This PhD research by Dr Veronique Florec explored the impacts of changing the level of investment in prescribed burning in the south west of Western Australia.
Conducted through the Bushfire and Natural Hazards CRC and the University of Western Australia, the research evaluated the impacts of increasing and decreasing the area subjected to prescribed burning annually. This identified the threshold point for maximising the benefits of prescribed burning.
Broadly, the study found that in the long term, not conducting any prescribed burning for several years can be very costly, leading to large increases in damages and suppression expenditures. Results identify a threshold point (10% of public land) up to which substantial economic benefits may be gained from increasing the area subjected to prescribed burning. But beyond this threshold, prescribed burning generates little additional economic benefits.
