The National Parks and Wildlife Service (NPWS) in conjunction with the Rural Fire Service is planning a three-day hazard reduction burn in Jilliby State Conservation Area, beginning Wednesday 28 April.
NPWS Central Coast Area Manager Steve Atkins said the purpose of the multi-day, 550-hectare burn is to protect high voltage transmission lines and rural properties in Central Mangrove.
"Over the next few days, there may be smoke impacts for residents in Central Mangrove, Mangrove Mountain and Wisemans Ferry, as well as for Ourimbah and Wyong on the Central Coast," said Mr Atkins.
"If you are a resident that is vulnerable to smoke, we encourage you to stay indoors as much as possible and keep doors and windows closed to reduce exposure. We also recommend that you remove washing from outdoor clotheslines and ensure your pets have a protected area.
"A helicopter will be providing air support throughout the day on Wednesday.
"The Easement Trail north off Hallards Road in Jilliby State Conservation Area will be closed for walkers for the duration of the burn. Motorists using George Downs Drive and Wisemans Ferry Road are reminded to use caution and drive to conditions.
The low-intensity hazard reduction burn has also been planned to protect rainforest habitat which is important for the vulnerable Spotted Tailed Quoll, Powerful Owl, Sooty Owl and Masked Owl.
All burns across NSW will continue to be coordinated with the NSW Rural Fire Service (RFS) to ensure the impact on the community, including from smoke, are assessed at a regional level.
Details on specific burns will be made available in advance on the Rural Fire Service website, 'Fires Near Me' app, and on NPWS Alerts website.
