The Parks and Wildlife Service at the Department of Biodiversity, Conservation and Attractions is conducting prescribed burns two kilometres north-west of Margaret River on Thursday, December 17.
Motorists should take care, turn on headlights and carefully follow traffic management signs when driving through areas affected by smoke.
People with conditions exacerbated by smoke should take precautions in line with their medical advice for these circumstances.
Prescribed burns create low-fuel areas in a mosaic of burnt and unburnt patches across the landscape, which help stem the spread of bushfires.
It is the primary tool available to the department to manage fuel loads, which helps protect the community by minimising the impact of bushfires.
Prescribed burning may be conducted by multiple government agencies and private landowners as part of our shared responsibility for keeping communities safe.
