The program, a joint collaboration between MidCoast Council and the National Parks and Wildlife Service (NPWS), will cover several areas on the coastal strip within the Mid Coast region.

The area from Crowdy Head south to Redhead, will be treated from Monday, June 17 through to Friday, June 28, weather permitting.

Sections of beaches and some adjacent camping areas, carparks and roads will be subject to short term temporary closures on the days when spraying occurs.

This work follows for annual Bitou Bush Bash at Crowdy Bay National Park with marked its 40^th year in April.

And last month areas of coastal national parks between Hat Head and Harrington on the NSW North Coast were temporarily closed for aerial spraying of the noxious weed.

"The combined efforts of both council and NPWS over the past decade have seen a huge reduction of mature Bitou Bush in managed areas," council's strategic weeds biosecurity officer, Terry Inkson said.

"However these ongoing treatments are necessary to control re-emerging juvenile plants and to bring previously unmanaged areas into the program."

Bitou Bush (or Chrysanthemoides monilifera), a native to South Africa, was widely planted in Australia in the 1950s and 1960s to stabilise mined sand dunes. However, in 1999 it was listed as a threatening plant species and is now a Weed of National Significance, impacting about 80 per cent of the NSW coastline (more than 900km).
