September 19 marked the start of the prescribed burning season on the Eyre Peninsula, with a burn in Bascombe Well Conservation Park by National Parks and Wildlife Service fire crews.
Burns are also planned for Lincoln National Park and private land at Mount Hope.
Prescribed burns are only carried out when safe to do so and may be cancelled at short notice and rescheduled when better weather conditions are predicted.
NPWS fire management officer Aaron Macumber said they are "constantly" looking for the right weather conditions to conduct the burns, working closely with the Bureau of Meterology.
Mr Macumber said many of these burns can create significant smoke, which is normal in mallee vegetation.
"Prescribed burns create fuel-reduced areas to limit the spread of bushfires in strategic areas," he said.
Mr Macumber said the burn area at Bascombe Well last Thursday had very disconnected fuels, meaning it needed high winds and dry conditions for fire to carry and be successful.
"Yesterday's (September 19) weather conditions provided our crews with a great window of opportunity to create a significant fuel break ahead of the fire danger season," he said.
"It's important for the community to know we plan these burns very carefully, over long periods of time, and consider all risks to ensure we can manage them effectively.
"A number of test burns were completed prior to ignition, and we delayed the burn until the fire behaviour was ideal later in the day.
"This was supported by Bureau of Meteorology forecasts and detailed calculations of fire spread."
He said the burn on Thursday had highly trained crews monitoring the conditions on the ground throughout the operation.
"Crews conducted the burn under the diminishing winds and ahead of 20 millimetres of rain overnight, delivering an excellent result," he said.
"We take our role in reducing risk to the community very seriously and we are able to pick our conditions to conduct these burns safely - some of which require higher winds to burn effectively.
"Understandably, burn offs by private landholders without such resources were not encouraged."
He said the NPWS thanked neighbours, local CFS staff and volunteers for their support.
