone could survive there. The nights were oppressively, putridly hot, and full of bitey-insects. Then I ended up living there and suffered for years. I would cocoon myself in a mosquito net, and poke a fan… Continue reading Australia’s Fatal Fire-Flume
