Self-thinning forest understoreys reduce wildfire risk, even in a warming climate, Philip J Zylstra, S Don Bradshaw, David B Lindenmayer, 2022

A recently published study conducted by Philip Zysltra, David Lindemayer and Don Bradshaw in the SW of WA found that over time, ‘some forests “thin” themselves and become less likely to burn – and hazard-reduction burning disrupts this process’.

‘Prior to colonisation…the tall forests with the heaviest fuel loads were deliberately left unburned (Pers. Comms Dr Wayne Webb, Pibulmun elder, 24 September 2021, (Pedro 2017 )), so that fire scars on karri were extremely rare prior to 1850, despite their ready scarring by modern prescribed burns (Rayner 1992 )’.

Health impacts of prescribed burn-offs significant but not well appreciated, Cate Swannell, 20 April 2020


'WHILE prescribed burning of landscapes reduces the risk of bushfires, the health impacts are not widely appreciated and need to be better incorporated into the risk management of burn-off activities....'

“The estimated smoke-related costs of wildfires were highest in 2012 ($24.8 million); in many years, prescribed fires often accounted for most health-related costs, peaking in 2017 ($24.1 million).”
