A Forestry Corporation spokesman said these were the only areas to be impacted by the immediate closures.

State forests will be closed to the public until further notice due to the ongoing fire risk.

Forestry Corporation senior manager forest stewardship Kathy Lyons urged visitors to stay out of all closed forests for their safety.

"The landscape is incredibly dry and there are already extensive fires. Conditions can change rapidly and there remains a continued heightened fire risk until we have substantial rain," she said.

Ms Lyons said state forests in northern NSW, which have already been affected by bushfires, may remain closed for extended periods due to the high risk of trees falling after fire.

"There are many large dangerous fires moving across the landscape and we expect the high fire danger to continue for the foreseeable future," she said.

"There is a very high risk to public safety, so do not enter these forests until further notice."
